Neither, you should you mail it. If you must send it via email, save it as an Adobe document (easy enough to do, just download a patch) and attach it to an email. Use the actual email as an introduction to the attached document.

E-mail is not formal… A typed document is formal. Yikes, we actually use typed documents as formal documents, even in 2009! So it does not have to be “typed” per se – actually printed on paper is perhaps the term I should have used. And actually put into an envelope and ’snail mailed’ to them.

That is the formal way of doing it. And just so you know it has been received, actually go to the Post Office and have it sent certified/return receipt requested. It will cost you maybe $1.50 to do that…maybe a bit more, but not much. You will have evidence it was sent and received. I know…we sort of do with e-mail, but that is simply not FORMAL.

You can send it e-mail, but do the actual written thing, too.
