Suppression lists can be used on a campaign or source to ensure that specific email addresses are not included in marketing efforts by your sources.

Note: It is considered best practice to only include emails that should never receive any marketing from your company under any circumstances. Generally, if someone opts out their email address, they do not need to be excluded from opting into a new campaign.

How To

Upload any size list of email addresses to ensure demand partners exclude them from your campaign. Suppression/unsubscribe lists can be added to any Email type field.

  1. From the Campaigns section of the main navigation, go to Lists.
  2. Select Create List and  choose  Suppression List.
  3. Create a name for the list.
  4. Check the MD5 box only if your suppression file is already encrypted as an MD5 file. If the file is NOT encrypted, be sure the box is not checked, otherwise Integrate cannot block the email addresses.
  5. Choose file to be uploaded.
  6. Select Create List.
  7. Once created, users can access the suppression list from any campaign or source for validating against the suppression list.
    1. From the Fields section of a campaign or source, add the Email field.
    2. Click the email field, and check the 'Suppression List' checkbox.
    3. Click the 'Assign A List' button, and choose the suppression list created in the previous steps.
    4. Alternatively, users can create a list on the fly within the campaign or source by choosing 'Create A List'.

Tip: You can use wildcard functionality here to suppress any general email address. For example, use “info@*” to suppress any email address that begins with info@. For additional examples, check below in the Fine Print section.

Fine Print

Wildcard functionality expanded:

With Suppression lists, a common use case would be wishing to block generic 'catch all' email addresses.  Let's walk through how to block an "" email address.

  • First, the piece we care about in this example is "info@", because it's the piece that will be constant.  In this scenario, "" is the portion we wish to create a wildcard for, so that any email address with "info@" would be blocked.
  • To do this, the email address we would enter into the suppression file would look like this: "info@*". By placing the * AFTER the info@, we ensure that any email address, from any domain which starts with "info@" will be suppressed.
  • Blocking any "sales" inboxes would be done the same way: "sales@*" would result in,, or being suppressed.
  • Example of a suppression file that would block various email prefixes:
