IMAP, POP3 and SMTP are email protocols that handle receiving, syncing and sending messages in different ways.
Key Points
- IMAP keeps mail in sync across multiple devices and is usually the best choice for modern business use.
- POP3 typically downloads mail to one device and can remove it from the server depending on settings.
- SMTP is the sending protocol that handles outgoing email delivery.
- Using the wrong protocol settings can lead to missing mail, duplicate downloads or failed sending.
- For teams that work across phones, laptops and webmail, IMAP is usually the safest default.
