The difference between a hard bounce and soft bounce is:

A hard bounce is a permanent reason an email cannot be delivered. Hard bounced email addresses will be excluded from emails sent via itracMarketer. Below are some general reasons why this could happen:

  • The recipients email address does not exist.
  • The domain name does not exist.
  • The recipients email server has completely blocked delivery.

Soft bounces typically indicate a temporary delivery issue to an address. itracMarketer will continue to try to send to these email addresses. Below are some general reasons why this could happen:

  • Mailbox is full.
  • Recipient email server is down or offline.
  • Email message is too large.
