Email
What is SPF?
A DNS record that lists which servers are allowed to send email as your domain.
SPF (Sender Policy Framework) is a TXT record in your DNS that declares exactly which mail servers may send email on behalf of your domain. Receiving servers check it before trusting mail that claims to come from you, which cuts both spoofing and accidental spam-foldering. Every domain that sends email should have an SPF record, and it must be updated whenever you add a new sending service such as a newsletter tool. Pair it with DKIM for the strongest deliverability.
