Works Great, Real Lifesaver! **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in E-Learning **Reviewed Date:** August 27, 2025 **What do you like best about ZeroBounce?** It filters out trash emails and little or no access emails. Cleaning up emails is essential, especially nowadays when it's hard to publish to those who truly want the information while not getting "dinked" on all the bogus emails. **What do you dislike about ZeroBounce?** I've been extremely happy. I really have to think hard to find anything wrong with it. With that said, there are a few emails without the last activity, but there are only a few. This could be user error (me). **What problems is ZeroBounce solving and how is that benefiting you?** My email list seems to have a lot of spam and low activity. I need a way to clean up these emails, especially now that broadcast proviers are becoming more and more strict. **Official Response from Corina Leslie:** > Thank you so much for the thoughtful review!

Good Tool, but Not Cheap **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Computer Software **Reviewed Date:** August 26, 2025 **What do you like best about ZeroBounce?** I like how accurate it is at cleaning email lists. It identifies invalid, abuse, and role-based emails, which has helped me cut down on bounce rates and improve deliverability. The detailed reports give me confidence that I’m sending to real inboxes, and that saves time and money in the long run. I also appreciate how fast it processes large lists, much quicker than I expected. **What do you dislike about ZeroBounce?** The biggest downside for me is the pricing. It can get expensive if you’re validating very large lists on a regular basis. Also, while the dashboard works fine, the user interface could be more modern and intuitive, it feels a little dated compared to other marketing tools I use. Lastly, no validator can perfectly handle catch-all addresses, and some still slip through, which can be frustrating at times. **What problems is ZeroBounce solving and how is that benefiting you?** ZeroBounce is helping me solve the problem of sending campaigns to bad or inactive email addresses. Before using it, I was dealing with high bounce rates, spam complaints, and the risk of damaging my sender reputation. Now, I can clean my lists with confidence and know that my emails are reaching real people. **Official Response from Corina Leslie:** > Thanks for the detailed review!

Effective and easy Automation **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Transportation/Trucking/Railroad **Reviewed Date:** September 05, 2025 **What do you like best about ZeroBounce?** ZeroBounce helped with automatically cleaning our email lists. We have API to import data into our email platform but we kept missing cleaning out lists. ZB helped streamline that process with some added perk tools like email checking and blacklist monitoring. **What do you dislike about ZeroBounce?** For review of how clean our lists are, it would be nice to have data or a dashboard of some sort to see what our average percent of valid vs. spam vs. invalid contacts we had over the course of the year but ZB doesn't retain our lists for that long nor does it have the option to look high level at that stuff from what we have. **What problems is ZeroBounce solving and how is that benefiting you?** It is helping our delivery rate which in turn helps our UOR. With email policy changes it turned our lead nurture upside down. We can now confidently send with cleaner lists and a stabilized delivery rate. **Official Response from Corina Leslie:** > Thank you for your detailed review! We’re so glad ZeroBounce has streamlined your list cleaning. We appreciate your feedback on having a high-level dashboard for year-over-year list quality.
