It brings together campaign and automation tools, transactional messaging, sales management, and a customer data platform so marketing, sales, and support teams work from a single source of truth. Channels cover email, SMS, WhatsApp, web and mobile push, live chat, chatbot, VoIP phone, and mobile wallet, while the CRM side offers custom pipelines, sales automation, and meeting scheduling. Integrations extend to more than 150 tools including Shopify, WordPress, Stripe, and Zapier, and developers get an open API, SDKs, and detailed guides. Brevo has moved to an AI-first approach with its Aura agents: a Marketing Agent generates copy and auto-segments audiences, a Sales Assistant enriches contacts and drafts outreach, a Data Analyst answers questions in plain language, and a Conversations Agent summarizes chats and tailors replies. A free tier is available, with paid plans scaling by email volume and contacts. **Pricing & Plans:** Freemium. A free plan is available with daily sending limits and basic features; paid plans scale with the number of contacts and monthly email volume, and higher tiers add advanced automation, loyalty, and enterprise-grade security.

Sendmux collapses that into a single API surface. It covers outbound mail, agent mailboxes, routing controls, and delivery events, so an agent can send, receive, route, and react without juggling separate accounts and bills. A key design decision is that inbox data is formatted for machine consumption. Gmail and Outlook typically return full HTML bodies that burn thousands of tokens before the agent gets to the actual content. Sendmux strips signatures and quoted history by default and exposes links, headers, and attachment metadata only when asked, so the model spends its budget on the message rather than the markup. On the sending side, Sendmux is deliberately not a single-provider lock-in. A mailbox credential works as both a Bearer token for HTTP and a password for SMTP, and routing can be bound to specific providers, delivery groups, weights, and quota windows. Events arrive through signed webhooks, an SSE stream, or typed change polling, which means agents can react in real time rather than running polling loops. SDKs for TypeScript and Python, a CLI, framework integrations, and an MCP endpoint make it straightforward to wire the whole thing into an existing agent stack. **Pricing & Plans:** Sendmux is listed as free, with two free mailboxes available to start and agent onboarding designed to be self-service. Pricing beyond the initial free mailboxes is not detailed on the landing page, so check the pricing page for current tiers. - **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. **Strengths:** 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 **Limitations:** 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 [Profile (Markdown)](https://openaitools.app/tool/sendmux.md) ## Frequently Asked Questions ### How do Brevo and Sendmux compare in monthly traffic?
