Getting Yes/No

I was wondering how to get Yes/No if in pre-launch of my program I’m doing group webinars and nurture sequence emails. I’ve followed Brookes’s advice on making the offer as concrete as possible, focused on results, but I wonder how to offer it to them. Is it something like: “Who is interested? Reply to this mail and write “interested”/I’ll give you further info?” Or make a yes/no poll at the end of the webinar?

Those are the first ideas that popped into my mind. I’m still not clear on how to get concrete Yes-No answers when I’m doing group activities and not 1:1 anymore.

Thanks in advance
