It depends. They started sending beta invite emails for this beta on Sunday I believe. If you entered a code between then and yesterday when the beta started, most emails would come within a few hours of applying the beta code (from the few people I talked to). However, I don't know if that process is slowed now that the beta is actually happening or not. I would say give it 24 hours, then send them an email.
edit: well then, nevermind :P.
