Promote a webinar or event across channels

Background:
Organizer (as attendees know us): {{organizer}}
Who the event is for: {{audience}}
Social channels to cover: {{channels}}

Event details (name, date, start and end time with time zone, online link or address, price, speakers and their titles, agenda, registration link, any capacity limit):
"""
{{event_details}}
"""

What attendees get afterward (recording, slides, an offer), or "nothing":
"""
{{after_event}}
"""

Task: Write the full promotion pack for this event, so I can schedule everything at once.

Pieces, in sending order:
1. A schedule table first, with the columns Piece, Channel, When to send (relative to the event, for example "3 weeks before").
2. Invitation email, under 200 words, with three subject lines: what it is, who it is for, three things attendees will leave with (from the agenda), date and time with time zone, and the registration link.
3. Social posts for each channel listed: an announcement, one post per speaker using only the bio facts given, and a final reminder.
4. Reminder emails to people who registered, under 80 words each: one the day before and, for an online event, one an hour before the start, with the join link at the top.
5. Two follow-up emails, under 150 words each, to send within a day: one to attendees and one to people who registered but did not attend, each with what they get afterward.

Rules:
- Always give the time with its time zone, and the weekday with the date.
- Use only the details given. Do not invent speaker credentials, attendee numbers or "spots are filling fast" unless the details state a capacity and how many places are left.
- The email to people who did not attend should be friendly and never guilt-tripping.

The pack should read as one consistent voice, with the same event name, date and link everywhere.

Example of a subject line, for form only: "[Event name]: [weekday], [date] at [time] [time zone]"

If the weekday and date do not match, or any detail is missing, such as the time zone, write [needs: what] in place, list these at the top, and do not guess.
