Sender Policy Framework (SPF)


What is SPF?

Sender Policy Framework (SPF) is an email validation system which aims at reducing spam by ensuring that emails are being sent from valid IPs. Domain administrators simply specify which hosts/IPs are allowed to send email by creating SPF (TXT) DNS records.

How do I set it up?

  1. Open spfwizard.net
  2. Follow the steps to generate the SPF DNS entry; copy it to your clipboard
  3. Whichever company manages your DNS (typically your domain registrar):
    • Either log in and add an SPF or TXT record that contains the text you copied in Step 2
    • Or if you’re unsure how to do this, contact your domain registrar
