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):

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:
