While creating a web-application's Contact us page, you might need to include a anchor link which opens basic email program of user, with already filled in company's email id in "to" address, so here are the ways to add anchor tag using mailto in html, with and without subject.

Creating basic mailto html anchor link

<a href="mailto:someone@companyname.com">Email Us</a>

On clicking above link , when placed inside HTML code, default email program of user will open with email id provided above after mailto: keyword.
