The Developer's Playbook for Unified Cart Abandonment Recovery
Your brand is losing sales to cart abandonment, and your recovery strategy is making it worse. Separate tools for email and SMS send conflicting messages and offers, creating a disjointed, frustrating experience for customers. This erodes brand trust and significantly lowers your overall recovery rates.
Take back control with a developer-friendly, composable marketing stack. This playbook shows you how to use the open-source Customer Data Platform, RudderStack, as the central brain for your recovery efforts. RudderStack ingests customer events (like an 'Abandoned Cart' from Shopify) and orchestrates a perfectly timed, consistent sequence of messages across best-of-breed tools like MailerLite for email and Twilio for SMS. The result is a single, intelligent campaign that respects the customer journey, avoids vendor lock-in, and maximizes conversions.
Expected Outcomes
- Eliminate conflicting messages by creating a single, orchestrated recovery journey.
- Increase cart recovery rates and overall revenue.
- Achieve full ownership of your customer data and marketing logic.
- Build a flexible, future-proof stack using best-of-breed, API-first tools.
- Improve customer trust by delivering a cohesive, intelligent brand experience.

The Workflow
Integration Logic
-
RudderStack Event Stream
This integration uses RudderStack as the central Customer Data Platform. User interaction data is captured from a source (like a website or mobile app) using a RudderStack SDK. When `identify` calls are made, RudderStack creates or updates subscriber profiles in MailerLite. When specific `track` events occur (e.g., 'Signed Up', 'Purchased Product'), RudderStack routes this data to trigger actions in the connected tools. For MailerLite, this could mean adding a subscriber to a specific automation or group. For Twilio, this could trigger a transactional SMS message, such as an order confirmation or a welcome text.
