Business email test

Enter your company domain. We check MX, SPF, DKIM and DMARC and give you ready records to paste.

Start

We check only public DNS records, like any mail server does. We do not store the domain or the results. The test runs in your browser.

Result

How to read the result

  1. A grade from A to F

    Four records: MX, SPF, DKIM and DMARC.

  2. Ready records

    You paste them in your domain’s DNS panel, at the registrar or at your host.

  3. No DKIM found

    We check 24 common selectors. We check another selector in the extended report.

  4. The test changes nothing

    It reads only public DNS records.

Questions

Frequently asked questions

SPF, DKIM and DMARC after the Gmail changes (in Polish)
Why do my emails land in spam?

Most often because SPF, DKIM or DMARC is missing or wrong. Since 2024 Gmail and Yahoo check them on every message.

What are SPF, DKIM and DMARC?

They are three records in your domain. SPF lists the servers that may send mail from the domain. DKIM signs each message. DMARC tells the recipient what to do with an email that failed the checks.

Does the test change anything in my domain?

No. The test only reads public DNS records. We store nothing.

The test did not find DKIM, but I have it turned on. Why?

DKIM has a name (a selector) chosen by your email provider. We check the 24 most common ones. In the extended report we check the headers of a real message.

Where do I paste the records from the report?

In your domain’s DNS panel, e.g. home.pl, OVH, nazwa.pl or Cloudflare. Don’t know where your DNS is? We will do it for you.
