Can a prompt replace Drip?

Build a single-trigger e-commerce email automation: a webhook receiver, a delay-and-check job, and Amazon SES for sending. Stack: Next.js API routes, PostgreSQL for tracking pending sends, a job queue (BullMQ with Redis) for the delayed check, Amazon SES.

Core loop: expose a webhook endpoint the store platform calls when a checkout starts (Shopify's `checkouts/create` is a good concrete target — pick one platform rather than trying to support every webhook shape). Store the cart ID and customer email, and schedule a delayed job (e.g. one hour later) that checks whether an `orders/create` webhook for the same cart arrived in the meantime. If not, send one reminder email through SES with a link back to the cart. Log every send and whether a purchase eventually followed, for a basic "did this work" view — not full revenue attribution, just a yes/no per sent email.

Requires a store platform account with webhook access (Shopify's free development store is enough to build and test against), Redis for the delayed job queue, and an AWS account with SES access plus a verified sending domain.

Do not build: additional trigger types beyond cart abandonment, branching sequences with multiple steps, cross-platform webhook normalization (supporting Shopify, WooCommerce, and others all at once), or revenue-attribution reporting beyond a simple did-it-convert flag — each of those is a legitimate expansion, but none of them belongs in a build that's honest about doing one trigger well.
