Summary
This article describes the differences between using POP3 or IMAP to connect to your email account.
POP3
POP (Post Office Protocol) is the most stable and fastest method of accessing your emails. When using POP your email is downloaded from the server to your local machine, removing the copy from our mail servers. POP is great when you are only using one computer to access your emails
IMAP
IMAP (Internet Message Access Protocol) is the best way to access your emails from a multiple devices such as PCs, Macs, laptops, iPhones and smartphones as well as tablets. Instead of downloading, your E-mails are stored on our mail servers so your E-mail travels with you and is always available since it’s not stored locally on any particular PC.
IMAP allows you to view just the subject of your e-mail messages and decide whether you want to download them. So there is no need to download an entire email, saving you time and bandwidth.
With IMAP we recommend that you regularly delete old emails from your inbox and folders
