Overview
Zoho Mail offers multiple ways to access your email accounts from different service providers within the Zoho mailbox. Email protocols like IMAP and POP are application layer protocols, providing the ability to fetch emails from one server to another. They work by establishing a TCP link. Understanding and knowing the difference between IMAP and POP will help you in choosing the right protocol to facilitate your requirements.
POP3 vs IMAP
IMAP and POP cater to the needs of people with different requirements. If you are someone who only accesses email at a single device and doesn't have continued active internet access, POP may be the protocol to go with. But if you use multiple mailboxes and can't worry about keeping track of emails at a single device, IMAP may be the one.
