Your email security grade, in seconds

When a client says they never got your email, your domain's setup is often the reason. Three DNS records decide whether your invoices land in the inbox or in spam. We'll grade all three, in plain English.

Free. No signup, no email address, no sales call. Your results appear on this page and nothing is stored.

Deliverability is only half of it. The same records stop fake invoices and payment-change scams sent in your name. And Gmail, Yahoo, and Outlook.com now filter harder against domains that fail these checks.

What you get

  1. Type your domain. That's the only thing we ask you for.
  2. Get a letter grade, plus a card for each of the three records showing what passed, what failed, and how to fix it.
  3. Hand the notes to whoever runs your email, or book 15 minutes with us and we'll walk through it.
Example only. This is a made-up domain, showing what your own results will look like.

Email from yourcompany.com can be forged, and your legitimate mail is being filtered harder than it should be.

DMARC

The policy that tells the world's mail servers what to do with email that fails SPF and DKIM.

FAIL

What this means: without DMARC, there is no instruction telling mail servers to block spoofed email claiming to be from yourcompany.com, even if SPF and DKIM are perfect.

  • No DMARC record found at _dmarc.yourcompany.com.

    How to fix it: publish a TXT record at _dmarc.yourcompany.com containing v=DMARC1; p=none; rua=mailto:you@yourcompany.com, read the reports for a few weeks, then tighten the policy to p=reject.

What are these checks?

SPF

Sender Policy Framework: a public list of the mail servers allowed to send email for your domain. Like a guest list at the door.

DKIM

DomainKeys Identified Mail: a tamper-proof digital signature added to every email you send. Like a wax seal on a letter.

DMARC

Domain-based Message Authentication, Reporting & Conformance: the rule that tells the world what to do with email that fails the first two checks. Deliver it, spam-folder it, or reject it.
