Frequently Asked Questions
What is SPF?
SPF (Sender Policy Framework) is a DNS record that lists which mail servers are authorized to send email for your domain. Receiving servers check SPF to verify the sender.
What happens if I don't have SPF?
Without SPF, anyone can send emails pretending to be from your domain. Many mail servers will reject or spam-folder such emails.
