Simply log into your Gmail account, type the name of the person or business you are looking for in the search bar, and hit enter. This will bring up all of the emails that match the search criteria, including any email addresses that may be associated with that person or business.

On your computer, go to gmail.com. Enter your Google Account email address or phone number and password. If information is already filled in and you need to sign in to a different account, click Use another account.

You can access the Account Recovery form from the password-assistance page by selecting "I don't know my password," entering your username, and clicking the link to verify your identity on the following page.

Authentic emails sent from Google to your Google Account will never ask you to sign in again to the account they were sent to. To verify an email is really from Google, you can check that the sender is no-reply@accounts.google.com. If an email comes from another address, it's not from Google.
