Fantastic Email Validation Tool **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Professional Training & Coaching **Reviewed Date:** June 26, 2025 **What do you like best about ZeroBounce?** Having used other email validation tools in the past, I've been particularly impressed with the level of granularity in the details provided with ZeroBounce. With other software, the validation responses were extremely limited, but with ZeroBounce, we've been able to actually quantify spam traps that were affecting our database health. I also feel like we have a higher % of validation than we did with some other tools, where we saw extremely high volumes of unknown/unverifiable emails. **What do you dislike about ZeroBounce?** I love that ZeroBounce has the option to score catch all emails, but having to pay double for those contacts does add up over time. With some other tools, we only had to pay once to validate an email address (if it wound up in a future list), but with ZeroBounce, if you upload a contact that has already been validated, you will be charged each time. This requires some manual work to remove contacts we've recently validated so we don't re-pay for them in a short period of time. **What problems is ZeroBounce solving and how is that benefiting you?** We have had some pretty extreme database health issues, and the data we've received from ZeroBounce has allowed us to be very clear and confident with our recommendations on cleaning up our database and removing invalid contacts. **Official Response from Corina Leslie:** > Thanks so much for this detailed review. We're really glad to hear that the insights from our validation results have helped you improve your list! We hear you on the catch-all scoring costs and repeat validations. Our team is always exploring ways to make things more efficient for our users, and feedback like yours is very valuable. Thanks again for trusting ZeroBounce! ### 15. Does Exactly What You’d Hope – My Experience with ZeroBounce **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Information Technology and Services **Reviewed Date:** June 26, 2025 **What do you like best about ZeroBounce?** What I like best about ZeroBounce is that it just quietly gets on with the job. No faff, no fluff – it’s straightforward, does what it says on the tin, and keeps my email list clean as a whistle. The accuracy’s been spot on so far, and it’s saved me a right headache when it comes to bounces and spam traps. Proper useful bit of kit, really. **What do you dislike about ZeroBounce?** If I had to nitpick, I’d say the dashboard can feel a bit clunky at times – not the end of the world, but it could do with a bit of a tidy. **What problems is ZeroBounce solving and how is that benefiting you?** ZeroBounce helps me keep my email list in good nick by filtering out dodgy addresses – you know, the ones that bounce back, go nowhere, or land you in spam trouble. Before using it, I was wasting time and money sending emails into the void. Now, my deliverability’s much better, open rates are up, and I don’t have to worry about damaging my sender reputation. It’s taken a real weight off, to be honest. **Official Response from Corina Leslie:** > Thanks so much for your thoughtful review! We're glad ZeroBounce is doing exactly what you need it to. We'll pass your dashboard feedback along to our product team, too. It means a lot that you took the time to share this! ### 16.

Have loved using the tool the past two years. **What problems is ZeroBounce solving and how is that benefiting you?** ZB is allowing us to maintain healthy data in our CRM, which allows for better deliverability, higher open rates, and an overall healthier email reputation. **Official Response from Corina Leslie:** > Thank you for your review!

Easy way to clean email lists **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Retail **Reviewed Date:** November 20, 2025 **What do you like best about ZeroBounce?** I love how thorough ZeroBounce is when cleaning email lists, providing information not just on valid/invalid emails but often reasons why they are invalid. **What do you dislike about ZeroBounce?** The direct integration with Constant Contact doesn't seem much better (if at all) than just downloading then uploading the ZeroBounce results, I would prefer a more in depth integration with more options. **What problems is ZeroBounce solving and how is that benefiting you?** ZeroBounce helps us clean our large email lists to reduce bounces, spam reports, and bot clicks in our email marketing campaigns. **Official Response from Corina Leslie:** > Thank you for your review! We’re glad ZeroBounce’s detailed results make list cleaning easier and help you cut down on bounces and spam issues.

It was easy to integrate ZeroBounce into our processes. **What do you dislike about ZeroBounce?** I'm not sure I need the additional services like DMARC monitoring offered by ZeroBounce. Not a major issue, I just ignore the features I don't need. **What problems is ZeroBounce solving and how is that benefiting you?** Checking new email subscribers and new contacts via our website increases our trust in the data we're receiving. Periodically re-validating contact and subscriber information helps us keep our email lists up to date before we receive email bounces. **Official Response from Corina Leslie:** > Thank you for your review! We’re happy to hear ZeroBounce was easy to integrate and helps you keep your data accurate and up to date. It’s great to know our documentation and API have been useful in streamlining your process. ### 20. Spectacular Service! **Rating:** 5.0/5.0 stars **Reviewed by:** Jeff.
