Good reasons to stick with POP3 email over IMAP:

The debate continues about whether to use IMAP or POP3 for email. IMAP and POP3 are the protocols you use to access email via mail clients (apps such as Outlook).
Some believe that IMAP is the way to go and the POP3 standard should be abandoned completely.
We don't entirely agree. There are valid reasons to continue using POP3, or perhaps even actively switch to it.

IMAP and POP3 basics

The key thing to know about the Internet Message Access Protocol (IMAP) is that it lets you view your email folders the same way on any device, as it’s all synchronized from a central server. With IMAP your inbox, sent, and customized folders look alike, and have the same content, whether you’re checking mail on your phone, tablet, or PC.

The Post Office Protocol version 3 (POP3), on the other hand, is specifically designed for downloading email from your email provider’s server to your local machine. Your actions aren’t synchronized with the server like they are with IMAP; it’s just a “dumb” download. Most (but not all) POP setups wipe email from their servers by default once you download it to your local device, however you can often configure your email client to leave your messages on the server for a certain time as well. We recommend 7-14 days depending on your needs.

It's all about storage

Internet Service Providers or website hosting services set limits on how much mail can be stored on their servers. It’s best to turn to POP3, so you can download your mail and wipe it off the server to stay under the storage quota.

However ...

If storage quotas are a concern, consider using a service such as Gmail or Office 365 which offers more storage space.
