Email verification FAQ

Why should you only send to verified email addresses?

Non-verified emails cause more bounces. Bounces are bad for your sender reputation. If your sender reputation suffers, so does your email deliverability. In other words, email verification is important for long-term outreach success.

Do you have to use a tool to verify an email?

Yes, for bulk email lists. Otherwise, it would take too long. But there are other ways to verify an email.

Can I verify emails for free?

Yes, several of the tools listed above offer free monthly credits. Additionally, there are completely free tools available like our free email checker. However, for large lists, the only real solution is investing in an email verification tool.
