# Suppress Multiple Prospects with a Suppression List

A suppression list omits prospects from list emails or engagement programs. Use suppression lists to prioritize engagement programs, prevent emailing prospects content that isn’t relevant to them, and to avoid emailing prospects too often. You can use any non-test list as a suppression list. Designate the list as a suppression list when building an email or engagement program.

Keep these considerations in mind when using suppression lists.

- A suppression list works well for suppressing prospects in bulk. To suppress an individual prospect, use the Do Not Email field on the prospect record.
- You can use a static or dynamic list as a suppression list. A static list doesn’t update automatically and is best for suppressing a specific set of prospects. If you want your suppression list to update automatically based on criteria that you define, use a dynamic list.
- List emails and engagement programs deduplicate recipient lists. If you select two or more lists for a list email or engagement program and the same prospect, the prospect receives only one email. Account Engagement also deduplicates when multiple prospects have the same email address on the lists. You don’t need a suppression list in this scenario.
- Sending the same email template again doesn’t automatically deduplicate the prospects from the previous sending. Building an engagement program with similar content to one that a prospect previously received doesn’t deduplicate the prospect. Use a suppression list in these scenarios.
- Prospects who are opted out or marked Do Not Email are suppressed from marketing emails by default.
- Emails that reference a deleted suppression list continue to treat the associated prospects as suppressed, meaning no emails are sent to them. To prevent this suppression in upcoming emails, the list must be manually removed from those specific emails.

- **[Create a Dynamic Suppression List](https://help.salesforce.com/s/articleView?id=mktg.pardot_segmentation_recency_and_frequency.htm&release=264.0.0&type=5)**  
    To prevent your customers from experiencing marketing fatigue, space out the timing of your emails with a suppression list. Create a dynamic list with a rule type that filters based on the recency and frequency of email sends.
