Making offers to an email list- does that count?


Does it count as an offer if I email my list and ask them to respond with a yes or no? I usually just email my list and count the “yes’s” based on the number of people who end up purchasing. Wondering how to do the 1:1 offers given my business model of launching several times a year through email/webinars as I’m talking to a group of people at once and people either buy or don’t. It’s easy to count my yes’s based on purchases but not so easy on no’s so do I just ask them to respond no matter if they buy or not so I can hear their objections? My email list is too large to email everyone individually. Thoughts on if I’m doing this right given my stage of the business.
