Is your domain protected — or wide open?
DMARC tells Gmail and Outlook what to do when something fails. Forward an email — we'll tell you in plain English.
Free DMARC Validator & Policy Checker
- What is a DMARC policy?
- DMARC tells receiving mailboxes what to do when an email fails SPF or DKIM checks — let it through, send it to spam, or reject it. It also protects your domain from being spoofed.
- Is DMARC required to reach the inbox?
- Since 2024, Gmail and Yahoo require DMARC for anyone sending in volume. Without it, your campaigns can be throttled or blocked outright.
- How do I validate my DMARC record?
- Forward an email and we read your DMARC policy from the live message, then explain in plain English whether it's set up correctly and what to change.
€9.99 for AI deep-dives.

You forward it.
Paste the mailbox above into the test-send field in Beehiiv, Kit, Substack, Mailchimp — or your own inbox. Hit go. We never see your subscriber list.

We actually open it.
In real Gmail, real Outlook, real Yahoo. We watch where your email lands — Primary, Promotions, or Spam — using the same filters that decide whether your campaign worked.

You get a report.
Plain English. Three things to change, in priority order. Unlock the bundle and we generate a subject, body, and CTA rewrite in your voice — paste them back into your campaign before lunch.
Two different tests.
Most people mix them up.
If you've ever searched "email tester," half the results check whether the address is valid. We do the other thing — whether the email itself will reach the inbox once you press send.

You upload a CSV of subscribers. The tool tells you which addresses bounce. Great for cleaning a stale list before a re-engagement send.
You forward one email — newsletter, launch, client note — to a one-time mailbox. We open it in real Gmail, Outlook, and Yahoo and tell you which tab it landed in, plus what to rewrite before you send it to your list.
We check whether your sends will land. That's the whole product.
Free to score. Pay only for the AI deep-dive.
Forward any email and get the score — free and unlimited. Buy credits when you want the occasional AI deep-dive, or go €9.99/mo if you send regularly. Cancel from the same screen you upgrade on.
