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
