What is Improper Authentication in Email Marketing?
Improper authentication in email marketing refers to the failure to properly verify the identity of the sender, which can lead to a range of issues including spam, phishing attacks, and reduced email deliverability. Authentication protocols like SPF, DKIM, and DMARC are designed to ensure that emails are sent from legitimate sources. When these protocols are not correctly implemented, it opens the door for malicious activities and can seriously damage a brand's reputation.
