Score a real email
Checking a domain’s DNS tells you what could happen. This tells you what actually happens to the message you send: the DKIM signature is verified against that exact body, the SPF against the IP that really delivered it, and the whole thing goes through a real spam engine.
We give you a one-off address. Send your email there — from your newsletter tool, your app, your server, whatever you actually use — and the report appears here on its own.
Free: a few tests a day; the address is short-lived.
