Permanently deletes the suppression record, so Bird delivers to the address again. Deletion cannot be undone; if the address hard-bounces or the recipient complains again, a new suppression is created automatically. Remove a suppression only when you are confident the address is deliverable and opted in: most records exist because the address bounced, complained, or unsubscribed, and sending to it again harms your sender reputation. An address suppressed for several reasons has one record per reason; delete each blocking record to re-enable delivery. To find a record by address, use GET /v1/email/suppressions with the `email` parameter. An ID that does not exist in the workspace returns `404`.
