## Maildep

Maildep combines conventional mail server hosting with agentic AI processing. Each mailbox is a normal IMAP/SMTP account that works with familiar clients such as Outlook, Gmail, Thunderbird, and Spark, complete with SPF, DKIM, DMARC, TLS/SSL, spam filtering, and auto-discovery. What sets it apart is what happens when mail arrives: the server runs it through a large language model to summarize the message and pull out embedded reports, meetings, tasks, invoices, and bills, and it can generate draft replies too. Maildep estimates this automation can save staff roughly two hours a day.

The platform is deliberately model-agnostic. You supply your own API keys for OpenAI, Azure, Anthropic, or DeepSeek, or wire in models from Groq, SambaNova, OpenRouter, and even a self-run Ollama instance. Usage of those APIs is free of charge on Maildep's side; if you would rather not manage your own keys, you can buy token plans that are shared across your mailboxes. Administrators get per-mailbox toggles, custom prompts, ignore lists, and performance and token-usage reports so AI behavior stays under control.

Hosting is delivered from six data centers across the US, UK, EU, Japan, Singapore, and India so you can keep data within a chosen jurisdiction. Plans range from a low-cost tester mailbox up to large multi-domain business accounts, and for organizations that want full control there is a semi-self-hosted small-business tier and a fully self-hosted, Kubernetes and container-based installation with a management control panel and a year of maintenance.

**Pricing & Plans:** Freemium with a free trial and paid tiers. Mailbox hosting runs from $0.50/month (5 GB Tester) through $2.5/month (Starter, 25 GB), $12.5/month (Professional, 120 GB), and $75/month (Ultimate, 700 GB), with a 15-day free trial and no payment required to start. Small-business semi-self-hosting is $150/month and full self-hosting is $1,500 per installation. AI token plans are sold separately ($1 for 2M, $3 for 5M, $8 for 10M tokens), while using your own API keys is free; 200,000 free ChatGPT tokens are included per mailbox. Extra storage is $1/GB per month and region changes cost $80.

- **AI-connected IMAP and SMTP hosting:** Standard business email with IMAP/SMTP, SPF, DKIM, DMARC, TLS/SSL, spam filtering, and automatic mail server discovery that works with Outlook, Gmail, Thunderbird, and Spark.
- **Automatic extraction on arrival:** Incoming messages are automatically summarized and mined for reports, meetings, tasks, to-dos, and invoices and bills as they arrive.
- **Bring your own AI model:** Point mailboxes at OpenAI, Azure, Anthropic, DeepSeek, Qwen, Groq, SambaNova, OpenRouter, or your own Ollama models, using your own API keys.
- **Six regional data centers:** Choose from six data centers in the US Central, United Kingdom, European Union, Japan, Singapore, and India.
- **Granular mailbox-level controls:** Enable or disable AI per mailbox, add custom prompts, maintain an ignore list, and review AI model performance and token usage reports.

**Strengths:** True business email hosting, not just an AI layer on someone else's mailbox; Model-agnostic: use your own OpenAI, Azure, Anthropic, DeepSeek, or local Ollama keys; Automatic summarization and extraction of reports, meetings, tasks, and invoices on arrival; Six regional data centers for jurisdictional control, plus fully self-hosted option

**Limitations:** AI features require you to supply your own API key (OpenAI, Azure, Anthropic, DeepSeek, etc.) or buy token plans separately; Setup assumes you can manage DNS records for your own domain and understand mail server concepts; Self-hosting and small-business tiers carry significant up-front commitments ($150/month or $1,500 per installation); Regional data center changes and extra storage incur additional fees, which can add up

## Sendmux

Agents that need to handle email usually end up stitched together from two or three services: one platform for sending, another for receiving, and a pile of glue code to reconcile them. 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
