Suppression List

Also: Do-Not-Contact List

A list of addresses you must never email, unsubscribes, complainers, bounces, and do-not-contact requests, enforced automatically across your sending.

Why it matters

Honoring suppression is both a legal requirement and a reputation safeguard; emailing someone who opted out risks complaints, compliance breaches, and damaged deliverability.

What good looks like

A working suppression list is centralized, applied automatically to every send, and includes unsubscribes, hard bounces, complaints, and explicit do-not-contact requests.
