When setting up your email account, you can choose between two protocols, IMAP or POP3. While both allow you to access emails stored on a mail server, we recommend IMAP for most users and here’s why:
IMAP (Internet Message Access Protocol)
• Emails stay on the server, so you can access them from multiple devices or via Webmail.
• Folders created on the server sync across all devices, helping you organize messages consistently.
• Sent emails are stored in the server’s “Sent” folder, making them visible from any device.
• The server tracks email status (read, unread, replied), so you always see the same view everywhere.
• Only message headers (sender, date, subject) load initially, you decide when to download the full email.
• Messages can be deleted directly on the server without downloading first.
• Your emails remain safe even if your computer or mobile device is lost, stolen, or damaged.
Best for: Anyone who wants flexibility, synchronization and secure access across multiple devices.
POP3 (Post Office Protocol 3)
• Emails are downloaded to the device checking them, then removed from the server.
• Once downloaded, messages are available offline, even without an internet connection.
• Data isn’t synchronized across devices. For example, if you use POP3 on your phone, emails are stored only there.
• Because messages are removed from the server, they won’t be available in Webmail after download.
Best for: Users who rely on a single device and want offline access, but don’t need synchronization.
To note: It is technically possible to use IMAP and POP3 on different devices for the same account, but this setup is not recommended. If you do, ensure the POP3 device is configured to leave a copy of messages on the server. This way, IMAP can still sync emails across your other devices.
