DMARC monitoring: weekly SPF, DKIM and DMARC re-checks (early access)

By Keencrest · 2026-11-01

Not live yet. This is an early-access list for a service we plan to build. Nothing is running today, and joining costs nothing.

What we plan to offer

Weekly DMARC, SPF and DKIM monitoring for your domains: we re-check every week and email you when a record breaks or a new sender fails.

Weekly re-check of the SPF, DKIM and DMARC records for each domain, using the same checks as our free checker.
An email when a record disappears, changes, goes over the 10-lookup SPF limit, or a sender starts failing authentication.
Planned price: US$12 per month for up to 5 domains. That price is a plan, not an offer yet, and may change before launch.

Early-access list: no charge now

Email us your domains and we add you to the list. No charge now; we invoice only once the service launches, and only if you confirm you want it. You can leave the list by replying at any time.

Join the early-access list: email datagleaner@gmail.com (the message is pre-filled; add up to 5 domains).

What we need and what we do not

We need only domain names. We never ask for DNS, mail or hosting logins.
Monitoring reads public DNS records. It does not read your mail or your DMARC aggregate report files unless a later version says so.
No guarantee of delivery or inbox placement, and no legal or compliance advice.

Why monitor

Google and Yahoo publish requirements for bulk senders (SPF, DKIM and a DMARC policy, among others). Records that were right once can break when someone adds a new sending service or edits DNS. A weekly check catches that before a campaign goes out. Try the email header analyzer to see how one message authenticated, or run the free checker now.

We use the email addresses you send only to run this list and to contact you about it. To be removed, reply "remove".
