The process ensures consistency of electronic mail data across multiple devices or mail servers. When a change occurs on one platform, such as marking an email as read, deleting a message, or composing a new one, that change is propagated to all other connected devices or servers. For example, if a user reads an email on their smartphone, the message will also appear as read when they access their email from a desktop computer or web browser.
This data mirroring offers several benefits, including accessibility, consistency, and reduced data loss. Users gain the convenience of accessing their email from any location and on any device, with the assurance that their inbox remains current and organized. Historically, individual devices managed email separately, which often led to discrepancies and data management issues. This challenge has been significantly addressed through modern techniques.
