Correct Structure for Nurture/Drip Campaign?

I need help on building a drip/nurture campaign structure for manual list upload of users who are incrementally loaded into an application. I feel there are a ton of ways to go about this but I would love some advice on what works best in my situation.

Situation:

A list of users receives a specific email on a Tuesday. After the email is sent, we wait one week to see if the users activates on the application at which point they will go down one of two tracks: nonactivated and activated.

Nonactivated track - Users who do not have an activation date field filled will need to get a set of emails sent every Tuesday, but if they activate during this campaign they will need to be removed from this flow and switch to the Activated track

Activated track - Users who have an activation date field will get a different set of emails sent every Tuesday nurturing them into further application adoption.

What is the best way to go about this? Would it be a combination of campaigns?

My thinking is to create a program for the initial email scheduled every Tuesday, then refresh the list the following Monday to determine which flow a user will go into but I am stuck on how to ensure a user properly flows to the correct track upon a data value change for the activation date.

Any and all information is helpful!

Thanks!
