How fast should FBL complaints be processed?

FBL complaints should be processed as quickly as possible, ideally within hours of receipt. The complaining address must be suppressed before your next send to prevent repeat complaints that compound reputation damage.

Automated processing is essential for high volume senders. Manual complaint handling cannot keep pace with sending frequency. Systems should ingest FBL reports and add addresses to suppression lists automatically.

Some organizations set target processing windows of under 24 hours. However, if you send daily, processing complaints the next day means one more message to someone who already complained. Real time or near real time processing is better practice.
