DMARCTrust

DMARCTrust is a DMARC monitoring tool from the team that built Mailjet. If you send email from your own domain, mailbox providers like Gmail and Microsoft are already sending you reports about who's using that domain, legitimately or not. Those reports are XML files almost no one reads.

We turn them into a clear dashboard: which senders are passing SPF and DKIM, which ones are failing, and whether anyone is spoofing you. You also get alerts when your DMARC, SPF, or DKIM records change unexpectedly. Setup takes a few minutes: point one DNS record at us and we handle the rest. EU and US hosting available.
