Copy-Paste This Prompt to Write Your Welcome Email in 5 Minutes

Dickie and Cole lay out a 3-part “Welcome Vortex” funnel for Substack newsletters: a pinned welcome post, a matching About page, and a well-crafted welcome email. The core argument is that growth tactics (SEO, Notes, referrals) are wasted if your publication cannot convert visitors once they arrive.

Key Takeaways

The Welcome Vortex framework treats three touchpoints as a single conversion system. The pinned post answers “is this for me?” like a Costco sample. The About page mirrors the pinned post because roughly 60% of subscribers come from inside the Substack ecosystem via one-click subscribes, often without visiting the homepage. The welcome email is the highest-leverage moment because new readers forget within 48 hours unless given a reason to stay.

Welcome email formula: tell them what to expect, deliver immediate value (link to best posts or a resource), and include one low-friction CTA (reply, poll, link click). That single action trains Gmail’s inbox placement algorithm, keeping future emails out of the Promotions tab.

Included prompt template walks through a 3-round intake process (name/audience, starting content/CTA, voice sample) to generate a 200-250 word welcome email via Claude or any LLM.

RDCO Mapping

Directly applicable to Sanity Check subscriber onboarding. The welcome-email-as-deliverability-signal insight is worth testing — a reply-based CTA in our own welcome flow could improve inbox placement. The prompt template pattern (structured intake rounds before generation) is a reusable design for any AI-assisted content creation workflow.
