SPF (Sender Policy Framework) is a security measure implemented to protect against fake emails. It allows you to specify which systems or providers (e.g. GatewayAPI) that are allowed to send emails on behalf of your domain.

Specifically, when you use SPF, you create a list in your domain’s DNS of the servers that are allowed to send emails from your domain. Once you have set up SPF correctly, the recipient’s server can check whether the email actually comes from an approved source.

GatewayAPI supports both DKIM and SPF as standard in our email service, as both technologies increase the delivery rate and protect against forged sender addresses.

Without SPF, malicious actors can send emails that appear to come from you. In addition, a correct SPF configuration improves the credibility of your emails and minimizes the risk of ending up in spam.

If you send emails through GatewayAPI, you should update your SPF record in DNS to include our systems. You can do this by adding include:_spf.gatewayapi.com to your SPF record. You can read more about how to set this up correctly in our email documentation.
