What do these terms indicate?

  • Deliverable - these emails are safe to send
  • Undeliverable - these emails don’t exist and you should never send emails to any address with this status
  • Risky - behind this status you will find emails which are disposable, set up as Catch_all, or with a full mailbox. They may result in a bounce or low engagement
  • Unknown - Bouncer was unable to receive a response from the email provider, however, you will not be charged for this verification

🔔 Important: send cold email outreach campaigns only to "deliverable" email addresses, don't even try to use "catch all" and other types of emails.


Our Bouncer email validation test results

Ilya carried out an email validation test, involving a few campaigns with around 500 people in each campaign, and the results have come in! Let's look at the numbers.

We took emails from trustworthy sources which already high quality email addresses. The bounce rate with no email validation was... 8%:

Email validation results

Although it is not the highest bounce rate we ever received, it isn't negligible. If more cold email campaigns were to be sent out with an 8 to 12% bounce rate, the email reputation would definitely suffer some damage.

After email verification the bounce rate was... 1%.
