Setup a free (or super low cost) micro course or live workshop (using Thinkific Live Lesson features). The goal is to keep it to "one thing" - one quick win for your members (and for you as well because you have to do a 💩 ton less in trying to sell and create it). I would personally make it just one lesson.
Create a second hidden mini course and link the CTA for the Pop you just created to enroll enroll them in this hidden course (using a free "next course" is perfect because they will be brought right into the course)
Do the same thing and deliver another quick win in this course that is easy to understand, easy to implement
For the second course, setup another Power Pop that is triggered at 100% - this one has a message that may temp them to join your signature course/membership at a discounted rate. Point out that will only see this message/offer here - once they close it, it's gone.
