You are composing an email and begin typing a person’s name or email and perhaps at one time you had an incorrect email address and it bounced back to you. Now when composing an email you are not sure which email address is correct. To remove the bad email from Google, click Gmail in the upper-left corner of the Gmail web page and select Contacts from the drop down menu. Start typing the name or address in the search field, when you see the unwanted or bad address, select it. This step will then bring up the page where you can turn this person into a contact allowing you to add, change a name, address, or birthday. From here, pull down the More menu near the top of the window and select Delete contact. If perhaps you only want to get rid of the email address as the other contact information is correct, don’t select Delete contact. Just click inside the field of the unwanted address, press Ctrl+S to select the entire address and then press Delete.
