Using a reliable email validation service is at the core of good email deliverability. Finding one, though, can be tough when there are so many platforms to choose from. If you’re trying to decide between ZeroBounce and MailTester, we’ve got some helpful information for you.

To see how the two services compare, we researched the differences, and here’s what we found.

While MailTester’s pricing is lower than ZeroBounce’s, the old adage “you get what you pay for” applies. For starters, MailTester does not offer 24/7 customer support, so if any issues occur while you clean your list, you may have to wait a while until you can get someone to assist you.

Also, as opposed to ZeroBounce, MailTester cannot detect abuse emails belonging to known complainers. Moreover, the service does not identify catch-all domains, nor does it append any missing data to your list.

MailTester claims it provides 99% accurate email verification results. However, the company does not disclose whether it offers a money-back guarantee.
