What to look for

Does it answer attendees in real time?
On-demand only works if a viewer's question gets a real answer when they have it. Check for genuine chat, not a simulator or a contact form.
Instant vs. scheduled playback
True on-demand starts the moment someone registers; just-in-time offers a session 'starting soon' for urgency.
Follow-up and analytics
Personalised follow-ups and drop-off data turn a passive replay into a conversion channel.
White-label
A custom domain and email sender keep the experience on-brand.
Price and contract terms
Some headline prices need annual or multi-year commitments.
