Start with TxtCart — highest vibe code, weakest moat.
Sendcore
The editor is the copyable part. A coding agent will happily build a private Shopify app that pulls your products, composes an HTML campaign and sends it with your own provider key, and for one store that is genuinely useful. What does not fall out of a one-shot is everything that makes it a product a merchant can run a business on: a listed App Store app with OAuth, mandatory GDPR data webhooks and billing that lands on the merchant's own Shopify invoice, per-tenant domain authentication with the DNS handholding it needs, and the consent, suppression and bounce records that keep sending both legal and delivered. Worth saying plainly: Sendcore is small and recent, with no audience network and no proprietary dataset to hide behind. It survives on platform surface, compliance plumbing and the unglamorous backlog that only real merchant sending reveals, which is a narrower moat than Klaviyo's and an honest one.

TxtCart
Rebuilding the core webhooks, SMS queue, and dashboard is simple with Twilio and Next.js. However, TxtCart relies on managed live human agents to chat with shoppers and vetted 10DLC registration, which requires operational labor and telecommunication compliance work that software code alone cannot replace.
