Problems with your email?
Landing in spam? Getting marked as suspicious? Worried someone could send fake emails in your name? It usually comes down to one thing — whether the world can tell your email really comes from you. Enter your domain and find out in seconds, in plain words.

The check above is a snapshot. Monitoring watches for you.
Add a domain and DMARC Viewer reads the daily reports mail providers send, turns them into a plain-language picture of who is sending as you, and emails you the moment something changes.
Who is sending as your domain
⚠ Example alarm
A new source started sending as your domain. An unrecognised server sent 240 messages as you in the last 24 hours, all failing authentication — a sign of spoofing, or a service you forgot to set up.
You’d get this as an email the day it happened — not weeks later.
Who acts on this? Usually you or your IT provider. DMARC Viewer tells you which sender to look at and what to change — you don’t need to read the raw reports.
Check a real message
The instant check reads your public settings. Send us one real email — we read that exact message and show you how it arrived. One test reflects that message from that sender; mail you send from other systems may look different.
