Validation email before confirmation order

Hello everyone,

I want to set up a validation link before confirming an order.To explain everything to you, I go through service providers to sell my products. They collect the customers and I take a commission at the end of the month.My partners collect the data and my company processes it. Therefore, I need the customer's consent before I can process the order: hence the validation email.The idea is to put in this email "yes I accept" in order to send the customer an order confirmation.Do you think this is possible?If so, how can I create a validation email and then an automatic confirmation email?thank you,cordially
