Spent the last few years mentoring authors through launch week, and the pattern is always the same: the book is good, the writing is solid, but the launch dies by day 3 because of one structural mistake — no funnel, just a single Amazon link blasted everywhere.

A real book launch funnel looks like this:

1. Pre-launch landing page — captures emails from your audience before the book is live. If you launch cold with zero list, you're relying entirely on algorithm luck.

2. Subject line testing, not guessing — most authors write one email and pray. Test 3-4 subject line variants on a small slice of your list first (even 10% of it), then send the winner to the rest. Open rate differences of 15-20% are common, and open rate is the ceiling on everything else.

3. A tweet pack, not one tweet — one launch tweet gets buried in an hour. A pack of 10-15 posts spread across launch week — behind-the-scenes, reader reactions, countdown posts, excerpt drops — keeps you in front of your audience without looking desperate.

4. A retention layer — the funnel doesn't end at the sale. The authors who build second and third books successfully are the ones who kept a community warm after launch day instead of going quiet for a year.

Most of the '72-hour flop' problem isn't a marketing budget problem. It's a sequencing problem. Fix the order, and the same audience converts at 2-3x.
