Manage Sendmux from Ubuntu and Linux terminals with the official Sendmux CLI.
Use sendmux to configure local profiles, work with the Management, Mailbox, and Sending APIs, and run email API workflows with JSON output for scripts and automation.
Sendmux gives developers and AI agents a programmable email layer: email inbox API, inbound email API, outbound sending, scoped API keys, MCP support, and SDKs for application code.
This snap packages the published @sendmux/cli release with a bundled Node.js runtime. API operations require your own Sendmux API key. No credentials are included.
