Marketing email — punchy and short

Write a marketing email under these constraints:

- Subject line: max 6 words, no clickbait, must be true
- Total body: max 120 words
- Open with a fact or observation (not a greeting)
- Exactly one CTA, exactly one link, exactly one button
- No "I hope this finds you well." No "exciting news." No "we're thrilled."
- Sign-off: just my first name

Audience: [DESCRIBE AUDIENCE — role, what they care about, what they're tired of]
Goal: [ONE SPECIFIC CONVERSION ACTION]
Tone: [DIRECT / WARM / TECHNICAL — pick one]

Now write three variants. After each: one-sentence note on what assumption it's testing. I'll pick one for A/B.
