I have been using this tool for over 3 years and really happy with their services. But very recently the move to a fully premium based subscription this not a good decision at all. But working fine.

Bulk email checking future is not working properly they should fix this issue.

It's still a good email verification tool but not free anymore. It should be improved with the integration of the other email prediction and verification tools to be able to get reliable results. Now, it can provide 40-50 valid results but in the combination with other tools, it could be improved.

It's easy to use, you are getting results very fast.

It can't verify all the emails. Sometimes I am getting green results that mean the email is verified as valid but it's not. Sometimes the situation is different, you are getting a red result (not valid email) but that email is valid. It depends on the email hosting server. Some servers allow verification while the others can't.

Not good! Probably the worst experience on the whole!

The only thing that can be liked about Mailtester is its price. They have industry-best pricing. I, with my team, had been using MailTester from 2014; when it was free (though you could only verify one-by-one then). Then all of a sudden they made it PAID. We thought it's for good reasons, and as they had added BULK VERIFY then, we were happy to pay for it. And, the price of MailTester was very good, pretty perfect for us. But little did we know our result would fall. The valid ones started bouncing and sometimes MailTester would just break! Even after contacting their customer care, it would take days! SO, we had to switch. And we did switch. We still sometimes use MailTester, but for less important projects and, just as an optional verifier.

Mailtester's customer service is a nightmare!

Bulk verification is very impressive. It saves time & accurate for Email Campaign

Mailtester.com is very much effective for validating emails. It was highly accurate with the results. Can upload & validate bulk emails for sending mail campaigns

I like all the features offered in Mailtester.com

Mailtester has helped me a lot when it comes to verification of the contacts as it gives 90% accuracy on email testing.

Provides accurate data for most of the domains.

Doesn't shows invalid emails for few domains.
