How this service works
Copy that converts. Landing pages, launch threads and emails, written to ship.
Output
Returns a JSON object containing a job ID, the full generated email sequence copy as a string, and a payment receipt with the transaction hash, amount in USDC base units, and the network used.
Example use cases
SaaS product launch drip campaign
“Generate a launch email sequence for my SaaS tool called InvoiceNinja — it's aimed at independent contractors who struggle with getting paid on time, written in a conversational, no-BS tone that builds urgency toward a 7-day free trial CTA.”
Online course nurture sequence
“Write me a 6-email nurture sequence for my photography course called 'Frame It Right' — the audience is hobbyist photographers wanting to go pro, and the tone should be warm, encouraging, and build toward a limited-time enrollment offer.”
Re-engagement campaign for churned users
“Create a win-back email sequence for my meal-planning app — targeting users who signed up but stopped logging meals after 2 weeks, tone should be empathetic and low-pressure, with a discount offer in the final email.”
Technical details
Endpoint
POSThttps://superscribe.supercapital.fun/email-sequence?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a ready-to-ship multi-email sequence crafted for conversion — especially for product launches, onboarding flows, or sales funnels — and want copy that reflects a specific audience and tone without manual editing. It is ideal for agents automating marketing workflows that require email copy at the sequence level rather than individual one-off messages.
Side effects
- Empty or missing 'input' field returns a validation error
- Input exceeding 8000 characters is rejected
- Insufficient USDC balance causes payment failure before generation
- Vague or extremely short prompts may produce generic, low-quality copy
- Network congestion on Base may delay payment confirmation
- Service timeout if the generation model is under heavy load
