Does your email
actually arrive?

Type a domain. In about a second you get SPF, DKIM, DMARC and MX checked, plus the exact records to add and where to add them.

We read public DNS only. No password, no access to your inbox.

Since February 2024

Gmail and Yahoo reject mail without SPF or DKIM, and require DMARC from anyone sending over 5,000 a day.

Three records

Most fixes are two or three TXT records in DNS. The report gives you the values to paste.

Rechecked in 7 days

Get the report and we check the same domain again a week later, then tell you what changed.

What you get

  1. Results on the spot

    The score and every problem show on screen. No signup, no waiting.

  2. Report PDF and guide

    Confirm your email once and both land in your inbox. Forward them as they are to whoever runs your DNS.

  3. A review by a person

    Leave your details and the report goes out at once. What DNS cannot show, we check by hand and come back.

Hands-on review · free

The report now, a person right after

Ask and the report PDF and guide go straight to your inbox — no waiting. Then we look at what public DNS cannot show and come back to you.

The part a person does usually comes back within two business days.

All of that is free.

Straight answers

Is this really free?

Yes. The check, the report PDF and the hands-on review all cost nothing. It is how we show the way we work. One thing costs money: the hour where we sit down and finish it with you, US$399 — and you only book that after reading the report.

Where does my domain data go?

The check reads public DNS, the same records anyone in the world can look up. Your domain and email are used for the report and the 7-day recheck, and are never sold or passed on.

What do I need to install?

Nothing. Type the domain name and the result is there in about a second.

What if everything passes?

Then there is nothing to do today. DNS changes quietly, though: add a sending service or rotate a key and it can start leaking that day. We check again after a week and tell you.

Can I fix it myself?

Usually it is two or three TXT records, about thirty minutes. The report names the screen to open and the value to paste.
