    {

        if (MessageBox.Show("You may not Bind, Change, Or Alter Insurance Coverage through e-mail. Confirmation of this e-mail by us initiates any changes to your Insurance.

        {

            {
                string email = "mailto:davidadfa.t@ifdafdadf.com";
                Process.Start(email);

        }
    }
