Gmail - Check emails from other accounts
If you have multiple email accounts, you can check them in Gmail. Learn how to add another email account to the Gmail. app.
Important: If your other email account doesn’t support secure connections, you won’t be able to connect. If you use 2-factor authorization, you might have to add a security exception for the email you are adding to your Gmail account.
