Filtering algorithms work by scanning incoming emails and applying a set of rules and criteria to identify spam, promotional content, and legitimate messages. They consider elements such as:
Sender Reputation: The historical behavior and reputation of the sender play a significant role. Content Analysis: Keywords, phrases, and links within the email are analyzed to detect spammy or promotional content. User Engagement: Past interactions of the recipient with the sender’s emails, including open rates and click-through rates. Header Information: Examination of email headers for any suspicious patterns.
