Pros & Cons from Real Users

Pros

  • Apollo.io is very reliable and simple to use tool to identify the target POC in target company list. The details are very correct and help in connecting with the POCs faster. Integration with hubspot, email and linkedin helps in saving time and make the overall process very fast and efficient.
  • Apollo is great at what its primary use case is, creating, scheduling and sending outbound emails. We can get new campaigns set up quickly and utilize the A/B testing capabilities on a regular basis. It also shows good metrics around each of our campaigns
  • The sequence builder and email automation capabilities of Apollo work well and is the primary part of the application that we use. We have also tested the AB testing feature and this has helped improve our open rates by more than 10 percent.
  • Good and vast database. Great features like filters, export, sort, etc. Easy to use along with learning it.
  • UI, UX and Data are the main selling points. Starting with data, Apollo has one of the best enrichment systems out there, it integrates seamlessly with your LinkedIn to enrich the contact or business information of the page you're on. Apollo also works very nicely with your email, I am able to see recently opened emails and can also track recently sent emails as well as emails I can mark for follow-ups directly on my Gmail. Finally, the UI & UX system of Apollo is great, it's sleek and modern.

Cons

  • Sometimes the email ids are not correct and some profiles did not have contact numbers and that delays the process.
  • Sometimes the dataset isn't as large as what we can see in Linkedin for given roles/industries. At times it can appear slow to load data.
  • Often we can find contacts in Linkedin but are then unable to find them in Apollo so the quality of the data can sometimes be a bit hit or miss especially if you are targeting smaller companies and not just large publicly listed ones.
  • Slow at times, and Support is not that great, rest is fine.
  • Not a lot not to like about Apollo, I think external integrations that Apollo does not have might be an issue, so if you're deciding on Apollo you might have to do quite some heavy lifting switching.

Pros & Cons from Real Users

Pros

  • Our experience with VisitorsList has been excellent. The attendees data was up-to-date and genuinely helped improve our conversions. Their team is attentive, professional, and easy to work with. A dependable partner for event-driven campaigns.
  • VisitorsList made it much easier for me to keep track of incoming leads, monitor visitor activity, and organize both exhibitors and attendees data more efficiently. The interface is clean, the analytics load quickly, and the real-time notifications help me respond to new inquiries right away. I also liked that the setup was simple—I didn’t have to dig through complicated instructions to get things running. Overall, it genuinely saved me time and helped me understand my audience and event participants better.
  • VisitorsList.com specializes in providing B2B contact data from trade shows and events, with segmentation by industry, job title, and region. They offer free samples and customizable lists, allowing buyers to test data before committing. The company emphasizes GDPR and CAN-SPAM compliance, and third-party tools rate it as generally trustworthy. This focus on event-based data and verification can be useful for targeted marketing campaigns.

Cons

  • I’ve had a great experience using VisitorsList so far. Their attendees data has been accurate, easy to work with, and delivered exactly when I needed it. The platform feels intuitive, and their support team has been genuinely helpful whenever I had questions. It’s already adding value to my workflow, and I’m looking forward to exploring more of what they offer.
  • Although VisitorsList offers a solid range of features, I found myself wanting even more ways to explore the exhibitors and attendees data because the platform made it so easy to work with. It’s not really a drawback—more a sign that the tool is useful enough that you naturally want to do even more with it. I’m excited to see how the team continues to enhance the reporting and data options over time.
  • haven’t found any notable cons. The company appears professional, provides verified and customizable lists, and emphasizes legal compliance, making it a reliable option for B2B outreach.
