Growth Engineering Playbook

The error notification is the workflow

An event-driven abandoned-cart recovery workflow, made inspectable. It replays invented carts for the Northstar Outfitters store and shows the parts that decide whether automation earns money or quietly loses it: suppression, wait states, retries, failures, and human approval — not just "send an email after two hours." Deterministic, no real sends.

Loading cart data…

Delay before first email

Max retries

Approval mode

Suppression

Workflow Timeline

One cart from checkout to outcome — decisions, waits, sends, and recovery.

Recovery Email Preview

Rendered from cart + catalog data. Nothing is sent; the recipient is a hashed token.

Decision Log

Every rule the workflow applied, and how often it fired.

Error & Retry

A failed provider call, its retry schedule, and the escalation. Failure is handled, not hidden.

Human Approval Queue

High-value carts wait for a person under human-approval mode. Approve one to release it.

Business Impact

Recovery earned, bad sends avoided, and failures caught before silent loss.
