Marketing Attribution with CoolTShirts Project

Here is my Martketing Attribution with CoolTShirts project. I would appreciate your feedback. Thank you in advance.

Thank you for sharing!
I´ve got pretty much same results and reccomendations, except for the last one.
I would go with reccomending the top five last_touch_at. Since the other eventough they´ve got a loot of first touch responses they did not make it to the purchase phase.
But this is my personal thinking. I respect yours.
If the question was which campaings should be redone? I would go with those you´ve mentioned.
Best regards and keep coding!
