SPF (Sender Policy Framework): SPF is an email authentication method that allows domain owners to specify which IP addresses are allowed to send emails on behalf of their domain. Implementing SPF helps in preventing spammers from sending emails on your behalf.
DKIM (DomainKeys Identified Mail): DKIM adds a digital signature to your emails, which helps the recipientâs email server verify that the email was indeed sent from your domain and that it hasnât been altered during transit.
DMARC (Domain-based Message Authentication, Reporting & Conformance): DMARC builds on SPF and DKIM by providing a way for domain owners to request feedback on email authentication and enforce policies on how to handle emails that fail authentication checks.
