IMAP (Internet Message Access Protocol) is a protocol used to access emails stored on a remote mail server. Unlike POP3, which downloads your emails to your device, IMAP allows you to view and manage your messages directly on the server.
How does IMAP work?
When using IMAP, your email client (such as Outlook, Thunderbird, Apple Mail, or a mobile app) connects to the server and displays a copy of your messages. The actual emails remain on the server until you delete them.
Main advantages of IMAP
- Access from anywhere: You can read and send emails from any device — computer, phone, or tablet.
- Synchronization: All actions (reading, deleting, moving messages) are reflected across all your devices.
- Emails stay on the server: Even if you lose your device, your emails are safe in the cloud.
IMAP vs POP3
| IMAP | POP3 |
|---|---|
| Emails remain on the server | Emails are downloaded and often deleted from the server |
| Best for accessing mail from multiple devices | Best suited for use on a single device |
| Synchronizes folders and read/unread status | No synchronization between devices |
When should I use IMAP?
IMAP is ideal when:
- You want to access your mail from different devices
- You want your emails to stay on the server
- You have a stable internet connection
Conclusion
IMAP is a modern, reliable, and convenient way to manage your email. If you're using Actiefhost services, we recommend setting up your email client with IMAP to benefit from maximum flexibility and secure access to your messages.
