Write a Launch Countdown Campaign

Write a pre-launch countdown campaign for [PRODUCT/SERVICE].

Launch details:
- What is launching: [DESCRIPTION]
- Launch date: [DATE]
- Audience: [WHO THIS IS FOR]
- Waitlist/pre-launch sign-ups collected: [YES / NO / HOW MANY]

Campaign timeline (work backwards from launch day):
1. T-14 days: Teaser announcement (email + social)
2. T-7 days: Feature reveal / deeper story
3. T-3 days: Social proof or early access story
4. T-1 day: "Tomorrow" reminder
5. Launch day: Go live announcement
6. T+3 days: Post-launch "in case you missed it"

For each touchpoint provide: email subject line, preview text, email body (100 words), and social post copy.

Tone: build anticipation without overpromising. Each message should stand alone but build the story.
