our call
Start with Tone Messaging — highest vibe code, weakest moat.
Postscript
You can build the workflow automation engine and Shopify event triggers in two weeks with AI. However, running raw SMS yourself means taking full responsibility for 10DLC carrier registration, TCPA legal compliance ($1,500 fines per violation), and deliverability management.

- Basic SMS campaign broadcast scheduler
- Automated flow triggers (Cart Abandonment, Welcome Series, Order Status)
- Basic subscriber list management and customer segmentation
- Simple Liquid template personalization (first name, discount links)
- Opt-in popups and embeddable forms
what you lose
- Automated TCPA/CTIA legal protections and pre-vetted opt-in wording.
- Pre-configured 10DLC brand registration and direct short code throughput provisioning.
- Shopper AI conversational assistant for automations and response handling.
- Managed service add-ons (Postscript Plus) and dedicated CSM strategists.
- Pre-built flow library for browse abandonment, price drop, and back-in-stock alerts.
