Prove your email security, where your customers can see it
The DMARCER Trust Mark is a small badge that shows your domain's live, independently-scored email-security posture. Put it on your site or in your signature, and anyone can verify it for themselves.
A clear grade anyone understands at a glance
Always your current posture, never a stale claim
One click to confirm the score is genuine
Good security is worth showing
You have done the work to lock down your email: authentication in place, DMARC at enforcement, transport encrypted. The problem is that none of it is visible. A customer deciding whether to trust an invoice, a supplier weighing you up, a visitor about to hand over their details, none of them can see any of it. The most trustworthy domains look exactly like the least.
The DMARCER Trust Mark turns that invisible posture into a badge you can show. It reports your domain’s current email-security grade, scored independently by DMARCER against the same checks we run across whole industries, so a claim of “we take security seriously” becomes something a visitor can actually see and confirm.
Why this matters, whoever you are
- It makes your security posture a visible asset, not a private one.
- Running your own domains? A verifiable grade builds confidence with customers and partners.
- Managing clients? A badge on each client’s site is proof of the value you deliver, renewed automatically as their posture changes.
How it works: scored, shown, verifiable
DMARCER scores your domain, renders the result as a small badge, and gives anyone who sees it a way to confirm it is real. The score is never something you type in yourself, which is exactly what makes it worth trusting.
Scored independently
DMARCER grades your domain against the full stack of email-security controls, the same checks behind our industry benchmarks. You can’t inflate it, which is the point.
Shown as a badge
A clean shield with your grade, score and the date it was checked. Drop it on your website footer, a trust page, or an email signature.
Verifiable in a click
The badge links to a live verification page on DMARCER, so anyone can confirm the grade is genuine and current rather than a picture you pasted in.
One line to add it
Once you enable the Trust Mark for a domain in your DMARCER account, adding it to your site is a single snippet. It stays current on its own: as your posture improves, the badge updates, with nothing for you to redo.
Prefer not to show a grade until it is where you want it? The badge is yours to switch on and off in a click, so you publish it on your terms.
Embed snippet
First enrol your domain and enable its Trust Mark in your DMARCER account. Once it's enabled, add this snippet where you want the badge to appear:
<script src="https://trust.dmarcer.net/badge.js" async></script>
We use it on our own site: the badge in the footer is a live DMARCER Trust Mark for dmarcer.net.
