Letter to various public officials

I have prepared an email that I want to send to a bunch of public officials that are in various government offices. I need the email to look and feel as professional as possible in a format that I can copy and paste in an outgoing email. I need the email to sound professional in hopes of generating a positive response from the recipient.. Thank you and I look forward to seeing what you can come up with. I would also like to include my signature if possible.
