Ometria automatically suppresses a number of contacts when you create a broadcast or automation 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 or your colleagues included the contact in a suppression list sent to us during your onboarding.
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.
