Hi Stuart,
I've downloaded and installed the October 16th version. Unfortunately, I have no success. When I change the content, an e-mail is not sent out to my "Test Role" with a "Test User" assigned to it.
I did notice that the common theme is if the Role exists in the aspnet_roles table then it works fine. Then I noticed that when adding a new role via the Admin Menu, it gets added to the Roles table and not the aspnet_roles table. In earlier versions, it used to. I understand that that is no longer the case and that information is now kept in the DNN Tables as indicated by the following link:

I realize that I'm using 3.3.5 and not 4.x but the activity in the link is happening to me.
Is it possible that there is an issue when the e-mail list is constructed for users that have roles in the Roles table. Is it maybe still going to the aspnet_roles table (or some similar logic). Just a hunch, I'm not sure.
I can still confirm that members of the Administrators role receives the e-mail as soon as I change the text in the module's content and clicking on update. No problems there.
Thank you for the quick response and awaiting your opinion and fixes.
