Start with Emarsys — highest vibe code, weakest moat.
Emarsys
Rebuilding basic transactional email logic or simple visual email builders is quick, but Emarsys functions as an enterprise Customer Data Platform (CDP) and deliverability manager. It handles millions of event ingestions, multi-channel push/SMS/email orchestrations, and complex compliance frameworks. Building the application shell is easy; replacing the deliverability reputation, ISP relations, and SAP ERP integrations is not.
you can rebuild
- Triggered transactional email workflows based on order state changes
- Basic user segmentation by purchase count, recency, and spend
- HTML email template rendering with dynamic variable insertion
- Scheduled promotional email broadcasts
- Webhook ingestion for e-commerce cart and checkout events
what you lose
- Dedicated IP warming and direct ISP deliverability management
- Native SAP Commerce Cloud and SAP ERP bi-directional sync
- Built-in multi-channel orchestration (web push, mobile app push, SMS, ads)
- Turnkey TCPA, GDPR, and CASL consent audit logging and management
- Predictive machine learning models for customer churn and lifetime value
real moats
- Deep native integrations into SAP enterprise suite
- High-volume deliverability reputation and ISP relationships
- Strict multi-jurisdiction compliance and security certifications
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.
