Authentication

A letter grade for your email, in about a minute

We read the public records that decide whether your mail reaches the inbox or the spam folder, and tell you what is wrong in words you can act on.

No account needed for your first check. We read public DNS only, never your inbox.

Free, no account. The card below becomes yours.

Mostly healthy. One record is letting you down.

✓SPF — published and valid, 4 of 10 lookups used

✓DKIM — signing key found on selector google

!DMARC — policy is p=none, so nothing is enforced

✓Not on any major blocklist

An example report card. Yours is generated live from your own DNS.

What you get

The parts that matter, without the marketing.

The three records that prove your mail is really yours. We say which are missing and exactly what to publish.

Every problem comes with the record to copy. No searching for what the syntax should be.

Check your own, or a supplier's before you trust an invoice from them.

Three steps. Nothing to install.

The address your business sends from. Nothing to install.

A to F, with the reasoning underneath in ordinary language.

Paste the record into your DNS, or hand the page to whoever runs it.
