Game Changer If You Know How To Use It
First of all, I am sad to see some hate reviews. Don't know why they got such bad results - it demands an open debate where the founder of Mailverify should get a chance to prove them wrong with live demo.
I run a lead gen agency and I have been running client campaigns with Mailverify. Totally game changer for me, specially with the catch-all verification.
I know ins and outs of cold email and all the related tools out there. I've tested probably all the best ones, built my own AI Agent & stuff. I am loving Mailverify. And, knowing Alan & success of his other ventures - Mailverify is going to become a gem I'd love to boast of having a LTD of soon.

Spilling nonsense
It's just spilling nonsense, I have got not even 1 email right - tried with about 20 email addresses of mine, temporary ones and my client ones which I all know what these are, not even 1!! was identified right!!
Is it just guessing? I have no idea, but it's crazy. Too bad I have thrown away my $25 coupon on this. Go with Reoon!!

Full of Fake Claims - Very Disapointed
We have been testing their service for around 2 months. Initially this deal made us really excited as they were claiming to do some great stuff that the others were not offering. Cleaning up catch-all emails was one of them and it was one of the biggest reasons we purchased this deal. But that is a totally false claim.
The catch-all verifier is mostly a joke. Probably around 5% catch-all emails can get verified by their system with low accuracy. They still mark the other 95% as catch-all. Catch-all email verification is not easy, we all can understand that. But the way they were highlighting it made a lot of buyers believing and purchasing the deal only for that. Try verifying "support@appsumo.com" which is a valid email (they marks it as risky).
Temporary email verification is also not good. It can detect many older temporary emails, but cannot detect most of the latest temporary emails. Real spammers are not gonna use old temporary emails! So not much helpful.
Verification accuracy is not so good. They mark a higher number of emails as good, which is true. But we are also getting a higher number of hard bounces. They say on their homepage, "Other verifier ~50% deliverable, mailverify ~80% deliverable". But they won't tell you that you will probably get additional 50% bounces from that additional 30% (enough to kill your domain's reputation). It seems like they are not verifying all the parameters before marking an email as good to some some money here. This is a very bad practice. We do need higher number of good emails, but not at the cost of accuracy (higher bounces).
They cannot detect spamtrap emails at all. Our system got hit by many spamtraps in last 2 months. So, we won't rely on that either. Last week we tested it with 200 known spamtraps and the system marked about 14% of them as undeliverable and not a single one got marked as spamtrap.
Are there anything good about them? Yes, there are. The UI design is great. It's easy to understand the layout and it also looks great. Overall verification speed is good, no complaint on that. The credit limit is also good. The credit renews on time smoothly. Have not tested their API, but will probably work the same way.
If you are happy with extra bounces or just want to do an initial checkup, you can get the deal. However, if accuracy and low bounces are your first priority, then this deal is not for you. I will update my review if the situation changes in the future.

SO far so great!
This is super simple to use. I export my potential leads from my lead finder and drag the csv file into mailverify and it scrapes very quickly. 10,000 emails in a few minutes, then download to your computer. I just created the API key so I am going to play with this to see how I can integrate with my CRM.

It provides great insights into the features and benefits of MailVerify. You won’t regret your decision to give it a try!
I recently started using MailVerify for my email campaigns, and I must say, it has truly transformed how I manage my email lists!
The ability to validate addresses in bulk has saved me countless hours and significantly improved my email deliverability rates. Initially, I was skeptical about investing in an email verification tool, but MailVerify not only met my expectations; it exceeded them.
The user interface is incredibly intuitive, making it easy to upload lists and get results almost instantly. Plus, the accuracy of the verification process is stellar—my bounce rates have dropped dramatically since I started using it.
