Hypothetical project (Sample marketing project)

In order to conduct your discovery effectively, you need to articulate 3-5 research questions. Basically, what do you need to learn in order to successfully complete your project?
Here’s an example. Let’s say the hypothetical project calls for me to assess a nonprofit’s email marketing process and to make suggestions for improvement. What research questions should I be asking? One question one should definitely need to ask: What is the nonprofit’s current email marketing process (email marketing vendor used, the purpose of campaigns, frequency, mailing list quality, etc.). This is information the nonprofit would have to provide you.
What other research questions should you be asking for this hypothetical project? If you were leading this email marketing project, what 3-5 questions do you think you should be asking and why?
