POP vs. IMAP: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
POP is for downloading emails to a single device and deleting from the server; IMAP syncs messages across multiple devices, keeping them on the server.
Key Differences
POP (Post Office Protocol) is a simple, older email protocol that downloads and stores email on a single device, typically deleting them from the server afterwards. It is most useful when email access is needed from only one location. IMAP (Internet Message Access Protocol), on the other hand, is more flexible and complex, allowing emails to be accessed and synchronized across multiple devices.

POP operates on the premise that there will be one place to read your emails, like a personal computer. It is not designed for the modern age of multiple devices. IMAP allows users to read their emails as if they were all connected; actions taken on one device are reflected on all others.

With POP, the email client connects to the email server briefly to download messages. Once downloaded, these emails are typically removed from the server. IMAP maintains a constant connection with the server, where messages are stored and managed.

The simplicity of POP can be its advantage and its downfall. It makes for less use of server storage and can be quicker due to local storage of emails. Conversely, IMAP offers a more comprehensive experience, keeping the inbox experience consistent across all devices, which is more suited to how many use email today.

POP might be the right choice if you're concerned with storing sensitive emails on a remote server. IMAP is the clear winner for users who need to access their email on the go from various devices and locations.
