Wanted to add: if it's a mailing for a specific show, I always mark that on the envelope...and if it's appropriate (and not limiting), mark which role I'm hoping to be seen for as well.
e.g.
Acme Agency, Attn: Opposite of Sex Casting
123 W. 45th St.
NY, NY 10019
And on the lower left corner of the envelope, I'd write,
Re: Opposite of Sex/"Deedee"
If I had the specific agent or CD's name, obviously I'd leave of the "Attn." part off of the address line, but still keep that "Re: Show/character" part on the lower left. A little Brian O'Neil ("The Business of Acting") tip for you:)
