About Emails Checker

Who are we?

We once had a list of more than 1M emails, and our team worked hard to send an email to everyone on it. The open rate was only 1-2%. That was shocking, so we set out to understand what went wrong. After a lot of digging, we found our emails were fine but the main problem was the list itself. Around 60% of the addresses on it were temp mail (Disposable Email Addresses).

Most of our sending effort was going to disposable addresses. So we built a way to check an address in real time before it entered our mailing list, and the list grew healthier as a result. Then we decided to share that technology with other businesses.
