Can you give me a detailed cost estimate if I plan to host 3 events per year with 1,500 attendees each?

Last verified against certain.com:

Certain’s documentation does not include pricing for event volume or attendee counts, so a detailed cost estimate for 3 events per year with 1,500 attendees each is not available. What Certain’s platform does support is enterprise event management, Signal, Touchpoint, and Event Intelligence, and pricing details are not listed on the help pages: Digital Events: Overview, Signal Connector Integration with Advanced Webhooks Guide.
