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

SendLit is an open-source email marketing platform for newsletter teams, creators, small businesses, and software platforms that want to manage email or embed sending in their products. It supports visual broadcasts, audience segments, automated sequences, and transactional messages through a REST API. Teams can connect Amazon SES or SMTP providers, manage contacts and templates, and use suppression lists, tracking, and one-click unsubscribe headers. The hosted service offers free and paid plans based on monthly email volume, while Docker Compose supports self-hosting. A TypeScript SDK, MCP server, team-provisioning API, and embeddable React editor support integrations and programmatic workflows. Contacts are unlimited across hosted plans, and email-provider charges are paid separately. SendLit is being bootstrapped; bounce handling and multi-user accounts remain on the roadmap.
