About

Ringmaster is a hosted lifecycle email platform for software teams using application events and AI agents to coordinate customer messaging. Applications send events through a REST API; AI agents connect over the Model Context Protocol (MCP) to build and manage email flows, segments and campaigns. A dashboard provides access to the same flows and results. Features include event-triggered sequences, audience targeting and campaign management. Server-side controls support idempotent events, duplicate-send prevention, daytime delivery, consent checks, unsubscribes and suppressions. Flows can skip recipients who completed the intended action. Teams can use Ringmaster for onboarding, product education, re-engagement and other lifecycle messaging. The monthly plan includes unlimited flows, campaigns and segments and 10,000 emails; additional volume is available on request.

About

Unitpost is an end-to-end customer communications platform. You describe the workflow you want (a welcome series, shipping updates, a win-back campaign, etc.) and Unitpost builds it for you: ready to run across email, text, and WhatsApp. Today we support transactional + marketing email with a hybrid template system (visual + code), contacts, segments, campaigns and automations. The foundation is built horizontally from day one: one contact model, one event system, one pricing model (shared sending balance), and every action works the same way in the UI, via API, and through our agent (Ask Unit). We are not building another email tool. We are building the messaging layer that replaces the pile of tools teams currently stitch together and can be prompted for result, not manually built.
