Sender Policy Framework (SPF) is an email authentication method designed to detect forging sender addresses during the delivery of the email. In this guide, you’ll learn:

  • What SPF records are
  • How to create and configure them
  • Why they matter for deliverability

​
What is an SPF Record?

An SPF record is a DNS TXT record that lists the mail servers allowed to send email on behalf of your domain.

​
Creating an SPF Record

  1. Log in to your DNS provider.
  2. Add a new TXT record with the value: 
    v=spf1 include:_spf.google.com ~all
  3. Save and propagate changes.

​
Why SPF Matters

SPF helps prevent spammers from sending messages with forged “From” addresses at your domain. This improves your deliverability and protects your brand.
