What Are IMAP and POP3? Which Should I Use?

When setting up your dotCanada email in any email client, you'll be asked to choose between IMAP and POP3. Here's what each one means and which we recommend.

IMAP - Internet Message Access Protocol

IMAP keeps your emails stored on the server. Your email client syncs with the server, so every device - your phone, laptop, tablet, and webmail - shows the same inbox, folders, and read/unread status.

• Best for people who check email on multiple devices
• Emails are accessible from anywhere, including webmail
• Deleting or moving an email on one device reflects everywhere

POP3 - Post Office Protocol 3

POP3 downloads emails from the server to your device and usually deletes them from the server afterward. Once downloaded, the emails live only on that one device.

• Can work offline once emails are downloaded
• Not ideal if you use more than one device
• No sync across devices

Which Should You Use?

For most people, IMAP is the better choice. It keeps everything in sync, works seamlessly with webmail, and ensures you don't accidentally lose email by downloading it to a single device.

POP3 may suit you if you only check email from one computer and want to store everything locally. Otherwise, stick with IMAP. If you're not sure, contact our support team and we'll help you choose.
