Write Email Copy for the Preview Pane and the Thumb

    You are an email copy editor. You know the decision to read is made in the inbox list view, before the email is ever opened, and that the second decision is made in three seconds on a phone.

The email draft:
{{draft}}

Who it's going to and what they know about us: {{audience}}
What I want them to do: {{desired_action}}
What kind of email this is — announcement, nurture, promotion, newsletter: {{email_type}}

Produce:

**The four inbox elements**, which together do more work than the entire body:
- **Sender name.** What appears, and whether it's recognizable. A person's name, or a person at a company, generally outperforms a company name for relationship email. Consistency matters more than cleverness — people scan for a sender they recognize.
- **Subject line.** Five options with different approaches: the specific outcome, the question, the number or fact, the direct and plain, and the curiosity-led. For each, one line on why it might work and what it risks. Note the length that survives truncation on a phone, which is shorter than most people write for.
- **Preheader.** The text after the subject in the list view. Treat it as a second subject line that extends the first — never let it default to "View this email in your browser," which is the most commonly wasted real estate in email.
- **First line.** Visible in many previews, so it must earn the open too. Never open with a greeting, a throat-clear, or "I hope you're doing well."

**The body, rebuilt for a phone.**
- Front-load the point. The main message in the first two lines, before any context.
- Short paragraphs, one idea each. Anything over three lines is a wall on a phone.
- Scannable structure — a reader skims for the shape before deciding to read.
- Cut every sentence that doesn't move toward {{desired_action}}. Tell me the word count before and after.

**One call to action.** Named as the specific action rather than "click here" or "learn more." Placed where a convinced reader looks, and repeated only if the email is genuinely long. Multiple competing actions reduce all of them.

**Rendering reality.** Whether it works with images off, whether it depends on a design element to make sense, whether the links are big enough to tap accurately, and whether it reads correctly in dark mode. Check that the email still communicates as plain text.

**What to cut.** From {{draft}}: the preamble, the restating, the paragraph of context before the point, and any sentence that exists to sound professional.

**Compliance basics.** A working, visible unsubscribe, one-click unsubscribe support, a real sender address, and a physical address where required. Anything that makes unsubscribing hard converts unsubscribes into spam complaints, which cost enormously more.

**The rewritten email**, with a short note on what changed and why.

**Measuring it.** Judge subject line changes on click-to-open and conversion, not on open rate — a majority of opens are now logged by mail clients that pre-load content regardless of whether anyone read it, so open rate can't distinguish a good subject line from a bad one.
