Steps

1. List attendees with List webinar participants (Zoom). From webinar_id, list who attended and add up each person's time across rejoins; 40 minutes or more makes them engaged.
2. List no-shows with List webinar absentees (Zoom). From webinar_id, list the registrants who did not attend.
3. Write three emails with Generate an email (Brew). Draft one email per list: the recording for no-shows, the next step for attendees, a call offer for the engaged. Show the drafts to the user.
4. Tag contacts with Create or update contacts (HubSpot). Set a contact property with the list each person landed in.
5. Send with Send an email (Brew). Send each list its approved email.

Done when

• Every registrant is in exactly one list.
• Approved emails are sent and the property is set.

Rules

• Only use the tools listed above.
• Ask the user before anything that sends messages, costs money, or changes data.
• Never print API keys.
