What is an SPF record?

An SPF (Sender Policy Framework) record is a type of DNS TXT record that lists authorized mail servers that are permitted to send email on behalf of your domain name.

Where should I add my SPF record?

You should publish your SPF record as a TXT record at the root domain level (@) in your DNS hosting provider (e.g. Cloudflare, Route53, GoDaddy).

How SPF Protects Your Email Domain

SPF works by allowing domain owners to declare which IP addresses and third-party services (such as Google Workspace, Salesforce, or Mailchimp) are authorized to send email on behalf of their domain.

Common SPF Qualifiers

~all (Soft Fail): Unlisted senders are accepted but flagged for scrutiny. (Recommended for starting).
-all (Hard Fail): Unlisted senders should be explicitly rejected by receiving mail servers.
?all (Neutral): No strict policy enforced for unlisted senders.
