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.
