Here's the thing: email wasn't built for AI agents. It was built for humans clicking send. So we built Sendmux.

Sendmux is an email API that lets AI agents send, receive, and route email from a single platform. One platform. Your providers. Your mailboxes. No glue code.

Connect Gmail, Outlook, SendGrid, Mailgun, Resend, Amazon SES, or any SMTP-compatible provider. We handle routing, failover, and monitoring. Weighted distribution shifts traffic automatically when a provider struggles. Quotas at four levels keep you inside rate limits without thinking about it.

When email arrives, most platforms hand your agent a raw HTML blob. Parsing that burns thousands of LLM tokens. Sendmux converts incoming email into clean structured JSON. Your agent reads it like any other API response. Up to 80% fewer tokens consumed per message.

50M+ emails sent. 100+ teams building with us. Start free.
