The only draw back with this is that you have to down load the program the day you get the email. It will not be available the next day. I have a bad habit of planning to do it later and forgetting and then missing out because I didn't remember to do it later. Of course if you decide you don't want to keep receiving the email you can always unsubscribe but I bet you won't want to.
If you would rather receive it by a feed reader you can sign up that way.
Here's the link if you're interested:
