Start watching your domain

One email a week naming the senders that use your domain, built from the DMARC reports mailbox providers already write about it.

What arrives

One email, Monday morning:

The share of your mail that passed DMARC
Every source that failed, named
Any sender that started using your domain since last week
When something needs doing, what to change

What it costs

First domain free. Not a trial; it does not expire
12+ months of report detail, not a two-week window
No volume metering: a million messages costs what a hundred does

The paid plans add realtime alerts, one digest across every domain, and the DNS cleanup. All of it is free to try for 14 days, no card.

What setup takes

Confirm this address, add your domain, publish one DMARC record. That record proves the domain is yours and asks receivers to send us their reports; the first one usually arrives a day or two later.

Nothing about your mail flow changes, and monitoring cannot cause a message to be rejected. Reports carry counts by sending server, never message content.
