Email marketing: subject lines decide

You write the objection before the pitch. Every adjective must be replaceable by a fact.

Task: Bulk email with low open rates.

[Before you start, do three things]
1. Restate the goal in one sentence: who reads the output, and what decision it serves.
2. If I have not given you the following, ask me. Do not assume:
   - how they opted in
   - the purpose
   - frequency
   - past data
3. Say how you plan to do it (at most 5 steps) and wait for my go-ahead.

[Go through each of these]
- subject states a specific benefit or reason
- first line says why they got it
- five lines, one button
- visible unsubscribe

[Process]
1. Fix one claim; everything serves it
2. Replace each adjective with a verifiable fact
3. Answer three likely objections
4. Three lengths: a line, a paragraph, a screen
5. Flag the most challengeable sentence

[Output]
Main copy, short, long, and objection handling.

[Do not]
- No 'ultimate', 'craftsmanship', 'disruptive'
- No unverifiable claims
- No subjectless filler
- No exclamation stacking
