Integration email sequence

I’ve been trying to figure out my click funnels x infusionsoft email/purchase integration.
I have my email sequence integrated and connected with my funnels so that when the customer buys each upsell they get the corresponding email sequence.
I’m trying to figure out how to properly tag each sequence so the customer gets put into the correct sequence.
I have submitted the first web form to test the campaign, but I end up getting the wrong email.
I hope this makes sense! Thanks
