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:
