The main difference between IMAP and POP3 is how and where your emails are stored. While IMAP allows you to access emails from any client on any device, you will not be able to access any previously downloaded emails from any other device or email client, or even through webmail, with POP3, meaning that you can only use that specific client within one device to view your emails.
Furthermore, IMAP will sync your emails so that you will always see the same messages. For example, if you delete an email in one client and then check your inbox on a different client and/or device, it will still be deleted. With POP, email will not be synced across your clients or devices.
Should I use IMAP or POP3?
When it comes to POP vs IMAP, we recommend that you always use IMAP where possible as it offers a faster, safer and more convenient way of receiving emails.
