What are SPF, DKIM, and DMARC in email marketing?

SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting & Conformance) are email authentication protocols. They are used to improve email deliverability and protect against email spoofing. SPF verifies that an email comes from an authorized server, DKIM adds a digital signature, and DMARC ensures that both SPF and DKIM align.
