'POP' is an acronym that stands for 'Post Office Protocol', which is a method used for retrieving email messages from a mail server.
When you set up a POP email account, the email client (such as Microsoft Outlook or Apple Mail) on your device connects to the mail server and downloads your messages to your device. Once the messages are downloaded, they are typically removed from the server. However, some email clients can be configured to leave a copy of the messages on the server for a specified period of time.
POP mail is one of the most common methods used for retrieving email messages, and it is supported by most email services and email clients. However, there are some limitations to using POP mail, such as the fact that it only retrieves messages from the server rather than syncing them across multiple devices. Additionally, because messages are typically downloaded and then deleted from the server, it can be difficult to access your messages from another device or to recover messages that have been accidentally deleted.
POP mail is a widely-used method for retrieving email messages. Although it may not be the best choice for everyone. We would recommend IMAP mail if you use email across multiple devices.
