Can someone send email as you?
Can someone send email that looks exactly like yours? Type your web address or email address and see, in ten seconds, what every mail server checks before it trusts a message from you, in plain words.
What we read
Only your domain's public settings, the ones any mail server reads: whether fake email from your address is refused (DMARC), which services may send for you (SPF), the signatures on your email (DKIM), whether email to you travels encrypted (MTA-STS and TLS reporting), and who handles your mail. Nothing is sent to you and nothing is stored.
Why it matters
Without the right email settings, a fraudster can send an invoice from your exact address, and most mail servers deliver it. In France, 72% of monitored domains had no effective protection against fake email (DMARC) in September 2026 (DmarcDkim.com, Sep 2026).
What good looks like
Fake email from your address refused, every service that sends for you listed and signing your email, and email to you travelling encrypted. In technical terms: one SPF record ending in -all, a DKIM key for every service that sends for you, DMARC at p=reject after a few weeks of reports, and MTA-STS.
