What is the difference between POP3 and IMAP?

When setting up your StackMail email, you might be wondering: Should I use IMAP or POP? Well, both protocols are used to receive incoming emails, however, there are significant differences:

If you opt for IMAP, any modifications you make to your emails (reading them, deleting messages etc.) will be synchronized across all the devices you use to access your email as the messages will still be stored on the StackMail mail server. On the other hand, with POP, changes will only be reflected on the device where you initially downloaded the message to.

➡️ A general advice is to choose IMAP instead of POP, as it allows you to access the same emails on multiple devices like smartphones, tablets, and PCs. However, if you have a large mailbox and need to conserve storage capacity, POP3 becomes a considerable option. With POP, emails are downloaded to your device, freeing up storage capacity in your mailbox.
