How do IMAP and POP3 differ, and why do they matter?
IMAP and POP3 are protocols used for receiving emails. IMAP allows users to view and manage their emails directly on the email server, which means any changes made (like reading or deleting an email) are synchronized across all devices. POP3, on the other hand, downloads emails from the server to a single device and usually deletes them from the server afterward. For Email Marketing, understanding these protocols helps in designing campaigns that are accessible and manageable for users on different devices and platforms.
