Home / Free email security check
Free toolCan someone send email pretending to be you?
Enter your business domain. In about ten seconds you'll see whether the records that stop email spoofing are in place. It reads public records only and runs in your browser.
Public DNS records only. Nothing is stored or shared.
What the check looks at
Three records decide whether fake email from your domain gets delivered.
SPF
Who may send as you
A list of the services allowed to send email for your domain, like Microsoft 365 or your billing software.
DKIM
A signature on every message
Lets the receiver confirm a message really came from you and wasn't changed on the way.
DMARC
What to do with fakes
Tells other servers to deliver, quarantine or reject email that fails the checks. Only the last two protect you.
Why it matters
Fake invoices
The costliest business email scams start with a message that looks like it came from an executive or a vendor.
Need it fixed?
The Email Spoofing Fix sets up these records for the services agreed in scope, then reviews reports and legitimate mail flows before increasing DMARC enforcement. See what's included.
