Bounced Emails

When viewing your reporting data for campaigns or automations, at some point you'll see a percentage of Bounced emails.

Anytime an email bounces, that means that the email was rejected by the receiving server. 

There are two types of bounced emails:

Your bounce rate is a big part of overall deliverability. Continuously sending to email addresses that bounce can negatively affect your sender reputation, so your goal should be to keep this number as low as possible.

Hard Bounces

A hard bounce means that the email cannot be delivered for a permanent reason, for example: 

  • the email address is fake or misspelled
  • the domain does not exist
  • the recipient is not accepting emails
  • the account has been closed 

Contacts within your account that have registered as a hard bounce will immediately be added to your suppression list so they cannot be sent another email.

Soft Bounces

A soft bounce means that the email cannot be delivered for a temporary reason, for example:

  • the receivers inbox is full
  • the email is too large
  • the receiving server is experiencing delays or is offline 

We will continue trying to deliver to a soft-bounced contact a few times before it is considered a hard-bounce and added to suppression.
