Automatically identifying email addresses which bounce repeatedly and setting these records as Marketing Suspended is TRUE in your database will help protect your sender reputation.

 

Smart Campaign

Set Marketing Suspended to True - Hard Bounces

In this example, I am setting the Min. Number of Bounces to 5 in the past 90 days. If you send emails more often you might consider reducing the timeframe to the past 30 or 60 days.

Smart Campaign

Set Marketing Suspended to True - Soft Bounces

Using a separate smart campaign will allow you to set different Min. Number of Times and activity time frame. It also makes it easier to determine how many records flow through each campaign.
