POP3 Email vs IMAP Email

IMAP and POP3 are protocols for accessing emails stored on a mail server. You can configure your email software to access email account using either IMAP or POP3.

POP3 (Post Office Protocol version 3): Mailboxes are used to send/receive e-mail for your hosted domain. All mailboxes can be created or modified through an online administration system either from within your hosting account cPanel or by accessing your mail accounts directly. POP3 Is the friendliest and most secure email account type available for private domain use. It supports a long list of email applications including Outlook, Thunderbird, MAC Mail, Netscape Mail, etc.

  • All your emails are downloaded to the computer or device checking the email. After the emails have been downloaded, they are removed from the mail server.
  • Once the emails have been downloaded to the computer or device, you can also access your emails even if the device has no internet connection.
  • Data such as emails and folders are not synchronized between different devices. This means that if you set up your email on your mobile device with POP3, the emails will be downloaded completely to your mobile device. POP3 removes the emails from the mail server. It will no longer be possible for you to read your emails in WebMail because they are already downloaded to your mobile device.

IMAP (Internet Message Access Protocol)

  • Emails remain on the email server, allowing you to set up the account on multiple computers and devices to access your email, as well accessing them through WebMail. This also means your hosting pace allocation is used toward storage. For many of our customers space consumed by email storage will exceed the size of the website itself in 9-12 months.
  • Folders can be created on the server to better manage the messages. The folders then sync across all devices used to check your email.
  • Sent messages are also saved in the sent folder, allowing you to view sent emails from any computer or device.
  • The server saves the status of an email (e.g. read, unread, replied, etc.). This allows you to see the status from any computer or device.
  • Initially, only the header (sender, date, subject) of an email is loaded. You can then decide whether you want to download the complete email message.
  • Messages are deleted directly on the server without being downloaded first.
  • You won't lose your emails if your mobile device or PC is destroyed or stolen.

Please note: It is possible, but not recommended, to use set up the same email account using IMAP and POP3 on different devices. If you choose to do this, it's highly recommended to Leave a copy of all messages on the server for the device using POP3. This allows you to still access and manage emails using IMAP on other devices.
