RUNBOOK · sender/account-suspended4 FIXES

// quick answer

Sender suspends accounts that exceed its anti-spam thresholds (0.15% complaints, 5% bounces, 1% unsubscribes) or send prohibited content. Read the reason in the suspension email, clean the list, then appeal via LiveChat or support@sender.net with proof of opt-in.
