My requirement is to open default mailer whenever i click on a link. I don't know how to do that can any one give ideas about that.
Use mailto in href attribute for opening a default mail client to send an email.
subject & target attributes are optional here.
Usage example -
<a href="mailto:test@gmail.com?Subject=Hello%20again" target="_top">
Send Mail</a>
