Stop criminals sending emails as you
SPF, DKIM and DMARC decide whether anyone can pretend to be your company. We set them up properly, so your emails land in inboxes and your name stays yours.
Why your domain needs protecting
Anyone can type your company name into the From field of an email. Without the right settings, nothing stops it.
Fake invoices
Criminals email your customers or staff pretending to be you, asking for payment.
Emails going to spam
Poor settings mean genuine emails from you can be marked as junk.
Your reputation
Customers trust your name. Domain protection helps keep it that way.

The three settings that matter
Explained without the jargon.
SPF
A list of the servers allowed to send email for your domain.
DKIM
A digital signature that proves an email really came from you and was not changed on the way.
DMARC
The rule that tells receiving servers what to do with emails that fail the other two checks, and reports who is sending as you.
Questions we get asked
What are SPF, DKIM and DMARC?
Three email settings that work together to prove who is allowed to send email from your domain and what should happen to fakes.
Will changing them break my email?
Done carelessly, it can. We check every service that sends email for you first and bring the rules in step by step.
Do I need this if I use Microsoft 365?
Yes. Microsoft 365 provides the tools, but the settings for your own domain still need to be configured correctly. Microsoft 365 support →
Is the domain check really free?
Yes, and it changes nothing on your systems. It reads public information about your domain.
What if the check finds problems?
We will explain what they mean in plain English and, if you want, fix them for you. Talk to us →
