Gmail has a laundry list of settings that allow you to customize your Gmail experience. One of the most useful settings you can use is the email signature. An email "signature" is the block of text that is automatically pasted into the bottom of every email you send. To start, navigate to the "gear" icon in the upper right hand corner and select “settings”. The "general" tab is where you’ll find basic options for managing your Gmail account. Scroll down to the “Signature” section and begin typing your signature in the text box. Feel free to use any of the modifiers in the toolbar as your signature will retain the font style and spacing in every email. Most email signatures contain the person’s name, email address and phone number. If the email is being used for business you will often see their company name, address and title as well. Be sure to select “Save Changes” to have your settings saved.
