When you register for a Lotterywest membership you can choose whether you want to receive information about jackpots, Superdraws and promotions by leaving the appropriate box ticked. If you leave this box ticked you will occasionally receive emails from Lotterywest about these events. If you clear this box you will only receive emails related to your  account activity. You can change this option at any time by clicking 'My account' when accessing your Lotterywest membership via the Lotterywest website.
