Subscribe2 not sending out email with Auto Blog

We’re using the Auto Blog plug in to publish posts to a number of blog sites. We would like Subscribe2 to notify subscribers with each such post, however no email is going out. If we post directly/manually into the blog, then Subscribe2 sends out the email, but not when content is posted via Auto Blog. Is Auto Blog failing to use a specific hook and posting directly into the database or something? Is there a way to fix this? Thank you.
