I'm having the same problem at http://www.madlychic.com as a recent topic, but not even registered users are getting an email. I had been using Subscribe 2 for 5 months without a problem, and I didn't change any of my settings. Three weeks ago, the emails just stoppd sending when a new post went live. I looked through the troubleshooting and saw that this problem usually is an issue with the host. I can send a manual email to everyone though, so when I called my host, they said it wouldn't be a problem with them if it works manually. Help please:-)
Thanks so very much!!!!!
