Suppression
Addresses that are permanently excluded from every campaign.
Exclusion rules
| What happened | Result |
|---|---|
| Unsubscribed | Excluded forever |
| Reported as spam | Excluded forever |
| Mailbox does not exist | Excluded forever |
| Mailbox full / server busy | Can be contacted again |
| Our sending domain refused | Not the recipient’s fault |
- Permanent means permanent. Everything else stays contactable.
Where to find it
Applied automatically. You see the count in the review as “permanently excluded”.
How to do it
- Prepare a review of your campaign.
- Read the permanently excluded count.
- Continue: the exclusion is already applied to your plan.
What to expect
- Only three things exclude someone forever: they unsubscribed, they reported the email, or their mailbox is confirmed not to exist.
- A temporary problem — a full mailbox, a busy server, a technical failure on our side — never excludes a person.
- A message refused because of the sending domain is a sender problem and is never blamed on the recipient.
If it blocks you
Someone you know is fine appears excluded.
Contact support with the address. Exclusions are kept as a history, so a wrong one can be reversed without losing the record.
How it flows
- Unsubscribe
- Complaint
- Confirmed dead mailbox
- Permanently excluded
Unsubscribe always works
Every campaign email carries a working unsubscribe link, and an unsubscribe applies to all your future campaigns immediately.
