Email authentication is a collection of techniques aimed at providing verifiable information about the origin of email messages. It helps in ensuring that the email you receive is indeed from the claimed sender and not from someone spoofing their identity. This is crucial in Email Marketing to maintain trust and credibility with your audience.
Why is Email Authentication Important?
Email authentication is essential for several reasons:
There are several widely used email authentication protocols:
SPF (Sender Policy Framework): It allows the owner of a domain to specify which mail servers they use to send email from that domain. DKIM (DomainKeys Identified Mail): It adds a digital signature to emails, which is used by the receiving server to verify that the email hasn't been altered during transit.
