SadaSend Gives AI Agents Email Without the Whole Account

Why it surfaced

SadaSend treats agent permissions as the product: a key can send and read, but cannot mint credentials or delete a domain. The homepage makes the control model unusually concrete, down to staging allowlists, human approval, and a refused `keys.create` request.

A transactional email API and hosted MCP server with scoped keys, recipient allowlists, approval mode, and dry runs for AI agents.
