Campaign Email Bounces
As with any email marketing campaign you will inevitably have some email addresses that will bounce. There are two types of bounces:
* Hard bounces are permanently unsubscribed. In order to re-subscribe a contact who has hard bounced you can update their email address.
* Soft bounces are unsubscribed/rested for 30 days. After 30 days they will automatically become resubscribed. Updating their email address allows you to re-subscribe them sooner. This protects your reputation and the Campus mail servers from bombarding bounced addresses with further marketing in a short amount of time.
