How to send email?

Hrllo Guys.. I am a newbie in wordpress and trying to learn it.
<form method=”GET” action=”#” accept-charset=”UTF-8″> <div class=”contact-left-box”> <input placeholder=”Name” id=”name” name=”name” type=”name” value=””> <input placeholder=”Your Email Address” id=”email” name=”email” type=”email” value=””> </div>
<div class=”contact-right-box”> <textarea type=”message” name=”message” id=”message” placeholder=”Enter a cool message…” tabindex=”10″ class=”txtblock”></textarea> </div> <button type=”submit” >Submit</button> </form>
The above code is for my contact form… I was wondering how to send email.
I want to send email when I click the submit button. How I can do it??
