SPF/DMARC Email Deliverability Check
Check whether your domain has the basic SPF, DMARC and mail-routing records that stop invoices, contact-form replies and client emails from getting lost or spoofed.
This is a quick first-pass diagnostic for domains that may have weak email authentication or incomplete DNS setup.
It does not replace a full deliverability review, but it quickly shows whether the most common SPF, DMARC and MX basics are missing or weak.
Run the check
Quick check for SPF, DMARC and basic mail-routing signals. Enter only the domain name, for example example.com.
What this check does
- Checks whether the domain publishes MX records at all.
- Looks for a public SPF record on the root domain.
- Looks for a DMARC policy on `_dmarc.yourdomain` and flags weak `p=none` setups.
- Shows whether the domain appears to be missing the most common email-authentication basics.
Important limits
- It does not test inbox placement or reputation across mail providers.
- It does not verify DKIM selectors in this first version.
- It does not validate provider-specific edge cases or forwarding setups.
- For production mail problems, a full DNS and mail-flow review is still the right next step.
Need the records fixed properly?
If business mail is already disappearing, the safer path is to review the DNS zone, provider setup, MX path, SPF alignment and DMARC policy directly instead of guessing from partial symptoms.
Practical support for VPS, hosting, domains, DNS, email routing, SSL, migrations and unclear access or responsibility.
Direct help for broken forms, failed deployments, unstable pages, integration issues and inherited website setups.
