Email DNS Checker — verify SPF, DMARC, MX

Email DNS Checker is a Navju Cloud tool for diagnosing email DNS settings. Available at tools.navjucloud.tj/email.

\n

What it checks

\n

    \n

  • MX — where the domain receives mail

    • \n

  • SPF — which servers may send mail on behalf of the domain

    • \n

  • DMARC — policy for messages that fail SPF/DKIM

    • \n

  • TXT — other records (including Google, Yandex verifications, etc.)

    • \n

\n

Why it matters

\n

Without correctly configured SPF and DMARC, mail from your domain ends up in spam or doesn’t arrive at all. This tool quickly shows what is set and what is missing.

\n

When to use

\n

    \n

  • Complaints about “mail isn’t arriving” or “going to spam”

    • \n

  • After changing your mail provider

    • \n

  • When configuring corporate mail on your own domain

    • \n

  • Before launching a campaign — confirm DMARC won’t break delivery

    • \n

\n

How to use

\n

    \n

  1. Enter the domain (no @, no mail prefix)

    2. \n

  2. Click “Check”

    3. \n

  3. The report lists found records and warnings about typical problems

    4. \n

\n

If you run mail on your own domain via Navju Cloud Hosting, ready-made SPF and DKIM values are issued in the panel. Copy them into your DNS zone and verify with this tool.
