Tick Boxes

I am new to CC and would like to ask, when filling in comp entry forms, am I more likely to win any of the prizes if I tick all the boxes i.e. to sign up for newsletters etc etc. I would obviously receive more emails and phone calls but could unsubscribe?????????????????????

It shouldn’t make any difference to your chance of winning a prize draw if you decide not to join a mailing list, etc.
Good luck.
