Suppression lists

Ometria automatically suppresses a number of contacts when you create a broadcast campaign.

Contacts might be suppressed for any of the following reasons:

• Email addresses that hard bounce (i.e. the recipient server reports a permanent delivery failure).
• The email address is invalid - e.g. because of a typo in the address - which results in a hard bounce.
• You (the client) included the contact in a suppression list sent to us during your onboarding.

You can see how many contacts were suppressed per campaign by checking in Campaign performance: Broadcast campaigns

There are two kinds of suppression list:

• Your account suppression list - you provided this to us during your onboarding to Ometria.

• Ometria’s master list - this applies to all Ometria accounts. Contacts are added to the master suppression list automatically based on the factors described above.
