SPF Checker

Find the SPF TXT record for a domain and review common policy signals. This does not replace a full mail-flow or deliverability diagnosis.

Direct answer

SPF Checker: answer first

Check a domain SPF record and review missing, duplicate, or broad SPF policy signals. Use the result as an observable public-signal check with stated limitations, not as an absolute guarantee.

Last updated

Check SPF

Enter a domain to check SPF.
Technical response details (optional)


What the results mean
A normal SPF policy starts with v=spf1. Broad mechanisms such as +all can be risky, while too many includes can hit SPF lookup limits.
How to use this tool
  1. Enter the organizational domain.
  2. Review whether exactly one SPF record exists.
  3. Check DMARC after SPF so receiver policy is also visible.


FAQ
Does SPF stop spoofing by itself?
No. SPF is one signal. DMARC alignment and DKIM also matter.
Is ~all bad?
Not automatically. It is a soft-fail policy and may be intentional during rollout.
Can this validate every include?
No. This first pass highlights the root SPF record and obvious structure signals.

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.

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.

    Quick reference
    
SPF Checker: what this tool does

  
  

  

    
Finds SPF TXT records and highlights missing, duplicate, or broad SPF policy signals.

  

  

    

      
How to use

      
  1. Enter the sending domain.
  2. Check first that exactly one SPF TXT record exists: two is a hard failure at the receiver.
  3. Count the DNS lookups your includes will generate before you add another one.

    

    

      
What the result means

      
The result is the SPF TXT record published for that domain, read through /api/dns-lookup, with missing, duplicated and unusually broad policies flagged. SPF is a list of who may send for the domain; whether one message passes depends on the sending IP and the receiver's evaluation.

    

    

      
Limitations

      
  • Pass or fail is not decided here. SPF is evaluated per message against a real sending IP and envelope-from domain.
  • The record is read as published. Nested include and redirect chains are not expanded, so the ten-lookup limit is not counted for you.
  • SPF is one sender-authentication signal and is normally read alongside DKIM and DMARC rather than on its own.

    

  

  

    
More questions

    

      Does SPF alone protect email?
      
No. SPF is one sender-authentication signal and should usually be paired with DKIM and DMARC.

    

    

      What does SPF Checker do?
      
SPF Checker Finds SPF TXT records and highlights missing, duplicate, or broad SPF policy signals. Results are review signals with stated limits.

    

    

      How should I use SPF Checker 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 SPF Checker 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.
