Why are Rules disengaging all of my audience?

Do I not understand Series? Something isn't adding up.

I am attempting to add Rules to a Series to accomplish the following:

• I send one email
• If someone doesn't open it, they go on one path and get a couple more
• If someone opens it but doesn't click the link, they go on another and get a couple more

I set Rules to cover these parameters, but it automatically disengages my entire audience.

So...now what? I'm just stuck making a new Series? People are just...disengaged and that's it? Can I restart it?

This has been very frustrating.

Second question...how the heck do I troubleshoot and test these things?!

thanks
