For agencies and MSPs
Mailbox providers send your clients' domains a compressed XML report every day. We read them so nobody has to, and send one summary a week.
No account needed. We read public DNS only — nothing is sent to the domain and nothing is stored.
Sent every Tuesday — one email per domain, white label on the higher tier.
We publish the RFC 9990 authorisation record once, on our side.
Nothing for you to run, host or maintain.
$49 covers 100 domains. $99 covers all of them.
Gmail, Outlook and Yahoo send aggregate reports as compressed XML attachments: readable by machines, not by people.
Domain spoofing, or a legitimate sender quietly failing authentication, can go unnoticed for months.
An agency looking after 30 client domains receives hundreds of these files a week.
Add rua=mailto:<token>@checkdmarc.net to your
client's DMARC record. We give you the exact line to copy.
Reports arrive at that address and are parsed as they land. Nothing for you to run or maintain.
How much mail was sent, what share passed SPF and DKIM alignment, which sources are failing, and what changed since last week.
rua= line.
Competitors charge per domain. These prices do not.
Billing is monthly and handled by Polar as Merchant of Record. Cancel at any time from the customer portal; see the refund policy.
We process aggregate reports only (RFC 9990). We do not accept or
process failure reports (ruf, RFC 9991), which can contain message content
and recipient addresses. See the privacy policy.
The Service is run by one person and comes with no uptime guarantee — that is stated plainly in the terms, not buried. It is read-only in nature: it does not sit in the delivery path of your mail, so an outage here cannot cause mail to be lost or rejected. If something is broken, email support@checkdmarc.net and you will reach the person who wrote it.
