Email authentication, made easier to understand.

Speedmarc gives you a clearer view of the domains, senders, and DNS records behind your company email, so you can improve compliance with more confidence.

DMARC check

Check the current state of a domain.

Look up the published DMARC record, review the current policy, and see whether aggregate reporting is configured.

Run a DMARC check

_dmarc.example.com

v=DMARC1; p=none; rua=mailto:dmarc@example.com

Sender inventory

See who is sending email for your domain.

Review source IPs, header-from domains, SPF results, DKIM results, DMARC disposition, first seen dates, last seen dates, and observed volume.

DKIM selector rollups

Keep track of DKIM selectors.

Track observed DKIM domains and selectors so older keys, forgotten services, and selector changes are easier to review.

DNS snapshot

Review SPF, DMARC, and DKIM setup in one place.

Run DNS checks from a domain page, inspect the latest SPF and DMARC records, and see common DKIM selectors found during the check.

Compliance visibility

Make progress toward stronger email policy.

Use the authentication data mailbox providers expect: SPF, DKIM, DMARC alignment, and a clearer path from monitoring to stronger domain policy.

Recommended next step

Keep collecting reports until known senders align consistently, then review policy movement from none to quarantine.
