Start with Seguno — highest vibe code, weakest moat.
Attentive
Building an event-driven SMS workflow app using Node.js, standard cloud databases, and Twilio APIs is straightforward with modern AI code generation. However, replacing Attentive long-term requires navigating 10DLC registration, carrier spam filtering, TCPA legal liability, and deliverability infrastructure that self-hosted code cannot solve alone.

- Basic subscriber list segmentation based on Shopify purchase history and cart events.

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.
