our call
Start with SmartrMail — highest vibe code, weakest moat.
Seguno
Seguno is essentially a native wrapper around transactional/marketing email sending APIs tied directly to Shopify hooks. Building the core automation engine takes days with modern tools like Next.js, Resend, and React Email. The main challenge is managing ongoing email deliverability and compliance rather than software complexity.

- Shopify Polaris-embedded admin interface for managing campaigns
- Dynamic discount code generation and injection via Shopify GraphQL API

- Open and click-through performance analytics dashboard
what you lose
- Pre-tested HTML email templates optimized across legacy email clients
- Shared sender IP reputation management and deliverability monitoring
