Lettr AI Automation + Broodle Studio
Lettr is an email and messaging platform for transactional delivery, templates, audiences, campaigns, domains, and webhooks.
Lettr joins Broodle Studio’s Composio-powered connector network as a full agentic integration: your AI agent can attach contacts to lists, bulk create audience contacts and cancel scheduled email — 60 actions in total. Every step is approval-first, isolated to your account, and chainable with the rest of your stack.
Free tier included · Every action asks for your approval before it runs
