Hi! I am using Subscribe 8.6. Until last night, when I had 5 subscribers, everything was working smoothly. Today I started promoting the website, big moment, I got 25 new subscribers, but automatic notifications for new posts are not being sent. I am still getting emails for new subscribers, I can still send previews to my email account, etc. The email account on admin corresponds to the domain as well. I spent a couple of hours with my hosting company over the phone, in case they had restrictions (against spam, email abuse, etc) but nothing. Any idea before I tried to just install everything again? That will be dramatic, since I spent a good amount of time customizing everything into Spanish. Thanks for any help, mattyrob! (I can send you the Spanish version of your files if you want to use them, no problem with that!).
