As of September 28 I have not received any email notifications of new followers. (I'm still getting Comment and Reblog notifications). I looked at Settings and Follows has a check mark in its box. I did not change any settings between the time I was receiving the email notifications of new followers and when the email notifications stopped.
Also, I checked my spam/junk email folders and nothing there either.
