There are two possibilities why OP has receieved the above e-mail from AA:
1, He is travelling on separate tickets and the AA ticket terminates at LHR
2, AA was lazy and sent the message to all AA EXP/OWE who travels to LHR w/ them
Either way, as temppa has already pointed out, OP is transferring at T3 and thus wouldn't use the arrivals lounge anyway...
