What we'll check

Start with the external signals that matter most.

Email

SPF, DKIM and DMARC: whether your domain has the authentication controls that matter for sender trust and deliverability.

Website

HTTPS, security headers and public website posture visible from outside your network.

TLS

Certificate validity, expiry and HTTPS configuration for your public website.

DNS

Domain and DNS configuration signals visible to anyone outside your organisation.

Email sender readiness

Google, Yahoo and Microsoft have tightened email authentication requirements.

High-volume senders now need SPF, DKIM and DMARC, while every business domain benefits from properly configured email authentication for deliverability and spoofing protection. The free preview shows where your domain stands today.
