What We Check

Four important signals that can damage authentication, reputation, and delivery.

SPF Record

Verifies only authorized servers can send email from your domain.

DMARC Policy

Tells inbox providers what to do with email that fails SPF/DKIM checks.

DKIM Keys

Cryptographically signs your email so providers know it's really from you.

Blocklist Status

Checks your mail server IP against 4 major spam blacklists.

Monitor It Automatically

One-time checks are fine. Knowing the moment something breaks is better.
