What does mailto mean in front of email?

Mailto is a HTML link which upon being clicked, will open the default email client on the user’s computer to create a new message. For example, if your default email client was Apple Mail, clicking on a Mailto link on a website would open Mail and a new message to the Mailto address.

To create a mailto link, you should use the anchor (<a>) HTML element tag and fill the href attribute as follow: <a href="mailto:...">Contact us</a>. Use our mailto link generator to generate the href link value with your own parameters.
