Unitpost
Email and SMS API for developers and AI agents, with an MCP server
Unitpost is an email and SMS platform for developers and the AI agents they build. Send transactional email, campaigns and SMS over a REST API, nine SDKs, SMTP or an MCP server. Cursor, Claude Code and other MCP clients connect with OAuth and get the same actions as the dashboard. Unit, the built-in assistant, builds templates and campaigns and asks before anything sends. SMS reaches 177 countries. One flat monthly price is your sending balance. The free plan includes 5,000 emails a month.
