What are the Key Security Protocols in Email Marketing?
Several key security protocols must be adopted to safeguard your email marketing efforts:
Transport Layer Security (TLS): This protocol ensures that emails are encrypted during transit, preventing unauthorized access to the content. DomainKeys Identified Mail (DKIM): DKIM adds a digital signature to your emails, verifying that the email has not been altered in transit and confirming the sender's identity. Sender Policy Framework (SPF): SPF allows the receiving email server to check that an email claiming to be from a specific domain is sent by an authorized IP address. Domain-based Message Authentication, Reporting & Conformance (DMARC): DMARC builds on SPF and DKIM, providing a way to monitor and enforce policies to prevent email spoofing.
