Sendmux provides a unified email inbox API specifically designed for AI agents, streamlining communication by handling both sending and receiving.

What it does

Sendmux empowers AI agents with a robust email infrastructure, enabling them to create dedicated inboxes, send emails through their own providers, and manage outbound routing with advanced controls like quotas and weighted delivery. It offers automatic failover at scale, ensuring reliable communication for AI applications.

Key features

Agent-shaped inboxes — Create mailboxes on verified domains or shared myagent.mx domains, with options to receive raw messages or clean JSON, automatically handling signatures, quotes, links, headers, and attachment metadata.
Outbound email sending — Route outbound emails through your own SMTP providers, offering flexibility and control over deliverability.
Advanced routing controls — Implement quotas and weighted delivery to manage outbound email traffic efficiently.
Automatic failover — Ensures continuous email service by automatically switching to backup providers if the primary fails.
Unified API — A single API surface for managing inbound mail, agent mailboxes, routing, and delivery events.

What makes it different

Unlike traditional email services that require complex stitching and separate APIs, Sendmux offers a purpose-built, all-in-one solution for AI agents. It addresses the challenges of LLM token consumption by stripping unnecessary email content and provides unparalleled provider flexibility, allowing you to use your own sending infrastructure.
