Can someone send email as your business?
Type your domain and find out in seconds. This checks the same public records scammers look at, right here in your browser. Nothing is stored.
Checks SPF and DMARC (the records that stop email impersonation) plus your mail provider. Public information only.
How this works: your browser asks public DNS (via Cloudflare) for your domain's published email records. It's the same information any mail server, or any scammer, can already see. A "no DMARC" result means there is nothing stopping someone from sending email that looks like it came from you, the trick behind most fake-invoice and wire-transfer scams. The good news is it's a quick fix.
