Email Design

Design distinctive, on-brand emails — newsletters, campaigns, welcome series, promo, post-purchase, win-back, transactional, announcements. Use when the user wants to draft, write, compose, design, redesign, critique, polish, or improve an email; or send a campaign / blast / broadcast through any ESP (Nitrosend, Klaviyo, Mailchimp, ActiveCampaign, etc.). Produces a structured design brief and translates it into the sending tool's section format. Bakes in anti-slop principles: own a colour, restrained palettes, real imagery with sourced or prompted image slots, distinctive voice, no category-re

# Email Design Skill

Distinctive, on-brand emails. Produces a structured brief, then hands it to the connected sending tool. Self-contained.

## When to use

Triggered for:

- "draft / write / compose / design / build an email" (newsletter, campaign, blast, broadcast, announcement, welcome, win-back, post-purchase, abandoned cart, promo, transactional)
- "make this email less generic / less plain / more on brand"
- "redesign / critique / polish this email"
- "send a campaign through Nitrosend / Klaviyo / etc."

Skip for:

- Strategy-only ("what frequency should I send at?")
- Deliverability-only ("why am I in spam?")
- Platform selection ("Klaviyo vs Mailchimp?")
- Copywriting in isolation, no design

## The flow (five steps)

1. **Context check** — pull brand state from the connected ESP and project files. No questions yet.
2. **Ask up to three questions** — only the highest-leverage gaps. Bundle into one message.
3. **Pick an archetype, write the brief.** Commit before composing.
4. **Resolve image slots** — fetch from brand site, brand assets, or prompt the user.
5. **Translate the brief into the sending tool's format** and run a dry-run preview before approval.

---

## Step 1 — Context check (silent)

Pull what is already known. **Do not ask the user yet.**

If Nitrosend MCP tools are available (`nitro_*`):

- Read the `nitro://account` resource for brand fields (company name, brand colour, logo, fonts, physical address, voice document if present).
