Adding a Link to Your Email Address
The mailto link is not recommended as it is not widely supported:
Mailto clickable links do not always function correctly for the site visitor. The software mechanism activated by the link requires that a default email client be established on the computer. This must be a local program, typically using the SMTP protocol to send outbound mail. With the rise in use of webmail-based email, many computers lack local email client software. Alternatively, email client software may have been preinstalled by the computer vendor, but never used or configured. When such a visitor clicks on a mailto URI in their web browser, either the browser will display an error to the effect that no default email client exists, or the user will be subjected to a volley of technical questions by the unconfigured email client. Neither is a desirable outcome. Some web browsers such as Opera, Firefox, and Chrome may be able to redirect clicks on mailto links to a chosen webmail service, but Internet Explorer as well as other browsers have no such capability.
