How to effectively automate a one-to-many webinar process

Bjame010

Hello All, 

My team is launching a fully digital onboarding and engagement process for our small market clients, and we are going to be leveraging Zoom Webinars, coupled with Salesforce and ChurnZero to drive adoption with our small market clients. Where I'm struggling is with the mechanics of how to track who signs up, who attends/doesn't attend, and effectively communicate follow up. 

Has anyone launched something using a similar tech stack successfully that can point me in the right direction? Best answer we have now is manually uploading lists from Zoom to CZ, and I'd like to avoid that much manual effort. 

Thanks!
