What Is an SPF Record?

SPF (Sender Policy Framework) is a DNS record that defines which mail servers are allowed to send emails on behalf of your domain.

It helps receiving servers verify that incoming emails are legitimate and not forged.

How SPF Protects Your Domain and Email Reputation

SPF plays a critical role in preventing email spoofing and improving deliverability.

When configured correctly, it tells email providers like Gmail and Outlook which sources are trusted to send messages from your domain.

When You Should Check Your SPF Record

  • Setting Up a New Email Provider
  • Troubleshooting Email Deliverability Issues
  • Adding Multiple Sending Services
  • After Making DNS Changes

Common SPF Record Errors and How to Fix Them

Multiple SPF Records Found

Having more than one SPF record will break validation. SPF must be combined into a single record.

SPF Record Too Long (DNS Lookup Limit)

SPF allows a maximum of 10 DNS lookups. Exceeding this limit can cause failures.

Missing or Incorrect Include Mechanisms

Wrong or missing include statements can block legitimate senders.

Syntax Errors in SPF Record

Small formatting issues can invalidate the entire record.

SPF vs DKIM vs DMARC: What's the Difference?

SPF is only one part of email authentication.

DKIM verifies message integrity using cryptographic signatures, while DMARC defines how receiving servers should handle failed authentication.

Using all three together provides stronger protection.

How to Fix SPF Issues Detected by the Lookup Tool

After running the check, you can update your DNS settings based on the results.

Focus on:

  • consolidating multiple SPF records
  • reducing lookup count
  • correcting include mechanisms
  • removing invalid entries

An SPF record is a TXT record in your DNS that starts with "v=spf1" and includes rules defining which servers can send emails on behalf of your domain. A typical example looks like this: v=spf1 include:_spf.google.com include:mailgun.org ~all
