DomainSentinel

Scan. Detect. Fix.

We read SPF, DKIM, DMARC and MX for every domain you add, on a schedule. When something moves, we email you and show the fix.

Private beta, invite only

What it does

Point us at any domain. We read SPF, DKIM, DMARC and MX, and show what's broken.
Fix steps, with the record to paste where there is one.
DMARC aggregate XML upload, with a table of who sends mail as your domain.
Connect Google Postmaster Tools if you choose, and we add Gmail's spam rate and delivery statistics for the domains you have verified there.
Ask MARC, our assistant, about your own domains. It answers from your own scan data.

The beta is invite-only, and every beta user gets everything below, free.

Nobody is charged unless they choose a paid plan, and every beta user gets at least 30 days' email notice before the beta ends.
