Adding an Email Link in SharePoint site page

There was a requirement raised by one of my user to add Email lnk to the SharePoint site page, I followed below steps to achieve this

 

Add Content Editor Web Part on the page and in source editor insert following code

<a href="mailto:abc@xyz.com">Email Us</a>

or 

open a site page in SharePoint Designer, select the location where you have to put the link and then insert above code

or 

if you want users to directly open email link on a page when they click on "Email Us / Contact Us" button then assign "OnClick" event to Contact Us button / tab with above code 

<INPUT TYPE="button" VALUE="Email Us" onClick="parent.location='mailto:abc@xyz.com'">

hope this helps
