About

Primitive is email infrastructure for AI agents, giving them a one-line 'primitive chat' verb to send a message and wait for a threaded reply, plus a managed subdomain that runs a JavaScript handler on every inbound message. It handles the full protocol surface — inbound MX, SPF, DKIM, DMARC, TLS-RPT, bounce processing, and IP reputation — so agents do not need SMTP credentials or their own mail server. Based in San Francisco and backed by Y Combinator, its inbound MX implementation and SDKs are open source on GitHub.
