Wrong Email

Although I know I will never win one of the hearst sweeps I do like to dream. The problem is, that after I enter a few time, the entry (aka) 250,000 sweeps, comes up as already filled out. This is nice BUT, everytime the entry comes up the email address for me is wrong. Usually a very subtle drop of one letter or number. and it changes from time to time. I always correct it but am curious . If the email is never correct and I have to reenter it each time, will that not affect any notification I get for a win? Something strange is going on here and I wonder if they do that so that many who do not notice the change will actually not be entering and also that even if we do win the computers at Hearst will spit out an incorrect email adress for notification? This kind of seems like a way to not award a prize.
