Pricing beyond the initial free mailboxes is not detailed on the landing page, so check the pricing page for current tiers. ## 关键功能与能力 - **Agent mailboxes:** Provision mailboxes on verified domains or a shared myagent.mx address, with clean JSON output that strips signatures and quotes. - **Provider-flexible sending:** Send over HTTP or SMTP using the same mailbox credential as a Bearer token and SMTP password, with Idempotency-Key retries and attachment support. - **Routing controls:** Bind keys to providers, delivery groups, weights, and quota windows so traffic stays inside the boundaries you set. - **Real-time events:** Signed webhooks for delivery and receipt events, an SSE stream for live mailbox clients, and typed change polling for resync. - **Developer tooling:** Official SDKs for TypeScript and Python, a CLI, LangChain and AI SDK integrations, and a hosted MCP endpoint with OAuth. ## 主要用例 - **Triage an inbound support inbox (Support automation):** Give a support or triage agent its own mailbox, feed it stripped-down message content, and let it reply through the same API. - **Wire transactional email into an app (Product engineers):** Send transactional mail from an agent over HTTP with idempotency keys, and receive bounce or reply events via webhooks. - **Spread delivery across providers (Platform teams):** Route sends across multiple providers with weights and quotas so no single account carries all the volume or risk. ## 优势 - One API for sending, receiving, routing, and events - Inbox payloads tuned for LLM token efficiency - Not locked to a single sending provider - Practical developer tooling: SDKs, CLI, MCP, framework integrations ## 局限 - Newer platform, so the surrounding ecosystem and community material are still small - Using your own sending providers puts deliverability and domain reputation on you - Agent mailboxes still depend on correct DNS setup for verified domains ## 常见问题 ### What exactly does an agent mailbox mean? Sendmux provides agent-shaped mailboxes. You can create mailboxes on a verified domain you own or on a shared myagent.mx address, and the agent can both send from and receive at that mailbox. ### How does Sendmux reduce token costs for agents? When your agent reads a message, Sendmux can strip signatures and quoted history by default, with links, headers, and attachment metadata available on request. That keeps token usage down and gives the model actionable content instead of raw HTML. ### Can I route across multiple email providers? Yes. Bind a mailbox key to all of your active providers, to selected providers, or to delivery groups, with percentage weights and second/minute/hour/day quota windows controlling how traffic is distributed. ### Is Sendmux free to try? Two free mailboxes are offered to start. The site is designed for agents to self-onboard: point an agent at the auth instructions or install the Sendmux skills, then connect via MCP or a scoped API key. ### Sendmux 的月流量和增长趋势如何？ Sendmux 目前每月获得 37 访问量，月度环比流量变化为 -2196（增长率 -98.3%）。其主要来源市场是美国（100% 份额），包括每月 12 次直接访问和每月 — 次自然搜索访问。 ### Sendmux 免费吗？它的定价模式是什么？ Sendmux 采用免费定价模式。Sendmux is listed as free, with two free mailboxes available to start and agent onboarding designed to be self-service.
