# Welcome Series Writer

Generate a full 5-email welcome/onboarding series for any brand from a single URL — subject lines, preheaders, body copy, CTAs, and send timing. Output is ready to paste into Klaviyo, Mailchimp, Rule, Get a Newsletter, or any ESP.

## Usage

`/welcome-series https://brand.com` — generate a welcome series for the brand

## Steps

### 1. Research the brand
WebFetch the URL. Also fetch `/about`, `/pricing` or `/shop`, and a representative product page if they exist. Extract:
- **Value proposition** — the one sentence they'd lead with
- **Voice / tone** — playful, authoritative, technical, warm?
- **Audience** — who is this for (role, industry, stage of life)?
- **Product/category mix** — what do they sell, price points, hero items
- **USP / differentiator** — why this brand vs alternatives
- **Social proof available** — reviews, press, customer count, notable logos
- **Existing incentive** — signup offer visible on the site (10% off, free shipping, etc.)

### 2. Classify the business model
Pick one; it changes the arc:
- **Ecommerce / DTC** — hero product push, social proof, UGC, offer
- **B2B SaaS** — education, use case, ROI proof, trial nudge
- **Content / media / newsletter** — best-of archive, creator intro, community
- **Services / agency** — credibility, case studies, consultation CTA
- **Course / info product** — transformation story, curriculum preview, bonus

### 3. Plan the 5-email arc

Default cadence (tune based on business model):

| # | Day | Goal | DTC angle | B2B SaaS angle |
|---|-----|------|-----------|----------------|
| 1 | 0 (immediate) | Welcome + set expectations | Brand story + incentive delivery | Activation: "here's your first win" |
| 2 | +2 | Social proof | Best-sellers + reviews | Customer case study |
| 3 | +4 | Education / how-to | How to pick the right product | Use-case playbook |
| 4 | +6 | Objection handling | FAQ + guarantee | Pricing / ROI clarity |
| 5 | +9 | Soft push | Offer reminder + last chance | Trial nudge + booking link |

### 4. Write each email
For every email, produce:

```
Email N — [day offset]
Goal: [what this email moves the reader toward]

Subject line: [40–55 chars, written in brand voice]
Alt subject A/B: [different angle, same length]
Preheader: [85–100 chars, extends subject — never repeats it]

Body:
[Hook — 1-2 sentences, reader-facing, no "as a valued customer" nonsense]

[Middle — the actual payload. Use short paragraphs. One bolded line for scanners.]

[CTA — single primary CTA, action verb, button label]

Sign-off: [person's first name if brand has a founder voice, else brand]

P.S. [optional — the P.S. is read more than the body; put the juice here]
```

**Rules:**
- Subject ≤55 chars (mobile truncation). Preheader NEVER duplicates the subject.
- One primary CTA per email. If you must add a secondary, make it text-link only.
- No "Dear [First Name]" robotics. Use the brand's actual voice.
- Reference specifics from the site (real product names, real differentiator), never generic filler.
- If the brand has an incentive already on-site, honor it in Email 1 and reference it decaying in Email 5.

### 5. Deliver the output

Format as copy-paste-ready blocks, one per email. Include a summary table at the top:

```
Welcome Series: [Brand]
Business model: [DTC / SaaS / Content / Services / Course]
Voice: [1 line]
Hero USP: [1 line]

Arc:
E1 (Day 0) — Welcome + offer
E2 (Day 2) — Social proof
E3 (Day 4) — Education
E4 (Day 6) — Objection handling
E5 (Day 9) — Soft push
```

Then each email in full.

### 6. Segmentation + send-time recommendations
End the output with a short "Setup notes" block:
- **Trigger** — who should receive this (new list signup, first purchase, trial start)?
- **Exit conditions** — when should a subscriber skip ahead (e.g. makes a purchase → exit promo emails)?
- **Suggested send window** — based on business model (B2C: 8–10am local; B2B: Tue/Wed 10am recipient-local)
- **A/B test idea** — one specific test for the first 30 days

### 7. Upsell block
End with:

```
