In the context of email marketing, the primary DNS records to monitor are SPF, DKIM, and DMARC.
- SPF (Sender Policy Framework): It specifies the mail servers authorized to send emails on behalf of your domain. - DKIM (DomainKeys Identified Mail): It adds a digital signature to your emails, verifying that they havenât been altered during transit. - DMARC (Domain-based Message Authentication, Reporting & Conformance): It tells receiving servers what to do if an email fails SPF or DKIM checks.
