Email Client Setup: Comparing POP vs. IMAP
What are POP and IMAP?
POP (Post Office Protocol). This is a method that your email client can use to connect to our email server for retrieving messages. This connection type allows you to download messages from our email server onto your computer. When looking at your email via your email client, you're looking at your downloaded copies of those messages, not your original messages that still exist in your mailbox.
IMAP (Internet Message Access Protocol). This is a method that your email client can use to connect to our email server for retrieving messages. This connection type allows you to read messages from our email server without downloading the messages onto your computer. When looking at your email in your email client, you're looking at the original messages that exist inside of your mailbox.
When do I choose POP? When do I choose IMAP?
While it's possible to connect using either method from any email client or mobile device, we have a few recommendations for you to consider. Ultimately you get to decide which connection type you want to use.
