Yeah, Zoom is solid, but have you considered Microsoft Teams? It integrates well with other Microsoft Office apps, and it's great for collaboration. Plus, you can schedule and join meetings directly from Outlook. What i think actually you can find a lot of good
webinar software and those which can really improve your overall perfomance as well as technical side of your webinars. So i guess that you can find a lot of software if you wish, and thus i believe that you can do your own research by the way, why not?
