Know how the privacy-focused
email bounce checker works
We don't like email bounces. You don't like email bounces. So we've built the best privacy-focused bounce checker out there, so we can keep our open rates high and your response rate even higher. Our privacy-friendly email checker uses open source libraries to determine if an email bounced. Emails are not logged, not tracked. It's open source and you can host it as well
Step 1 : Regex and Typos
Blitzkrieg, thats the pace of the world around us, a few pattern and typo errors may occur, so we begin our checks here.
Step 2 : Disposable
Our second check is for those using burner emails, disposable emails, etc.
Step 3 : MX and SMTP
Finally, we get a tad more technical and perform the traditional Server checks.
