SPF Record Verification

Enter your SPF record to verify its syntax and configuration.

SPF Record Requirements

Syntax Rules

Version Tag

Must start with "v=spf1"

DNS Lookups

Maximum of 10 DNS lookups allowed

Record Length

Must not exceed 255 characters

Valid Mechanisms

Must use proper qualifiers and syntax

Best Practices

  • Always include an "all" mechanism as the last term
  • Avoid using "+all" as it allows any server to send mail
  • Start with restrictive mechanisms before broader ones
  • Keep DNS lookups well below the 10 lookup limit
  • Consider using "-all" for strict enforcement

Important: Incorrect SPF records can affect email deliverability. Test thoroughly before deployment.
