If you’re using Gmail and you’re running out of storage space, it’s important to clean up your inbox by deleting large messages that are taking up too much space.
1. First, click the small down arrow in the Google search bar at the top of the screen. This will bring up the advanced Gmail search box, which allows you to search for specific types of messages.
“cc” (carbon copy) and “bcc” (blind carbon copy) are both carbon copy features in email.
You may remove those messages using the most memory and free up a lot of space in your Gmail account.
Add a custom signature, with image presumably, to every email you send.
