POP or IMAP? Here are the differences. Post Office Protocol (POP): Your email client connects to the Spookmate email server and downloads messages to your computer. When you read your email, you are seeing these downloaded copies, not the original messages that may still exist in your Spookmate mailbox. As the emails are actually on your computer, you can archive your email. You can read emails even when not connected to the internet. If you POP email to more than one device, deleting an email requires it to be separately deleted from every device. Internet Message Access Protocol (IMAP): Your email client connects to the Spookmate email server to read messages without downloading them to your computer. When you read your email, you are seeing the original messages in your Spookmate mailbox. This is useful if you want to check email using multiple devices, including checking your email from your cell phone. Deleting a message from any device will delete the message for all. Messages are stored on your Spookmate mailbox (there are storage limits). You decide which connection type you want.
