Email Health Check
Score your MX, SPF, DKIM and DMARC setup.
A combined email security baseline
The score combines receiving MX, SPF authorization, a DKIM selector when supplied and DMARC policy. It highlights public configuration risk but cannot predict inbox placement.
Frequently asked questions
Why does DKIM need a selector?
Selectors cannot be reliably enumerated. Copy one from your provider or a DKIM-Signature header.
Is 100/100 a delivery guarantee?
No. Reputation, content and recipient behavior still affect delivery.
Overview

Authentication is the foundation
