How to Add an Email Address to Gmail
Signing in to different email accounts to check and send emails can be time-consuming. However, if you are a Gmail user, you can use Gmail’s Mail Fetcher tool to add another email account to your Gmail account. You can then receive emails sent to that address in your Gmail account. The Mail Fetcher feature also allows you to set a custom “From” address, so you can send emails from your Gmail account displaying the other email address.
Sign in to your Gmail account by going to the Gmail homepage (see Resources), entering your credentials in the “Username” and “Password” fields and clicking the “Sign In” button.
Click on the “Settings” link at the top right corner of the page and choose the “Accounts and Imports” tab.
Select the “Add POP3 Email Account” button, located under the “Check Mail Using POP3” section. The “Add a Mail Account You Own” dialog box opens.
Type the email address you want to add into the “Email Address” field and click “Next Step.”
Enter your password in the “Password” field and check the “Leave a copy of retrieved message on the server” checkbox if you want Gmail to leave copies of your email in the other email account. Unless your email provider specifically provides you with a different POP server and port number setting, leave the "POP Server" and "Port" fields unchanged, as Gmail automatically determines the right configuration for your account.
Select the “Label incoming messages” checkbox and then choose a menu option that suits your needs, if you would like to create a separate folder or label in your Gmail account for emails downloaded from the other email address.
Click the “Add Account” button to finish adding an email address to Gmail.
