Start watching your domain

One email a week about who is sending as you, built from the DMARC reports mailbox providers already write about your domain.

Free for your first domain · 12+ months of history · No card

What arrives

On Monday morning, the share of your mail that passed DMARC, every source that failed, and any sender that has started using your domain since last week. When something needs doing, it says what.

What it costs

Nothing, for your first domain. It is not a trial and the free plan does not expire. We keep at least 12 months of report detail rather than cutting you back to a two-week window, and we do not meter how many messages you send. No card is asked for until you choose a paid plan. What the paid plans add, including SPF and DKIM Vision.

What setup takes

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

Nothing about your mail flow changes, and monitoring cannot cause a message to be rejected. Aggregate reports carry authentication results and message counts by sending server; message content is not part of the format.
