Is there a way to edit\modify Zoom emails that are being sent out?  A way to change or add to the content & information in the email?  Modify branding?
Even as a license holder, I didn’t see an area were I could go and create my own emails or to modify existing ones.
As we will have hybrid events we’d like to send one group (in-person) a different email than the virtual attending group.

Let's face it -- hybrid events are here to stay 😷 🖥and I am on a fast learning curve to seamlessly blend virtual and in-person event experiences, from registration, ticketing and attendee emails, to day-of-show and post-show. Currently, I am exploring hybrid event registration and so far am not impressed -- this really needs to be an easy, seamless process for attendees (whether in-person or virtual) and easy to set up/manage for event planners. I am aware of event registration platforms that can integrate with Zoom (such as Eventbrite), but this seems clunky/complicated and has too much potential for error/confusion. Ultimately, I would prefer to be able to set up/manage hybrid event registration for both in-person and virtual attendees solely on the Zoom platform. Additionally, my organization has an enterprise-level license with Zoom and it would be ideal to have an all-inclusive Zoom solution for the endless stream of hybrid event requests that I am fielding from across my organization of more than 25k employees. I welcome any comments, insights, experiences on this topic and also invite Zoom (or anyone with info on this) to comment on whether an all inclusive, on-platform solution for this is in the works. 🙏 

I understand that I am not able to convert a live webinar to a meeting. Are there any workarounds so I can communicate with the attendees? I have 450 people registered for the webinar but would like the possibility to communicate with some of the attendees that live once the webinar is finished if they would like to ask live questions.

We didn’t want the original recordings to be posted immediately as we wanted to edit them before they were posted after the event. (add a starter tile, ending tile, remove a section if needed) I’ve edited the videos and I’ve gone in and “replaced” each video.

But we are unsure as to where the videos are appearing for the attendees. At the moment, they’re not showing when you went back into the lobby.  If we inadvertently turned off some function to allow them to see all videos after the event is over, how do we turn it back on again?

To add to this, a sub-question is, do the attendees only see the videos of the sessions they attended, or is it “all or nothing” when viewing the recordings?

By placeholders, I'm referring to timeslots that nothing is going on.  ie "Lunch" or "Coffee Break".  

An ability to put those things into the itinerary so the attendees understand what is happening that time, but no webinar/meeting/video is going to be played at this time.

We have attendees registered to attend a webinar and we may have to reschedule the date/time. However, if we do that, we found that it will send an email to attendees letting them know it changed, but not update their calendar. We have found this the case for google calendars.

AND -- if they add the rescheduled event to their calendar, they end up with both events and its confusing to know which is the real one. Please advise if there is a fix for this!
