Start with Sendlane — 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.

you can rebuild

  • Build a private Shopify app that syncs your products and customers, composes an HTML campaign with a product block, and sends it to a consented segment through your own email provider key.

what you lose

  • App Store distribution: OAuth install, app review and the mandatory GDPR data webhooks
  • billing that appears on the merchant's own Shopify invoice instead of a separate card
  • domain authentication onboarding and per-tenant sender reputation
  • bounce, complaint and suppression handling
  • order-level revenue attribution and automations that fire on real store events

Sendlane

While you can easily build a visual drag-and-drop flow builder with AI tools, running bulk email delivery and SMS compliance at scale is an operational nightmare. Managing dedicated IP warming, DKIM/DMARC setups, spam complaints, and US 10DLC carrier registration requires dedicated infrastructure teams. You use Sendlane for guaranteed deliverability and carrier compliance, not just for the flow UI.
