Push mail ensures reliable email delivery through several key mechanisms:
Real-time Notification: Instead of relying on users to manually check for new emails, push mail actively notifies the device when a new message arrives. This reduces delays caused by polling intervals in traditional fetch-based systems.
Persistent Connection: Push mail maintains a constant connection between the email server and the client device. This allows immediate delivery as soon as an email is received on the server, minimizing latency.
Efficient Bandwidth Usage: Unlike polling methods that repeatedly check for updates, push mail only transmits data when there’s new content, saving bandwidth and improving efficiency.
Server-Side Management: The email server handles the delivery process, ensuring that emails are queued and resent if the initial push fails due to network issues.
Example: A user receives a work email on their smartphone via push mail. The email server detects the new message and instantly pushes it to the device, even if the user hasn’t opened the email app. This ensures timely access compared to older systems that required manual refreshes.
