When to contact and follow through on admissions

I did coaching on the feeling of “bothering someone” when I would call them when they were interested in attending my school.
Now, I feel like I don’t want to call them too much after our first and second contact because I don’t want to be the pushy salesperson. Where is the line. Does the life coach school follow any protocol. It seems the life coach school doesn’t do any of the pushy sales. I would appreciate guidance.
