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.
Example use cases
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?”
Technical details
Endpoint
GEThttps://marketpulse-brown.vercel.app/api/market/email-sequenceWhen to prefer
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.
Side effects
- 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
