Frequently asked questions

Quick answers for business owners — fake email, your domain check, and how to protect your business.

What does Email Trust Check do?

We show whether scammers can abuse your domain in email — with a letter grade and checklist you can act on or forward to whoever manages your domain.

Is the check free?

Yes — built for business owners. No account required.

Do you send email or access my inbox?

No. We only look at public domain settings. Your inbox stays private.

How long does a check take?

Usually a few seconds.

What is a good grade?

A or B means your customers are well protected. C means some gaps remain. D or F means urgent exposure — often missing the policy that blocks fake mail.

What is SPF?

A DNS list of servers allowed to send mail for your domain. See our SPF guide for details.

What is DKIM?

A digital signature proving mail was not tampered with. Keys live in DNS.

What is DMARC?

A policy telling receivers what to do when authentication fails — the main tool to block fakes.

Does BIMI affect my grade?

No. BIMI is optional brand display in some inboxes.

We use Google Workspace — are we protected?

Google helps with sending, but you still need SPF, DKIM, and DMARC in DNS for your domain.

Can I fix DNS myself?

If you manage DNS, yes. Otherwise forward our report to your IT provider or registrar.

How often should I re-check?

After any DNS change and at least quarterly.

Will this stop all phishing?

It reduces domain spoofing significantly. Staff training still matters for look-alike domains and compromised accounts.

What if my domain is new?

New domains are often unprotected until someone sets up the three core protections — check early so scammers don't get a head start on your name.

Can I embed the tool on my site?

Yes — use /embed/check or ask your developer for the iframe snippet on the dev hub.

Do you sell my email or share it with advertisers?

No. We use your email to deliver the report you asked for and optional tips only if you opt in. See our Privacy Policy for details.

What data do you collect when I run a check?

For a basic check, we query public DNS for the domain you enter. If you request a report, we also store your work email and scan summary to send the report. We do not access your inbox.
