Example prompt: Can you create a 5-step nurture email sequence for my B2B SaaS product CloudSync — targeting small business owners who signed up for a free trial but haven't upgraded, including subject lines, preview text, and the best send timing for each email?

## When to prefer this

Choose this endpoint when you need ready-to-use, structured email sequences with subject lines, preview text, and timing guidance for marketing or lifecycle campaigns — especially when you want deliverability best practices bundled with the copy, rather than just raw email text generation.

## Known failure modes

- Missing required campaign or audience parameters returns an error response
- Overly vague inputs may result in generic, less targeted sequences
- API timeout if the generation takes too long
- Payment failure via x402 protocol blocks the response
- Rate limiting if too many calls are made in a short period

## How this service works

What should email #2 say — and when should it send? A complete, ready-to-use email sequence with real subject lines, preview text, send timing and body outlines for welcome, nurture, abandoned-cart, post-purchase or re-engagement flows, plus deliverability rules and the metrics to watch, for a given product and goal. For lifecycle and marketing agents.

## Output

A structured nurture email sequence with ready-to-use subject lines, preview text, recommended send timing for each email in the series, and deliverability best practices to maximize inbox placement and open rates.
