Behavior inside SendGrid
Removes a specific email address from the global unsubscribe/suppression list, re-enabling future sends to that address account-wide.
Request behavior and expectations
This only reverses global suppression specifically -- if that address is also separately listed in bounce or spam-report suppression, those are tracked independently and aren't cleared by this same call.
Implementation details
Removing someone from suppression should generally reflect an explicit resubscribe or a confirmed correction, since sending to a previously-unsubscribed address without that context risks both compliance issues and a fresh spam complaint that lands the address right back on a suppression list.
Use cases
Recover a previously suppressed address after consent or error correction.
- Re-enable a previously blocked contact when allowed.
- Update analytics to reflect suppression changes.
- Maintain audit trails for governance reviews.
- Coordinate with marketing teams on re-engagement timing.
