Drip

Drip is built for ecommerce lifecycle marketing: storefront integrations, dynamic segments, onsite campaigns, automations, and product-triggered personalization. It can serve non-ecommerce teams, but the deepest value comes from online-store events and revenue reporting.

An agent stack treats email as a two-way primitive. Inbound has to arrive as structured JSON a tool call can consume, sends have to be safe to retry when a model loop repeats itself, and every action needs an audit trail. A provider without inbound parsing only solves half the problem.

Against inbound parsing into tool calls and model-generated sends that must not duplicate, Drip covers webhook coverage, event stream, batch sending, and multi-tenant support, and does not cover inbound parsing, idempotency keys, operating track record, and SDK breadth. Whether that gap matters depends on how central those are to the build.
