SPF (Sender Policy Framework) is an email-authentication technique, which allows the domain owner to control who can send messages on behalf of the domain.
DKIM (DomainKeys Identified Mail) is an email-authentication method, which ensures that message's subject, sender address or content has not been tampered with during transit.
Properly set up SPF and DKIM signal the recipient's mail server that the message is authentic and from a legitimate source, which in turn improves domain reputation and can improve deliverability.
