Email Deliverability Scanner.

Email is still the easiest way for attackers to pretend to be your business, fool your customers, and cause absolute chaos.

Without proper records like SPF, DKIM and DMARC, anyone can spoof your domain and send emails that look convincingly legitimate. The right authentication stops imposters at the door, protects your reputation, and keeps your messages landing where they should; in inboxes, not in the void.

What the tool checks.

We scan the key email security records that keep your domain safe, trusted, and deliverable.

SPF

Confirms which servers are allowed to send email for your domain, helping block spoofed or unauthorised messages.

DMARC

Sets rules for how suspicious emails should be handled, improving protection against spoofing and strengthening your domain’s trust.

DKIM

Adds a cryptographic signature to each email, proving it was genuinely sent from your domain and hasn’t been tampered with.

Understanding your results.

We use a simple traffic-light system to show how healthy your domain’s email security is:

Green

Your records are correctly set and your domain is well protected.

Amber

Your setup is partly correct but needs improvements to stay secure.

Red

Your records are missing or incorrect and require urgent attention.

Common issues when security measures aren't in place.

These are the problems we see most often when scanning domains, and they’re usually quick to fix once you know what’s going on.

Missing or weak DMARC.

DMARC is your domain’s defence line. Without it, or with a policy set too loosely, attackers can impersonate your email address and send spoofed messages that look convincingly real.

SPF errors.

SPF only works when it’s accurate. Old systems, forgotten services, or typos in the record can break it, making it harder for inboxes to trust your email (and easier for bad actors to exploit gaps).

DKIM not enabled.

If DKIM isn’t switched on, your emails aren’t digitally signed. That means mail providers can’t confirm they’re genuinely from you, which can lead to deliverability issues or message tampering.
