If you are talking about DISboard emails, mine appear to be coming from webmaster@disboards.com . All you should get from here are notifications of threads you have asked for email notification on, PM notifications if you have that enabled and extremely rarely (I think have gotten 2 or 3 in all my time here) maybe a blast that goes to all members. The DIS itself does not send out email with any discount information.
You can also subscribe to the newsletter. I am not sure what email that comes from. It may have some discount information from our sponsors, but generally any offer that a sponsor is making is available in an Administrative sticky form at the top of many of the boards or is within their banner ad.
Our Authorized Disney Vacation Planners are here to provide personalized, expert advice, answer every question, and uncover the best discounts.
Let Dreams Unlimited Travel take care of all the details, so you can sit back, relax, and enjoy a stress-free vacation.
