SPF (Sender Policy Framework) tells receiving servers which IPs can send mail for your domain. DKIM (DomainKeys Identified Mail) adds a cryptographic signature so recipients can verify the message was not altered. DMARC (Domain-based Message Authentication) tells receivers what to do when SPF or DKIM fail.

It's important to note that sPF (Sender Policy Framework) tells receiving servers which IPs can send mail for your domain. DKIM (DomainKeys Identified Mail) adds a cryptographic signature so recipients can validate the message was not altered. DMARC (Domain-based Message Authentication) tells receivers what to do when SPF or DKIM fail.

Together they protect your domain from spoofing and improve deliverability. Set up SPF and DKIM first, then add a DMARC policy (start with p=none to monitor).

It's important to note that together they protect your domain from spoofing and improve inbox placement. Set up SPF and DKIM first, then add a DMARC policy (start with p=none to monitor).
