Suped email authentication and deliverability handbook set

DMARC

Monitor who sends email for your domain, understand policies, and move toward enforcement with fewer false positives.

SPF

Learn how SPF authorizes sending infrastructure and why lookup limits, includes, and alignment matter.

DKIM

Understand selectors, signing keys, rotation, and how DKIM proves that a message has not been altered.

BIMI

See how verified brand logos work on top of strong DMARC enforcement and the records required to publish them.

MTA-STS

Learn how policy files and TLS reporting help protect mail delivery between servers.

Blocklists

Track the reputation lists that can stop mail from reaching the inbox and learn how delisting works.

Email deliverability

Connect authentication, reputation, sending behavior, and mailbox placement into one practical operating model.

DMARC for MSPs
