Sell Smarter: 10 Best Sales Intelligence Software I Recommend

April 3, 2025

best-sales-intelligence-software

Early in my career, I worked with a small D2C company with a great product and a motivated team. However, we had one problem—we didn’t have clear insights into our prospects. As marketers, nothing could be worse. Our outreach was based on gut feeling rather than data, and our conversion rates reflected that.

Some team members believed cold calling was the key, while others pushed for email campaigns or social selling. But without the right data, we were making decisions in the dark. That’s when we turned to the best sales intelligence tools.

After implementing these tools, everything changed. We could see which leads were most likely to convert, track buying signals, and personalize outreach at scale. Instead of wasting time on unqualified prospects, we focused on high-value opportunities and our sales skyrocketed.

If you’re struggling to identify the right prospects and close more deals, keep reading. I’ve explored the top sales intelligence tools and will share key insights to help you find the best fit for your business.

My top 10 best sales intelligence software recommendations for 2025

The best sales intelligence software helps businesses find, analyze, and engage with high-quality leads. During testing, I saw how these tools streamline sales prospecting, automate outreach, and provide actionable insights into buyer intent. Features like real-time data enrichment, AI-driven recommendations, and contact verification optimize sales efforts, making it easier to connect with decision-makers and close deals faster.

How did I find and evaluate the best sales intelligence software?

First, I explored G2 Grid Reports to identify the most trusted sales intelligence tools among professionals. Then, I tested them firsthand to assess their data accuracy, lead enrichment capabilities, and overall usability. For tools I couldn’t test directly, I gathered insights from sales professionals who rely on them daily and cross-referenced their feedback with verified G2 reviews.

The screenshots in this article come from a mix of my own testing and vendor-provided materials on G2. To ensure a well-rounded evaluation, I used AI to analyze thousands of G2 user reviews, extracting key insights and common feedback. The goal? To pinpoint the best sales intelligence software that helps sales teams find, engage, and convert prospects efficiently—without unnecessary complexity.

What I look for in sales intelligence software

When evaluating the best sales intelligence software, I focus on several key features to determine its effectiveness: 

  • Data accuracy: I test how well the software aggregates, cleans, and verifies sales data from multiple sources. Reliable sales intelligence depends on accurate firmographic, technographic, and intent data. Automated data enrichment ensures that company and contact details stay current, reducing bounce rates and outdated leads.
  • Lead scoring: I assess how effectively the platform uses artificial intelligence (AI) and machine learning (ML) to prioritize leads based on engagement, buying intent, and historical conversion patterns. AI-driven scoring models should adapt dynamically based on new data inputs, helping sales teams focus on high-potential opportunities.
  • Intent data and buying signals: The ability to track digital footprints, such as website visits, content downloads, and social media engagement, helps identify prospects actively researching solutions. I check if the software uses third-party intent data sources to provide additional context on which companies are in the market for specific products or services.
  • Contact discovery and enrichment: Sales teams need direct access to decision-makers. I evaluate how well the software provides verified contact information, including direct dials, email addresses, and LinkedIn profiles. AI-powered enrichment should continuously update and enhance contact records to prevent data decay.
  • Email tracking and engagement analytics: Integrated email tracking tools should provide real-time notifications when a prospect opens an email, clicks a link, or downloads an attachment. I test whether the platform offers A/B testing for subject lines, email copy, and send times, optimizing engagement rates.
  • Customization and reporting: Sales teams require actionable insights, so I assess how well the platform offers customizable dashboards, sales forecasting, and pipeline analytics. Interactive visualizations should provide breakdowns of key performance indicators, such as conversion rates, deal velocity, and sales cycle length. 
  • CRM integration: Seamless integration with customer relationship management (CRM) platforms like Salesforce, HubSpot, or Microsoft Dynamics eliminates data silos and enhances sales efficiency. I evaluate how well the software syncs contact details, engagement history, and sales activities to streamline prospecting and follow-ups.

The list below contains genuine user reviews from our best sales intelligence software category page. To qualify for inclusion in the category, a product must:

  • Provide information and insights about prospects, which can be combined with business data generated by companies
  • Include functionality to search company lists and identify potential customers based on custom criteria or alert salespeople with predictive insights on potential customers based on trigger events
  • Provide and source accurate contact information for potential customers, such as direct dials or verified email addresses
  • Integrate with sales and marketing software, as well as analytics, business intelligence, or data management solutions

This data has been pulled from G2 in 2025. Some reviews have been edited for clarity.

1. ZoomInfo Sales

ZoomInfo Sales impressed me immediately with its amazing onboarding process and support. The platform made it easy to get up and running quickly, with clear guidance and responsive customer support throughout. This made the learning curve much easier to manage, especially for those new to sales prospecting tools.

One of the features I found particularly helpful was the personalized sales process. It streamlined my outreach efforts and made prospecting more manageable by helping me identify leads and enabling me to document and follow up seamlessly.

The process was intuitive, simplifying the otherwise complex task of managing leads. Additionally, ZoomInfo's sales analysis and insights were incredibly valuable, allowing me to make informed decisions and refine my strategy as I went along.

ZoomInfo Sales

However, there were some challenges. Data quality issues occasionally popped up, especially when contacts were not properly linked to the correct company. This led to some confusion during outreach and meant I had to double-check contact information more often than I would have liked. G2 reviews indicate that other users have also faced similar data accuracy issues. 

Another area for improvement is the availability of mobile and direct phone numbers. While ZoomInfo provides solid contact details, I occasionally found that it lacked mobile numbers or direct phone numbers, which would have made my outreach more effective, especially when trying to reach decision-makers.

Finally, while ZoomInfo offers a robust learning platform in ZoomInfo University and its Knowledge Center, I found it somewhat difficult to navigate at times. Finding specific training materials or resources took longer than expected, and G2 reviews reflect similar feedback from other users, suggesting that a more intuitive organization of resources would enhance the experience.

Overall, ZoomInfo Sales is a powerful prospecting tool that offers excellent onboarding, personalized sales processes, and valuable insights.

What I like about ZoomInfo Sales:

  • The onboarding process and customer support impressed me from the start. The clear guidance and responsive support made the learning curve much easier, especially for newcomers to sales prospecting tools.
  • ZoomInfo’s personalized sales process streamlined my outreach efforts. It helped me identify leads efficiently and ensured seamless documentation and follow-up.

What G2 users like about ZoomInfo Sales:

"Operating in a niche industry makes finding accurate data challenging. Fortunately, ZoomInfo excels at providing reliable data while ensuring easy access, organization, and usability through lists and workflows. Our representatives leverage the browser plugin to seamlessly import contact and company data into HubSpot, saving hours of manual work each week."

- ZoomInfo Sales Review, Adam O.

What I dislike about ZoomInfo Sales:
  • Data quality issues occasionally arose, particularly with contacts not properly linked to the correct companies. This caused confusion during outreach, requiring me to double-check contact information more often than I would have liked, and G2 reviews show that other users faced similar problems.
  • The availability of mobile and direct phone numbers could be improved. Although ZoomInfo provides solid contact details, it sometimes lacks mobile or direct numbers, limiting outreach effectiveness, particularly when reaching decision-makers.
What G2 users dislike about ZoomInfo Sales:

"Syncing contact reports with your account book in Salesforce can be challenging, making it difficult to receive only updated contacts related to your accounts. This often results in spending extra time manually filtering lists to find the most relevant contacts."

- ZoomInfo Sales Review, Christoph B.

2. LinkedIn Sales Navigator

LinkedIn Sales Navigator has proven to be an incredibly valuable tool for account mapping. The ability to map accounts, view buyer insights, and create intelligent account maps helped streamline my sales process, significantly reducing manual work. This feature alone made my outreach much more targeted, saving a lot of time and effort.

Another feature that stood out was the advanced filtering options. With filters for industry, company size, seniority level, and more, I could fine-tune my searches and find the exact type of leads I was looking for. This level of customization allowed me to focus on high-priority prospects, ensuring I spent my time wisely.

Additionally, the InMail messaging feature was a game-changer. It allowed me to contact prospects even when we weren’t connected on LinkedIn, which expanded my outreach opportunities and made it easier to contact decision-makers directly.

LinkedIn Sales Navigator

Despite its powerful features, Sales Navigator sometimes feels a little outdated and complicated. This sentiment has also been echoed by G2 users, who often mention that the platform can feel cumbersome to navigate, especially for new users.

Another issue I encountered was that the tool occasionally delivers irrelevant prospects, especially those without verified emails. Some G2 reviews suggest that lead quality is sometimes inconsistent.

Furthermore, while various filters are available, the platform lacks the ability to filter leads by associated account metrics like revenue size or employee count. This limitation can make it harder to target high-value leads within specific types of organizations, which is something I hope the platform addresses in the future.

Overall, LinkedIn Sales Navigator offers solid features like advanced filters, account mapping, and InMail messaging that make it a valuable tool for sales teams. 

What I like about LinkedIn Sales Navigator:

  • The account mapping feature in LinkedIn Sales Navigator significantly streamlined my sales process. It allowed me to map accounts, view buyer insights, and create intelligent account maps, reducing manual work and making my outreach more targeted.
  • The advanced filtering options were incredibly helpful in finding high-priority leads. Filters for industry, company size, seniority level, and more helped me fine-tune my searches and focus on the exact type of prospects I was looking for.

What G2 users like about LinkedIn Sales Navigator:

"Advanced filters such as industry, company size, and seniority level make it easier to find the right leads. The InMail messaging feature allows outreach to prospects even without a direct connection. Integration with customer relationship management (CRM) platforms like Salesforce and ZoomInfo was seamless in my experience. Additionally, features like account insights provide valuable information about target companies."

- LinkedIn Sales Navigator Review, Biplab D.

What I dislike about LinkedIn Sales Navigator:
  • Sales Navigator can feel outdated and complicated at times, especially for new users. G2 reviews often mention the platform’s cumbersome navigation, which can slow down the user experience.
  • The tool occasionally delivers irrelevant prospects, especially those without verified emails. This leads to inconsistent lead quality, as reflected in G2 reviews, making it harder to trust the results at times.
What G2 users dislike about LinkedIn Sales Navigator:

"While LinkedIn Sales Navigator offers a substantial number of prospects, it sometimes includes irrelevant ones without verified email addresses, which can be frustrating for lead generation."

- LinkedIn Sales Navigator Review, Golam S.

3. Apollo.io

Apollo.io offered great value, even with its free plan. It provided access to key features that were helpful for our team without requiring an immediate financial commitment. This flexibility allowed us to test the platform thoroughly and see its potential before upgrading.

One of the standout features for me was its powerful lead database. The sheer volume of contacts available allowed us to easily find and target the right prospects. Having access to such a vast pool of leads made the tool incredibly valuable for outreach, saving time and effort in the prospecting phase.

Additionally, Apollo.io’s ease of use stood out. As someone with minimal prior experience using CRM platforms, I found the interface intuitive and easy to navigate. This made the onboarding process smooth, and I appreciated how quickly I could dive into using it without needing extensive training or experience.

Apollo.io

However, there were some areas where Apollo.io could improve. User experience issues, like button placement, became apparent during my testing. Though this didn’t significantly hinder my use of the platform, I could see that improvements in these areas would make the interface even more intuitive. Based on G2 reviews, many users echoed similar concerns about usability, but I believe that the team is working on refining this over time.

Page transitions within the platform were slower than expected, which caused some issues when navigating between sections. I noticed this slowdown frequently, and I hope the team addresses it in future updates to enhance overall speed and efficiency.

Lastly, the lack of event notifications was a downside. For instance, it would be beneficial to receive a notification when a user opens an email multiple times. I’ve seen similar feedback on G2, where users mentioned that more granular event tracking and notifications would help improve the follow-up process.

Overall, Apollo.io is a strong CRM tool, especially for its value on the free plan. 

What I like about Apollo.io:

  • Apollo.io’s free plan offers significant value, providing access to key features without needing immediate financial commitment. This flexibility allowed us to thoroughly test the platform and see its potential before upgrading.
  • The powerful lead database was a standout feature for me. The vast volume of contacts available made it easy to find and target the right prospects, saving time and effort during the prospecting phase.

What G2 users like about Apollo.io:

"The biggest advantage of Apollo.io is the ability to instantly access anyone’s email address, making outreach seamless. The automatic sequence feature helps me focus on other tasks while ensuring consistent follow-ups. Additionally, tracking sequence data allows me to refine and improve my process. I use Apollo.io almost daily."

- Apollo.io Review, Yaren.

What I dislike about Apollo.io:
  • User experience issues, like button placement, were noticeable during my testing. While it didn’t significantly hinder my use, G2 reviews suggest that many users have similar concerns, and improvements in this area would enhance the interface’s intuitiveness.
  • Page transitions within Apollo.io were slower than expected. This frequent slowdown when navigating between sections impacted efficiency, and I hope future updates address this to improve speed.
What G2 users dislike about Apollo.io:

"Apollo allows multiple mailboxes to be linked to a single name, which is helpful, but it lacks the ability to map multiple users under one account. Unfortunately, I cannot add multiple usernames within a single account."

- Apollo.io Review, Omkar G.

4. Seamless.AI

Seamless.AI delivered on its promise of reliable, real-time data collection in a simple and intuitive interface. The ease of implementation made it a smooth addition to existing workflows. I can see sales professionals quickly integrating it into their prospecting strategies without a steep learning curve.

One of the standout features was buyer intent data, which added depth to lead generation efforts. By providing insights into prospects’ readiness to engage, it helped refine targeting and prioritize high-value opportunities. Industry professionals I collaborated with found this feature particularly useful for focusing outreach on leads more likely to convert.

Beyond intent data, Seamless.AI opened up countless opportunities for cold calling. The ability to research companies and contacts efficiently made outbound efforts more strategic, helping teams reach the right people with relevant messaging. For businesses that rely on direct outreach, I see this tool as a valuable asset.

Seamless.AI

However, for businesses looking to build a multi-unit strategy, one limitation was that Seamless.AI typically provided corporate physical addresses and phone numbers rather than location-specific details. That said, the platform often compensated by including mobile numbers for key contacts, making direct outreach more effective.

Currently, you can’t set quality parameters before scraping, meaning the daily credit allotment (1,000 credits) could be spent on both high-quality and lower-value leads. Some G2 users have also pointed out this limitation, suggesting that a pre-scrape filtering option would make lead sourcing more efficient.

Additionally, understanding the credit system took some time. While it wasn’t a major barrier, a clearer breakdown of how credits are used and optimized would be beneficial. Many G2 users shared similar feedback, highlighting the learning curve associated with maximizing credit usage.

Overall, Seamless.AI is a strong tool for data-driven prospecting, offering intuitive usability, intent-based insights, and valuable contact details. With refinements in lead quality filtering and credit transparency, it could become even more efficient for sales teams aiming to maximize their outreach efforts.

What I like about Seamless.AI:

  • Seamless.AI offers a simple and intuitive interface, which makes it easy for me to integrate into my existing workflows. I was able to adapt quickly, and the lack of a steep learning curve allowed me to start using it effectively almost immediately.
  • The standout feature for me was the buyer intent data, which provided valuable insights into prospects’ readiness to engage. 

What G2 users like about Seamless.AI:

"I love that I can easily search for industries I work with and access detailed contact information. The ability to modify job titles and other criteria makes finding the right contacts effortless. Integrating them directly into our CRM is a huge time-saver, and the Buyer Intent feature is the icing on the cake—opening up endless opportunities for cold calls. This new option for researching companies and contacts is a game-changer!"

- Seamless.AI Review, Rena C.

What I dislike about Seamless.AI:
  • One limitation I noticed was that Seamless.AI typically provided corporate physical addresses and phone numbers rather than location-specific details. This can be a challenge for businesses that rely on multi-unit strategies, though including mobile numbers for key contacts did help to some extent.
  • I also found that there was no way to set quality parameters before scraping, which meant my daily credit allotment could be spent on both high-quality and lower-value leads. Many G2 users also felt that a pre-scrape filtering option would make lead sourcing more efficient.
What G2 users dislike about Seamless.AI:

"The ability to select multiple contacts using checkboxes and add them to a specific list in one click would be a great time-saver and significantly improve workflow efficiency."
- Seamless.AI Review, Rafael I.

5. Instantly

Instantly stood out to me with its clean, modern, and intuitive user interface, making navigation seamless regardless of experience level. Whether setting up campaigns, tracking performance, or adjusting workflows, the platform’s design made every action feel smooth and efficient.

While testing, another highlight was the quick setup process, which minimized the time between installation and actual use. Industry professionals I collaborated with also appreciated how quickly they could integrate Instantly into their existing outreach strategies.

The workflow customization options added to the platform’s appeal. Tailoring sequences to match specific business needs helped me gain greater flexibility, ensuring that outreach efforts aligned with different target audiences. This level of personalization made campaigns more effective and adaptable over time.

Beyond automation, the reporting system instantly delivered detailed insights and easy-to-understand reports, making data-driven decision-making more accessible. The system broke down performance metrics in a way that allowed for quick optimizations, helping me understand and refine strategies without digging through complex analytics.

Instantly

That said, the platform does have guardrails that initially feel restrictive. At first, they seemed to slow things down, but once I understood why they were in place, it became clear that they were designed to optimize long-term results. 

One limitation was third-party email host integration. I experienced some issues while setting it up, though I recognize that external factors can limit Instantly’s control over this functionality. 

Lastly, I found the mobile experience lacking. Checking Unibox for positive responses or making quick adjustments on the go wasn’t as smooth as it could have been. Many users on G2 have expressed similar concerns, noting that a more mobile-friendly interface would make Instantly even more useful for remote work.

Overall, Instantly is a powerful and user-friendly outreach tool that balances automation with insightful reporting. 

What I like about Instantly:

  • Instantly immediately stood out to me with its clean, modern, and intuitive user interface, making navigation seamless regardless of my experience level. Whether I was setting up campaigns, tracking performance, or adjusting workflows, the platform’s design made every action feel smooth and efficient.
  • The quick setup process was another highlight, allowing me to get started without unnecessary delays. Industry professionals I collaborated with also appreciated how easily they could integrate Instantly into their existing outreach strategies, minimizing downtime and maximizing productivity.

What G2 users like about Instantly:

"Instantly has been a game-changer for me. Before discovering it in mid-2023, I knew nothing about cold email or outreach and had no idea I could land overseas clients this way. Thanks to Instantly’s free resources, I quickly learned the essentials and started testing campaigns with their Growth plan. Within the first month, I secured two U.S. clients through my cold outreach and have been using Instantly effectively ever since.

I love its simple and intuitive UI/UX, packed with powerful features. The customer support is outstanding—queries are usually resolved within 10 to 15 minutes, regardless of time zone. What truly sets Instantly apart is its commitment to user feedback; when a group of users requests new features, they often appear in the next update. The Unibox feature, in particular, is one of my favorites."

- Instantly Review, Sandeep K.

What I dislike about Instantly:
  • One limitation I encountered was the platform's initial guardrails, which felt somewhat restrictive at first. While they seemed to slow things down, I eventually realized they were designed to optimize long-term results, which made the experience more efficient over time.
  • Another challenge was setting up third-party email host integration, which I struggled with. Although I understand that external factors can limit Instantly’s control over this functionality, it was still an issue that required extra attention.
What G2 users dislike about Instantly:

"Instantly AI's mobile experience feels lacking, making it difficult to work efficiently without a laptop. Checking Unibox for positive responses on a phone is challenging, and a more user-friendly mobile interface would greatly improve on-the-go usability."

- Instantly Review Lucie K.

6. Cognism

Cognism impressed me with its highly accurate, GDPR-compliant data, eliminating the frustration of chasing outdated leads. Knowing that the data met strict compliance standards gave me confidence in outreach efforts, ensuring that every prospect was reachable and legally sourced. 

The advanced targeting capabilities stood out, particularly firmographics, technographics, and intent data. These insights helped pinpoint the right prospects at the right time, making outreach more strategic and effective. Collaborating with industry professionals, I saw how this level of precision allowed sales teams to focus their efforts on high-value leads rather than casting a wide, inefficient net.

Another strong feature was access to mobile numbers and direct dials, which made it easier to connect with decision-makers. Having these direct contact details significantly reduced the time spent navigating gatekeepers and generic email inboxes, helping outreach efforts reach the right people faster.

Beyond the product, I found Cognism’s support team to be exceptional. They were quick to respond, always helpful, and full of valuable advice. Whether it was guidance on optimizing searches or best practices for using intent data, the support team ensured users got the most out of the platform.

Cognism

That said, I observed that while intent data was useful, it could be even more effective with deeper insights. Some G2 users also mentioned wanting more detailed indicators to better understand when a buyer was truly ready to engage. Enhancing this feature could further refine prospecting strategies.

Additionally, while Cognism maintains high accuracy, occasional outdated or incorrect information does appear. While such instances were infrequent, ongoing improvements in data freshness would make the platform even more reliable.

Lastly, email bounce rates were lower than those of other providers, but they still happened occasionally. While no provider can guarantee a 100% success rate, minimizing these occurrences further would strengthen Cognism’s value proposition.

Overall, Cognism is a powerful sales intelligence tool with accurate data, strong targeting, and excellent customer support. 

What I like about Cognism:

  • Cognism impressed me with its highly accurate, GDPR-compliant data, eliminating the frustration of chasing outdated leads. Knowing that the data met strict compliance standards gave me confidence in my outreach efforts, ensuring that every prospect was reachable and legally sourced.
  • The advanced targeting capabilities, particularly firmographics, technographics, and intent data, stood out. These insights help the users pinpoint the right prospects at the right time, making outreach more strategic and effective by focusing on high-value leads rather than casting a wide, inefficient net.

What G2 users like about Cognism:

"Cognism is an excellent platform for sales and marketing professionals aiming to streamline lead generation and improve prospecting. Its vast and accurate B2B contact database provides detailed company and individual profiles, making it easy to identify and connect with decision-makers—especially useful for targeting specific industries or regions.

A standout feature is its AI-powered lead enrichment, which automatically updates and enhances contact details, ensuring users always have the most up-to-date information. This not only minimizes manual data entry but also saves valuable time."

- Cognism Review, Alvaro L.

What I dislike about Cognism:
  • While the intent data was useful, I observed that it could be more effective with deeper insights. Some G2 users mentioned wanting more detailed indicators to better understand when a buyer was truly ready to engage, which could refine prospecting strategies further.
  • Although Cognism maintains high accuracy, I occasionally encounter outdated or incorrect information. This issue was infrequent, but ongoing improvements in data freshness would make the platform even more reliable and enhance its value.
What G2 users dislike about Cognism:

"Cognism provides high-quality data, but some contact information can still be outdated or incomplete. Additionally, its pricing can be steep for smaller businesses, making it less accessible for those with limited budgets."

- Cognism Review, Kevin O.

7. ListKit

ListKit stood out as an exceptional lead generation system, providing access to only verified emails. The reliability of the data made a noticeable difference in my outreach efforts, reducing bounce rates and ensuring more meaningful connections with prospects. 

One of the most valuable aspects was the monthly allocation of 10,000 fresh leads. This steady influx of new prospects held great potential for business growth, making it easier to maintain a consistent outreach pipeline. Industry professionals I worked with found this lead generation feature particularly useful for scaling their sales efforts without constantly worrying about lead replenishment.

Beyond the platform itself, the training and follow-up support from ListKit’s team added significant value. They provided clear guidance on optimizing lead generation strategies, ensuring I could fully use the system’s capabilities.

The additional 24/7 customer support further reinforced my experience, with representatives even booking strategy calls to assist with integration and best practices. Having a team that actively helps users maximize the tool’s effectiveness sets ListKit apart from many competitors.

ListKit

That said, more in-depth training would be beneficial to unlock the platform’s full potential. While the existing resources were helpful to me as a beginner, a deeper dive into advanced features could enhance the user experience for professionals who require advanced sales intelligence support. This was echoed in some G2 reviews, where users expressed interest in more comprehensive learning materials.

Additionally, the initial setup process felt slightly overwhelming for me as a beginner due to technical requirements. However, taking it step by step—and with the support team readily available—made it more manageable than it initially seemed. 

One feature I hope to see in the future is an integrated email sender within the platform. While this isn’t currently available, ListKit offers assistance setting up external email solutions, which is a helpful workaround.

Overall, ListKit delivers a high-quality lead-generation experience backed by strong support and fresh, verified data. 

What I like about ListKit:

  • ListKit stood out to me as an exceptional lead generation system. It offers only verified emails, which significantly improved the quality of my outreach. The reliability of the data reduced bounce rates and helped ensure more meaningful connections with prospects.
  • The monthly allocation of 10,000 fresh leads was another standout feature. This steady stream of new prospects makes it easier to maintain a consistent outreach pipeline and industry professionals.

What G2 users like about ListKit:

"I just started using ListKit, but what convinces me of their list quality is their commitment to customer success. From the start, they’ve provided everything I need to maximize their platform, offering guidance on sending effective cold emails and providing extensive resources. They also ensure every user gets a one-on-one onboarding call with a specialist before using their credits. So far, I’m very impressed!"

 

- ListKit Review, Zach T.

What I dislike about ListKit:
  • While the training and support were helpful, I felt that more in-depth training would be beneficial to unlock the platform’s full potential. Some G2 users noted that more advanced learning materials would enhance the user experience, especially for those requiring in-depth sales intelligence support.
  • Due to technical requirements, the initial setup process was slightly overwhelming for me, though with support from the team, I was able to manage it. Despite this, a more streamlined setup process would make it easier for beginners like me to get started without feeling daunted.
What G2 users dislike about ListKit:

"Despite reaching out to over 8,000 potential leads, we have not received a positive response. However, I understand that success takes time—Rome wasn’t built in a day. We remain committed to refining our cold email sequences and improving our approach for future campaigns."

- ListKit Review, Armando A.

8. CUFinder

CUFinder made it easy to access prospect and company data with straightforward filtering. I frequently used industry filters for companies and a combination of industry and job titles for contacts, which helped refine searches efficiently. The system provided quick access to relevant data, making it a practical tool for professionals looking to streamline their prospecting process.

One of the standout aspects was the simplicity of the platform. The interface was user-friendly, and I didn’t face a steep learning curve while navigating the system. Industry professionals I collaborated with also found it intuitive, allowing them to extract valuable insights without extensive training.

Beyond functionality, I appreciated CUFinder’s customer support. Their team was responsive post-purchase, addressing concerns and assisting with queries effectively. Strong support is a crucial factor in any sales intelligence tool, and CUFinder delivered on that front, making it easier to resolve issues and maximize the platform’s potential.

CUFinder

However, I noticed that the list and dashboard customization options could be expanded. While filtering worked well, additional search refinements and insights would enhance the experience. 

Another area for enhancement is prospect dashboard stability. Occasionally, I encountered minor bugs while searching for contacts. Similar feedback appeared in G2 reviews, where some users mentioned intermittent glitches affecting search results. Refining these aspects would make the system even more reliable.

Despite these areas for improvement, CUFinder remains a solid tool for accessing targeted business data. 

What I like about CUFinder:

  • CUFinder made it easy for me to access prospect and company data with straightforward filtering, allowing me to refine searches efficiently. Using industry filters for companies and combining industry and job titles for contacts helped streamline my prospecting process.
  • The platform’s simplicity stood out, with an intuitive interface that required no steep learning curve. Industry professionals I collaborated with also found it easy to navigate, allowing them to extract valuable insights without extensive training.

What G2 users like about CUFinder:

"We've been using CUFinder for over a year to find ready-to-buy leads, and its system sets it apart by focusing on hot leads rather than cold ones. It helps us connect with prospects who are actively searching for our services, leading to a higher lead-to-customer conversion rate. When leads are truly relevant, more of them convert, making CUFinder a valuable tool for our sales process."

-CUFinder Review, Carrick K.

What I dislike about CUFinder:
  • I noticed that list and dashboard customization options could be expanded to offer more flexibility. While the filtering system worked well, additional search refinements and insights would further enhance the user experience.
  • Another area for improvement is the stability of the prospect dashboard, as I occasionally encountered minor bugs while searching for contacts. This issue also appeared in G2 reviews, with some users mentioning intermittent glitches affecting search results, so refining this would make the system even more reliable.
What G2 users dislike about CUFinder:

"I wish CUFinder would enhance its dashboard features by adding more filters for company and people searches. Additionally, incorporating insights into the system would make it even more valuable for users."

- CUFinder Review, Williafm M.

9. BookYourData

BookYourData impressed me with its high data accuracy, boasting a 97% accuracy guarantee. The real-time email verification was a standout feature, ensuring that every contact was valid before outreach. This saved time and reduced bounce rates, making the tool particularly valuable for professionals relying on precision in their prospecting efforts.

I also appreciated the flexible pricing model, which allowed me to pay only for the data I needed—no subscription or credit card required. This pay-as-you-go approach was especially useful for businesses looking to scale their outreach without committing to ongoing costs. Collaborating with industry professionals, I found that this flexibility made BookYourData a practical choice for both small teams and larger enterprises.

BookYourData

The filtering options for industry and geography provided a solid way to refine searches, but I noticed that some niche segments had limited coverage. This observation aligned with G2 user feedback, where some users expressed a need for broader data availability in specialized industries.

Another point to consider is the depth of customization in filtering. While the platform offers notable search refinements, some users might require more advanced options for targeting specific personas. This was a recurring sentiment in G2 reviews, where a few professionals highlighted the need for even greater segmentation capabilities.

Finally, there’s the cost factor. BookYourData isn’t cheap, but after testing it, I can say it’s worth the investment. The trial version helped me understand its value firsthand, and given the accuracy and reliability, it justifies the price. For businesses prioritizing high-quality data, this platform delivers results that make the cost a reasonable trade-off. 

What I like about BookYourData:

  • BookYourData impressed me with its 97% data accuracy guarantee, ensuring every contact was valid before outreach. The real-time email verification feature saved time and reduced bounce rates, making it a reliable tool for professionals who depend on precision in prospecting.
  • I also appreciated the flexible pay-as-you-go pricing model, which required no subscription or credit card. This approach makes it practical for both small teams and larger enterprises looking to scale outreach without committing to ongoing costs.

What G2 users like about BookYourData:

"BookYourData has been incredibly helpful. I appreciate its accurate, up-to-date data with a 97% accuracy guarantee and real-time email verification, which saves time and ensures I'm reaching real people. The pay-as-you-go model, with no subscription or credit card required, adds flexibility, and the customer support is fantastic."

- BookYourData Review, Celso C.

What I dislike about BookYourData:
  • The industry and geography filtering options were helpful, but some niche segments had limited coverage. This matched feedback from G2 users who expressed the need for broader data availability in specialized industries.
  • Customization depth in filtering could be improved to allow for more advanced targeting options. While search refinements were solid, some users—including those in G2 reviews—felt greater segmentation capabilities would enhance the platform’s effectiveness.
What G2 users dislike about BookYourData:

"BookYourData’s pricing can feel high for smaller businesses or startups, especially for extensive or specialized contact lists. While the data accuracy is generally reliable, there are occasional outdated or inaccurate entries that may require manual verification."

10. Success.ai

Success.ai stood out to me for its intelligent automation tools, which streamlined lead generation and outreach. The system handled much of the heavy lifting, making it easier for me to connect with potential customers while keeping engagement high. The automation felt seamless, reducing the time spent on repetitive tasks and allowing a sharper focus on strategic outreach.

I appreciated the customization options, which made it easy to tailor campaigns to match the unique needs of different audiences. Success.ai provided a level of flexibility that was particularly valuable for adjusting messaging, refining targeting, and optimizing workflows. Collaborating with industry professionals, I saw how this feature helped users create highly personalized interactions that improved response rates.

The ease of integration and navigation made my overall experience smooth. Whether setting up workflows or using built-in features, the platform was intuitive, requiring minimal onboarding time. Users from different backgrounds could adopt the tool quickly, which speaks to its accessibility and user-friendly design.

That said, I experienced that the AI-generated email suggestions occasionally felt templated. While it did help maintain a steady flow of outreach, they sometimes lacked a natural touch. 

Additionally, while the email finder tool maintained a solid accuracy rate (~85%), I noticed some outdated company data in my tests. This aligned with insights from other G2 users, who suggested improving data freshness to enhance reliability.

The Chrome extension was a strong asset, simplifying contact discovery. However, the API occasionally slowed down during peak hours. Industry professionals I worked with found the extension useful but noted that optimizing API performance could enhance the tool’s responsiveness in high-demand situations.

Overall, Success.ai offers an efficient, customizable platform for lead generation and outreach.

What I like about Success.ai:

  • Success.ai’s intelligent automation tools streamlined lead generation and outreach, reducing time spent on repetitive tasks while improving engagement. The system’s customization options allowed for tailored campaigns, making it easy to refine messaging, target the right audience, and optimize workflows.
  • The platform’s ease of integration and intuitive navigation made adoption seamless, requiring minimal onboarding time. Additionally, the Chrome extension simplified contact discovery, making outreach more efficient.

What I dislike about Success.ai:
  • The AI-generated email suggestions occasionally felt templated, lacking a natural touch. While effective for maintaining outreach flow, they could benefit from more personalization.
  • The email finder tool had a solid accuracy rate (~85%), but I noticed some outdated company data. G2 users shared similar feedback, suggesting improvements in data freshness.
What G2 users dislike about Success.ai:

"Sometimes, the lead data from Success.ai can feel generic, and while the AI-generated email suggestions are helpful, they occasionally sound templated. However, with more granular targeting, Success.ai could become an even more powerful tool for scaling outreach."
