Overview
In the maker's words.
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.
