Why do emails bounce?

There are two main types of email bounces: soft bounces and hard bouncesThe inability to deliver an email message that’s caused by one or more permanent factors, such as an invalid email address..

Soft bounces mean it’s a temporary, fixable problem. Maybe your email newsletter is too large. Or the recipient’s email inbox is full. The server may also be down. Depending on the issue, a soft bounce can be easily fixed. If your email newsletter was too large, reducing its size could be all that’s needed for the email to go through.

Hard bounces are a permanent issue — and emails that hard bounce should be removed from your list. They can occur when an email address doesn’t really exist.

Maybe someone wanted to get the instant coupon code you were offering and submitted a fake email. Or someone accidentally made a typo when they entered their email.

People also change their email address over time and abandon their old one. They may have gotten married or changed jobs, which sometimes warrants a new email.

That’s why it’s so important to not only clean your list, but to do it regularly.

The consequence of inaction

Continually reaching out to emails that bounce comes with consequences. It can impact your sender reputation, which is like the credit score for your email address. The more you email non-existent email addresses, the more it hurts your score.

A poor sender reputation can impact your future email deliverability. To stay in good standing, aim for an email bounce rate of less than 2 percent. Anything more than that and there’s an underlying problem that needs to be addressed.
