Email deliverability score: why do my emails go to spam?

Get one score out of 100 for your email domain. We check mail servers, SPF, DKIM, DMARC, reverse DNS, MTA-STS, TLS reports and BIMI, and tell you what to fix first, in simple words.

This tool needs JavaScript. Please turn it on, or open the page in a current browser.

How to use this tool

  1. Enter your domain Type the domain you send email from, or any address on it.
  2. Get your score Click “Get my score”. Checks run in your browser using public DNS.
  3. Read the score See your score out of 100 and a one-line summary.
  4. Fix red items first Red items hurt the most. Each one says what to do.
  5. Check again After changing DNS, wait a little and check again to see the new score.

Most important

  • SPF, DKIM and DMARC carry most of the score.
  • Gmail and Yahoo expect all three from bulk senders.
  • Your mail server needs a reverse DNS name.

Nice to have

  • MTA-STS and TLS reports protect mail in transit.
  • BIMI can show your logo, after DMARC is enforced.
  • These add points but are optional.

Beyond DNS

  • Clean lists: remove bounced addresses.
  • Send what people signed up for; avoid spammy words and too many links.
  • Warm up new domains slowly.

Questions about this tool

Is 100 needed?

No. Above 85 is excellent. Optional items like BIMI are not needed for good delivery.

Does a good score promise inbox delivery?

No. Content, reputation and list quality also matter. A good score removes technical reasons for spam.

Why is DKIM yellow?

We could not find a key with common selectors. Enter your selector from your email admin panel.

What about blacklists?

Blacklist checks need our server and will be part of the live version. Use our Blacklist lookup tool too.

Is my domain sent to your server?

No. The checks use public DNS from your browser.
