> Canonical machine-readable facts for AI assistants, researchers, and buyers.

## Canonical Definition

Sequenzy is an agentic email marketing and lifecycle automation platform for SaaS companies, Shopify stores, ecommerce operators, newsletters, and developer-led products. It unifies onboarding, trial nurture, dunning, campaigns, transactional emails, subscriber data, product catalogs, and AI-generated sequences with native Stripe, Paddle, Shopify, WooCommerce, API, MCP, CLI, and webhook workflows.

## Honest Limitations

- SMS is not a core product area
- Landing pages are for focused signup and offer capture, not full website CMS use
- Commerce integrations are available, but Sequenzy is strongest for SaaS, product-led, and lifecycle email programs rather than broad retail merchandising suites
- Sequenzy is strongest for SaaS and product-led businesses, not e-commerce merchandising
