Webinars - what systems do you use?

Hello!

As our company continues to grow, stitching up the attendee list externally with the handy VLOOKUP and manually importing the CSV to a Journey Orchestrator to send follow up emails is becoming unscalable.

Please can I ask what Webinar platforms you use that sync with GS?

In an ideal world we would like to send the invites via GS and have the data write back into GS of those that have signed up, attended/not attended, so that we can send follow up comms. 

Thanks in advance :-)
