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
SendOps is an email workflow and drip campaign platform for onboarding, trial conversion, cart recovery, follow-ups, and win-back journeys. Build on a visual canvas or use SendFlow, the API, or AI agents through MCP. Trigger journeys from product events, segment changes, dates, or recognized website visits; personalize emails, branch on behavior, wait for milestones, and exit on conversion. Webhook steps connect journeys to SMS, push, and your own systems.
Manage contacts, dynamic segments, consent, templates, and broadcasts. Rehearse in shadow mode and track delivery, engagement, and each contact's progress. Send through Amazon SES in your own AWS account with a guided, keyless connection. Existing transactional sending stays independent.
Flat platform pricing with no per-contact or per-email SendOps fees. Free plan available; AWS usage billed separately. Includes message search, deliverability alerts, DMARC monitoring, and inbound email.
