# SPF

SPF (Sender Policy Framework) is an email authentication standard that helps verify whether the sender is authorized to send messages on behalf of a specific domain.

In EmailLabs, SPF is enabled by default. However, for the standard to function correctly, it is necessary to add the appropriate entry in the DNS TXT record.

**⬅️ Detailed instructions on how to configure the SPF standard can be found in the drop-down menu on the left.**
