Some thoughts- Instead of teachers and school plans, have you thought about having a parent/student plan? Every time to sign up to receive messages, you get X free and then you have to pay to receive the rest. This way you are pushing the burden to purchase on the parents's shoulders and this will also ensure that there is a parent 'by-in' for ClassParrot. Did you survey parents and students about this?
Also, if 1 credit = 1 message, then why not just call it a 'message' to keep things simple. So you get 500 free 'messages' and you pay for 500+ 'messages'.
To emphasize your value prop and highlight the safety, landing page message could again say 'secure' instead of 'hassle free'. My rule is that repetition is good.
