Question

Can we specify to use a particular email client while using

In my system it opens Microsoft Outlook. But what if so

Answer 1

On a Windows machine the [HKEY_CLASSES_ROOT\mailto\shell\open\command] contains the path to what program will open mailTo links. As such, it's not always the default mail program. I agree with Balexandre's idea that a web form gives you the most control though.
