Mailtea is an agent-native email platform for sending newsletters and transactional messages from a single place. You design campaigns in a visual studio that shows exactly what subscribers will see, manage your audience, track performance, and publish a public archive on your own domain. A clean API, official SDKs, and a full MCP server let AI agents draft, schedule, segment, send, and measure email with the same capabilities as a human operator.Domain authentication, automatic list cleaning, and one-click unsubscribe are built in to support good deliverability. A free plan includes the complete designer, website hosting, 3,000 emails per month, 1,000 contacts, and full API/MCP access.
