Hey, @OfficialsLB --
First of all -- I love Calendly! And so do my clients.
I know the type of functionality you're looking for, but I don't think you're going to find anything like that directly from Zoom any time soon. Look in the Marketplace to see if maybe there's an add-on for that.
For some of my clients, I've successfully used Eventbrite as the registration platform, and there is a significant email capability built in there -- though I don't think you can request/require answers from them to confirm attendance... but they might be more willing to add that functionality or help you with finding a clever way to do that. There is a good Eventbrite-to-Zoom Webinar data feed for your registrants/participants which is relatively easy to turn on, and takes care of the cross-platform registration interface. If you'd like to chat about Eventbrite, look for the Inquire link on my web site and use the Calendly scheduler -- it's too involved to go over here.
