our call
Start with CartKit — highest vibe code, weakest moat.
CartKit
CartKit is essentially a queueing system listening to storefront checkout webhooks and dispatching emails or SMS via third-party providers. You pay for bundled UI, pre-built copy templates, and handled delivery infrastructure. Building a custom worker with Redis/BullMQ and Twilio/Resend completely replaces its core functionality.
you can rebuild
- Abandoned cart checkout tracking via storefront webhooks
- Automated email recovery drips with customizable time delays
- SMS recovery dispatch with dynamic checkout discount links
- Web push notification subscriptions and trigger rules
- Recovered revenue attribution and basic analytics dashboard
what you lose
- Pre-packaged high-converting email and SMS copy templates
- Turnkey 10DLC brand and campaign registration management for SMS
- No-code visual sequence builder for complex conditional logic
- Built-in unsubscribe and opt-out link handling across channels
- Zero-maintenance email domain warm-up and deliverability management

- 10DLC SMS registration pipeline and carrier trust relationships
- Pre-warmed sending domain reputation for shared infrastructure
