Full of incorrect results and also skipping major checks
We have been using and testing this email verifier for some time now. Initially we were excited about this deal as it provides decent credits at a very reasonable price. Although there are many good things, as soon as we started our tests, we found some major flaws in their service. Let me share our experience with this service so that the AppSumo users can take their decisions based on that and hopefully they will be useful to the app owners also to improve their service.
1. One of the major issues with their service is full of inaccurate results. Especially the false negatives. It seems that if they cannot verify an address, they are just marking it as invalid. Bro, we can totally understand that you cannot verify each and every email because of the different kind of firewalls. If you cannot verify something, you should mark it as unknown, not invalid. In that way, we would at least know that the email was not verified and we can take our decision based on that. We would definitely prefer unknown instead of an incorrect invalid status. Are you doing this so that you do not have to refund the credits or just to make the results look better? Whatever it is, it is not a good practice.
2. They are marking any role emails as valid role emails even if it is invalid (or even if the domain does not exists). Probably it's a glitch/forgotten thing, but this glitch should not still be there after months of the app being live. We got a ton of hard bounces and almost got blocked because of that from one campaign.
3. They are also marking many many non-catch-all servers as catch-all. This is actually very dangerous as many marketers tend to send emails to the catch-all emails also (by taking a little risk). But treating non-catch-all as catch-all will result in serious harm to their IPs in such case. You are also marking yahoo, aol etc as catch-all, but clearly they are not catch-all. Please mark them as unknown instead if you cannot verify them or give us something so that we can understand the risks.
4. This app cannot detect spamtraps at all. Basically they do not provide the spamtrap detection feature. No email verifier can detect all spamtraps because of it's nature, but should atleast detect/block the known ones and flag the most likely ones. Hitting a spamtrap is 1000 times more dangerous than an email bounce. Without this detection, service is kind of useless for cold email marketers (however some people may not need this feature depending on the usecase).
5. They cannot detect any modern temporary emails. Just search in google for temporary emails and test the app with the first few google results. They can't detect the majority of them. However, they can detect old emails, which may not be as useful as anyone will naturally use the new ones from Google search.
6. We are not a fan of their maximum 5,000 emails per file limitation. Most of the serious marketers will have a larger email list than that. If I have a list of 50k emails, I definitely wouldn't want to split it into 10 files manually!
Now, let me talk about their positive things. The UI is kind of cool. It is easy to navigate and feels comfortable to use. Verification speed is decent (not very fast, but surely workable). They have API support available, which can be used to automate things. The credits they are offering are also very good at this price point.
Overall, at this point, we cannot use their service in our production environment because of the high risk, but we may keep the code in case the situation improves. We will do the tests again in the future and if they improve the service, I will update the review. Thanks.

Hey 👋 thanks for taking the time to share such a detailed review — we really appreciate the thoughtful breakdown. Feedback like this helps other users understand the tool better and gives us perspective on how different teams use it. To clarify a few things about how our system works:
1- You’re absolutely right, marking unverifiable emails as invalid instead of unknown can definitely cause...
I thought I would try EmailVerify with one code. My tests showed a good quality of verifications compared to another service that I have. It is advisable to double-verify your email list.
There were some missing features with EmailVerify so I booked a meeting with the founder. He added the features I was requesting within a week. I'm very pleased with EmailVerify and purchased more codes.

Thank you for sharing your experience! We’re thrilled to hear you found our verification quality impressive and that our team could quickly deliver the features you needed. We truly value feedback like yours—it helps us grow and serve you better.
We’re glad you’re enjoying EmailVerify and appreciate your trust in purchasing more codes. Looking forward to helping you keep your email lists clean...
Just started to test emailverify.io. There was a minor issue during signup: I didn´t receive the confirmation email, despite trying the resend function three times. I contacted emailverify.io-support via email and they solved my problem within a few minutes! Perfect! I´m building a proprietary lead manager app, and I use the API to connect and verify emails. My first test worked flawlessly. Emails get verified within seconds. So far, my experience is excellent. I hope that the verification results are of the same quality, which I cannot confirm at this time.
