Sendmux is an email API for AI agents that combines real mailboxes with multi-provider outbound sending. Agents can send, receive, reply and read cleaned message content through APIs, webhooks, real-time events, MCP, SDKs and a CLI. Teams can route outbound mail through their own Gmail, Outlook or SMTP providers, with quotas, health checks and automatic failover. Pricing is usage-based, with no per-mailbox fees. Start with a free @myagent.mx mailbox.
Drop-in web component for collecting feedback on any website. One custom element with Shadow DOM isolation, dark mode, keyboard support, and SSR-safe imports.
Sends structured JSON to your endpoint, any webhook, or a server-side Sendmux relay. Your downstream process classifies issues, groups duplicates, routes to support, or creates GitHub issues.
Feedback becomes email your AI agent workflow can act on. Not another dead spreadsheet.
Fully open source under MIT. Works with any stack.
