Create different opt-in type that can differentiate between an opt-in for lead capture and an opt-in on an order form. This way you can have a lead capture and an order form on the same page, without any problem, like any other e-commerce website we visit everyday. The opt-in for your lead capture could be added to your lead nurture sequence while the opt-in from your order form could be added to your abandon cart sequence. Right now, if you have an opt-in on your lead capture form or order form, they enter the same automation sequence, which is a non sense.
