About SPF Records
The SPF Record Lookup tool is a diagnostic tool that searches for and acts as an SPF validator for a Sender Policy Framework (SPF) record. It looks up the SPF record for the queried domain, displays it, and highlights errors that may impact email delivery.
SPF records let domain owners publish a list of IP addresses or subnets authorized to send email on their behalf. The goal is to reduce spam and fraud by making it harder for malicious senders to hide their identity.
Benefits of an SPF Record
- Email Security
Prevents spoofed emails from being sent on your domain.
- Deliverability
Reduces the risk of your emails landing in spam folders.
- Brand Protection
Protects your brand reputation and prevents phishing attacks.
- Traceability
You control which servers can send email on your behalf.
