POP3 vs IMAP: Which Should You Choose?
POP3 downloads mail to one computer; IMAP keeps mail on the server and mirrors it to every device. The right choice depends on how you work — and on your plan's storage model.
Step-by-step
- How POP3 works: your client fetches messages and (optionally) removes them from the server. Your computer becomes the permanent archive; server space stays free.
- How IMAP works: messages live on the server; every device shows the same folders, read status and sent items. Server space fills as mail accumulates.
- Choose POP3 if: you mainly use one computer, you want an unlimited local archive, or you are on an EconomicalHost plan where mail space is working space (shared hosting, Linux mail server) — POP with remove-after-7–14-days is the recommended setup.
- Choose IMAP if: you genuinely need the same mailbox live on several devices and your plan has storage to match (e.g. Enterprise Email Hosting with 30 GB mailboxes).
- A practical hybrid: POP3 on the main office computer set to remove after 14 days, plus phone access via webmail — recent mail is visible everywhere, archive lives on the PC.
- Configure your choice using the standard settings: see ports and SSL and the setup guide for your client.
💡 Good to know
- POP3 by default only fetches the Inbox — Sent items stay local to each device.
- Switching from IMAP to POP later is easy; just add the account again as POP and let it download.
- Whichever you choose, always use the SSL ports (995/993/465).
