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.
