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.

- Out-of-the-box CAN-SPAM, CASL, and GDPR compliant unsubscribe handlers
- Zero-maintenance integration updates when Shopify updates Admin APIs
- Direct customer support for email rendering bugs in Outlook or Gmail
