Email Migration is a method to migrate an email or multiple email messages from one email client to another email client. The protocols mainly used in email communication are POP3, IMAP, and SMTP. Post Office Protocol (POP) is a standard email protocol. It is used to receive emails from a remote server to a local client. The IMAP (Internet Message Access Protocol) is used to access emails that are on the remote web server from a local client. These two protocols are the commonly used email protocol for retrieving emails. Whereas, the Simple Mail Transfer Protocol (SMTP) is the standard protocol used by the server to send emails across the Internet.

By using this method, we can set up two email accounts with old and new mail provider and then drag-and-drop existing emails to the new email server. You can use the below step by step instructions to transfer emails to the cPanel mail account using an Outlook email client. 1) SETUP EMAIL ACCOUNT HOSTED ON THE OLD SERVER If the email account is not set up in your email client, then you need to contact your previous email provider for setup instructions. If the email account is already set up in the old server, then you can skip this step. 2) SETUP EMAIL ACCOUNT HOSTED ON THE NEW SERVER Make sure to set up the email account on the new server.
