POP3 vs. IMAP: What's The Difference

Even though both protocols are Message Accessing Agents, POP and IMAP operate differently in email access, making one more advantageous than the other in specific situations.

Originally known as the Post Office Protocol, POP was the first widely used email protocol on the internet in its beginnings.

When you use the POP3 protocol to access your emails, a copy of the emails gets created and saved locally on your computer. The originals normally get removed from the mail server; however, this is not always the case.

Many times, emails are associated with a single device. Another email client or device can no longer view the email once downloaded onto one device and withdrawn from the mail server.

IMAP stands for Internet Message Access Protocol. Unlike POP, IMAP allows you to access the same mailbox from numerous devices because your messages remain on the server.

The IMAP protocol connects your client application to your mail server, allowing you to control your emails on the mail server itself directly. In this configuration, your mail server, rather than your local computer, serves as the primary storage location for your emails.
