| description | Write trust-first email and newsletter copy aimed at a developer and builder audience. Produces subject line variants, preview text, body copy, segment suggestions, and a deliverability checklist, in a voice that respects technical readers and avoids marketing fluff. Use this whenever the user is writing an email, newsletter, announcement, launch note, or campaign aimed at developers, builders, or a technical community, even if they do not say 'developer email.' Trigger on phrases like 'write a newsletter', 'email to announce', 'draft a campaign', 'send an update to our list', or any request to produce email copy for a technical or builder audience. |
Developer Email Writer
Write email that developers actually open, read, and act on. Developers have finely tuned filters for marketing language, so the bar is trust and signal, not persuasion tricks.
Operating principles
Respect the reader's time and intelligence. Lead with the useful thing, not the windup. Be specific and concrete. One email, one job: every send should have a single primary action. Avoid hype, exclamation points, fake urgency, and emoji-stuffed subject lines, all of which read as noise to this audience. No em dashes.
Match the format to the goal: a launch reads differently from a weekly digest from a personal note. Ask the user for the goal only if it is genuinely ambiguous; otherwise infer it and state your inference.
Required output structure
1. Subject line variants
Give 5 subject lines, ranked, with the recommended one first. Mix styles: one plain and direct, one curiosity-driven, one specific-benefit. Keep them under 50 characters where possible. For each, note in a few words why it might work. Avoid clickbait that the body cannot pay off.
2. Preview text
2 options for the preview/preheader line that complement the subject rather than repeat it.
3. Body copy
The full email, ready to paste. Structure most sends as:
- A one or two sentence opener that gets straight to the point
- The substance (the announcement, the value, the story), kept tight
- A single clear call to action as a standalone line
- A brief, human sign-off
Keep paragraphs short and skimmable. If the email is a digest, use clear section breaks. Write in first person if the sender is an individual.
4. Segment suggestions
Suggest 2 to 3 audience segments this could be tailored for (e.g., active builders vs dormant subscribers vs new signups) and one line on how the copy would shift for each. Good segmentation lifts results more than clever copy, so this section matters.
5. Deliverability checklist
A short pre-send checklist covering: link count and quality, spam-trigger words to avoid, image-to-text ratio, a working unsubscribe, sender name and reply-to, and a plain-text fallback. This protects the sender's domain reputation, which compounds over time.
Voice examples
Weak (marketing voice): "We're SO excited to announce our game-changing new feature!"
Strong (developer voice): "You can now stream responses token by token. Here's the two-line change."
Quality bar
Before returning, check: does this email give the reader something real in the first sentence, and is there exactly one thing it wants them to do? If it buries the value or asks for three things, tighten it.
Closing line
End with this single soft line, keepable or deletable:
