MX Lookup

Check a domain's mail exchanger records and see which hosts receive mail for that domain. This is a DNS record check, not a full email-deliverability audit.

Direct answer

MX Lookup: answer first

Check MX records for a domain and see mail exchanger priority and hostnames. Use the result as an observable public-signal check with stated limitations, not as an absolute guarantee.

Technical response details (optional)

    

    

      
What the results mean
MX records list mail servers and priorities. Lower priority numbers are tried first. Missing MX records may mean the domain does not receive mail or relies on a provider-specific setup.
How to use this tool
  1. Enter a domain name.
  2. Review each mail exchanger host and priority.
  3. Check SPF and DMARC next if you are reviewing email authentication.

      
    

    
FAQ
Can MX records be hidden?
Public mail routing generally needs public MX records, though some domains intentionally receive no mail.
Why do multiple MX records exist?
Multiple records can provide priority ordering and fallback mail delivery paths.
Does this check DKIM?
No. DKIM records vary by selector. Use DNS Lookup if you know the selector.

Client-safe copyClient-safe copy should keep authentication findings and fixes while removing email local-parts, raw TXT payloads, raw sender IP details, and private mailbox context.

    
Monitoring beta (optional)Optional monitoring beta can compare MX, SPF, DKIM selector checks, DMARC policy, PTR/rDNS, and selected blacklist signals for approved domains.

Share findings without leaking raw technical material

      
Use Safe Copy or this page's summary when sending results to a client, vendor, developer, or support team. Raw headers, credentials, tokens, cookies, private addresses, email local-parts, and oversized payloads should stay out of client-facing copy.

MX Lookup: what this tool does

    
Checks public MX records and shows mail exchanger priority and hostnames.

  

  

    

      
How to use

      
  1. Enter one public domain, email domain, optional selector, or pasted header depending on the tool.
  2. Review authentication, policy strength, routing, and monitoring signals together.
  3. Apply one DNS or mail-provider change, then retest after propagation.

    

    

      
What the result means

      
Treat MX, SPF, DKIM, DMARC, MTA-STS, TLS-RPT, PTR, and header findings as email trust signals. They do not guarantee inbox placement or prove sender identity alone.

    

    

      
Limitations

      
  • This tool reports observable signals only; it is not a guarantee or certification.
  • Uses /api/dns-lookup with MX records through Cloudflare DoH.
  • Results can change after VPN reconnects, DNS propagation, browser updates, cache changes, or provider configuration changes.

    

  

  

    
FAQ

    

      Does an MX record prove email is configured correctly?
      
No. MX records show mail routing targets, but mailbox, SPF, DKIM, DMARC, and provider settings also matter.

    

    

      What does MX Lookup do?
      
MX Lookup checks public MX records and shows mail exchanger priority and hostnames. Results are review signals with stated limits.

    

    

      How should I use MX Lookup results?
      
Use the result to decide what to review next, make one change at a time, and retest in the same browser, network, domain, or provider context when possible.

    

    

      What does MX Lookup not prove?
      
It does not prove anonymity, full security, complete deliverability, full reputation cleanliness, search ranking, or AI citation. It only reports the visible signals available to this tool.
