Adding the "Email me" link to your blog/webpage is very helpful for the visitors who want to contact you.It increases the interactivity between the visitors and your site and make them come regularly.

Hi henry! I will write the email address directly like abc@gmail.com and ask visitors to contact me.So,why to add these clickable links like"Email me" ?
There are plenty of problems if you show your email address directly on your site as SPAMMERS find your email address easily via search engines,and other sources.
So,by adding this type of links will hide your email address and If your visitors want to contact you,they will click on it.If the visior want to sent to you via another source like yahoo,google,etc they will simply copy the email address(in the outlook express) and email you.
On clicking the links,WINDOWS OUTLOOK EXPRESS will be open by default.
So,how to add the "Email me" link?
There are two types of ways to do it.One is text link and another one is image link.

Text Link:
Suppose,your email id is abc@gmail.com ,here is the code you have to add

<a href="mailto:abc@gmail.com">Email me </a>


Don't forget to change the email address in the above code to your's.If you want another anchor text(not "Email me"),you can change it.
Image link:
Suppose,if you want the visitors to email you by clicking on an image like the below one
