I will send an email with a given address by open the standard email program like \"mailto:\" in an a-tag will do it, but within a button click.
How?
Example from here
private void btnEmail_Click(object sender, EventArgs e) { string command = "mailto:info[at]codegain.com?subject=The Subject&bcc=vrrave[at]codegaim.com"; Process.Start(command); }
