Bootstrap is just javascript. You could use the following:
function sendMail() {
var link = "mailto:my@example.com"
+ "?cc=myCCaddress@example.com"
+ "&subject=" + escape("This is my subject")
+ "&body=" + escape(document.getElementById('myText').value)
;
window.location.href = link;
}
This will open mail client on the calling machine with set elements.
If you want to send from your server then you HAVE to have server code. You could access it via AJAX.
If this helps, please take time to accept the solution.
