What Is an SPF Record?

Your email might look fine. Filters don't see it that way.

What is an SPF record?

An SPF record is a DNS TXT record that defines which mail servers are authorized to send emails on behalf of your domain.

How it’s checked

When a receiving server gets an email from your domain, it looks up your SPF record. If the sending server isn’t authorized, the email fails authentication.

Why it affects inboxing

Failed authentication reduces trust and can push emails into spam. SPF is a baseline for deliverability and security.

// Example - spam trigger words to avoid

Definition
