First, I would try and figure out why your affiliates have blocked your emails. There could be a couple of reasons.
Maybe they don't want to be receiving emails from SFI.
Possibly, they don't like the amount of emails they are receiving from you or maybe the tone.
So, definitely dig into the reasons Why?
Secondly, you still have the team mail that can be used. Maybe, use the team mail to ask the question.
If you don't receive any kind of feedback, the being an awesome sponsor is not going to happen. You will need to concentrate on updating your leadership page and providing guidance in that way.
