SPF (Sender Policy Framework) is an email authentication protocol that prevents unauthorized senders from sending emails on behalf of your domain. By validating the sending servers, SPF helps protect against spoofing and phishing.
This guide explains how to configure SPF for Kinsta, a managed WordPress hosting provider that often integrates with third-party email services to ensure secure and authenticated email delivery from your domain.
Kinsta does not support SPF alignment and will not authenticate SPF for DMARC authentication.
For Kinsta to work with DMARC you must use an SMTP service (such as Sendgrid, Mailgun and others) to relay the emails.
