# 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.
+ 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, Brevo, MailerLite, Drip, Salesforce Marketing Cloud, Symplify, Braze, or any ESP.
+ Works with zero accounts. Connected tools only sharpen it (see **Works with**).

## Usage
`/welcome-series https://brand.com` — generate a welcome series for the brand
+ ## Works with
+
+ Every step runs on the brand URL alone. With Cogny connected (`mcp__cogny__list_integrations`), these add real data:
+
+ | Job | Provider (Prefix) | Tools | Changes the output how |
+ |-----|-------------------|-------|------------------------|
+ | Signup sources | HubSpot Forms (`HubSpot_Forms`) | `list_forms` → `get_form_submissions` (`form_id`, `submitted_after`) | `page_url` per submission shows which pages and offers capture subscribers; E1 references the actual offer they signed up for |
+ | Signup sources | GA4 (`Google_Analytics_4`) | `tool_run_report` (`dimensions: ["sessionSourceMedium","landingPage"]`, `metrics: ["keyEvents"]`, last 90 days) | Which channels bring signups; tunes tone for paid vs organic vs referral cohorts |
+ | Signup sources | Plausible (`Plausible`) | `breakdown` (`dimension: "visit:source"`, `filters: [["is","event:goal",["<signup goal>"]]]`) | Same, for Plausible sites |
+ | Existing welcome flow | Klaviyo `list_flows`/`get_flow` · Mailchimp `tool_list_automations`/`tool_get_automation` · Rule `tool_list_journeys` · Drip `list_workflows`/`get_workflow` · SFMC `list_journeys`/`get_journey_email_performance` · Symplify `list_journeys` · Braze `braze_list_canvases`/`braze_get_canvas_summary` | Finds a live welcome flow to benchmark against; output becomes "keep / rewrite" per email |
+ | Existing welcome flow | Get a Newsletter, Brevo, MailerLite | not exposed by the MCP | Ask the user to paste the current series |
+
+ Name the source on every number ("HubSpot Forms: 62% of signups from /pricing"). If GA4 and Plausible are both connected, show both; don't merge them. The skill never writes to an ESP.
+
## 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.)
+ ### 1b. Enhanced when connected — signup sources and the current flow
+
+ If Cogny isn't connected, skip this and note what connecting adds (which forms and channels bring signups, and the live welcome flow to benchmark against).
+
+ 1. **HubSpot Forms:** `list_forms`, pick the newsletter/signup forms, then `get_form_submissions` with `submitted_after` = 90 days ago. Group by `page_url` and by any source/offer field in `values`. Report the top 3 capture pages and their share.
+ 2. **GA4 or Plausible:** the top 5 source/medium rows for the signup key event or goal. Note if most signups come from paid social (lower intent: lead with the offer) or organic search (higher intent: lead with education).
+ 3. **Existing welcome flow:** if the ESP exposes flows (table above), find the one triggered by list signup. Record its emails, delays and, where available, open/click rates per email (SFMC: lifetime totals; Braze: last 30 days via `length: 30`). Klaviyo, Mailchimp and Brevo opens include Apple MPP; compare clicks first.
+ 4. Feed this into Steps 3–6: match E1 to the real signup offer, set the trigger per capture source, and mark each new email as **replace** or **add** against the current flow.
+
### 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
+ - **B2B SaaS** — education, use case, ROI proof, then the conversion step that fits the model: **free trial** (time-boxed, nudge before it ends), **freemium / free tier** (no deadline; push activation and the usage limit or feature that makes upgrading worth it), or **sales-led** (demo booking)
- **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 |
+ | # | Day | Goal | DTC angle | B2B SaaS — free trial | B2B SaaS — free tier / freemium |
+ |---|-----|------|-----------|-----------------------|---------------------------------|
+ | 1 | 0 (immediate) | Welcome + set expectations | Brand story + incentive delivery | Activation: "here's your first win" | Activation: "here's your first win" + what the free plan includes |
+ | 2 | +2 | Social proof | Best-sellers + reviews | Customer case study | Case study of a user who grew from free to paid |
+ | 3 | +4 | Education / how-to | How to pick the right product | Use-case playbook | Use-case playbook inside the free limits |
+ | 4 | +6 | Objection handling | FAQ + guarantee | Pricing / ROI clarity | "What paid adds": the limit or feature they'll hit next, with pricing |
+ | 5 | +9 | Soft push | Offer reminder + last chance | Trial nudge (before it expires) + booking link | Upgrade nudge tied to usage (no fake deadline) or 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)?
+ - **Trigger** — who should receive this (new list signup, first purchase, trial start)? If signup sources were pulled in Step 1b, name the forms/pages that should enter the flow and whether any source needs its own E1.
- **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:
```
