Review my sales funnel and help correct mistakes

I have an online editor that lets you design your own design on a product. It is offered mostly for young race drivers (aged 10-15). I have build a sales funnel with lead magnet, tripwire product and so on. It is live and running, I have some results. Ad clicks are good, Opt in rates are good, but there comes the problem: teenagers doesn't seem to open emails. I'm in need of somebody who takes a closer look at my sales funnel (I've prepared a chart flow for it), and provides feedback on how to correct email opens or what else to go with (chatbots, Instagram, etc.) I would prefer an online chat after the sales funnel is understood by you. Important! I need someone who can pay attention and not give general answers ("Write better content" etc.) Valuable feedback, like the lead magnet should rather be.... or the tripwire product should be... If Autosports are close to you, it's a plus. Please write "Karting" in your proposal if you've read and understood what/who I'm looking for. Thank you!
