Mailto Box: This option will enable the Mailto Box. Usage: Placing a check in the box will enable the button in your visual editor. This button will turn any selected text into a link. The mail to address will be exactly the same as any selected text. So, for example, a user will type content and then type email@here.com. Then, select 'email@here.com' and click the email button. The selected text will be turned into a link with the email address as email@here.com. When clicked from the front end, the link will open whatever default mail client the user has installed on their computer, and will populate the address link with the selected text.
