The problem
You're spending hours on email.
AI can already write your replies. Why is your inbox still a manual job?
Pasting mail into a chat window
Copy the mail, paste into ChatGPT, paste the reply back, fix the formatting. That's not an AI workflow — that's a workaround.
A new mail every ten minutes
Each ping yanks your attention out of whatever you were doing. By lunch you're half through three things and finished with none. Hand the first pass to an AI and your morning starts with focus instead of fragmentation.
The same five mails every week
Filing invoices, answering the recurring question for the dozenth time, drafting the polite no. Routine you'd happily let go of — and exactly the work AI is best at.
What's MCP?
An open protocol for AI to use real services.
The Model Context Protocol was introduced by Anthropic in late 2024 and is now supported by every major AI runtime. inboxmcp speaks MCP — so whichever AI tool you prefer can use your mailbox the moment you connect it once.
What it is
A small open standard for AI assistants to call real services through a structured request, instead of asking you to copy-paste data into the chat.
Where it runs
In Claude, MCP servers show up as Connectors. In ChatGPT, as Apps (Apps SDK) or older Custom GPT Actions. Cursor, Windsurf, n8n and LibreChat all speak the same standard.
How it works
You ask the AI: "draft a reply to Markus." Your AI sends a structured call to inboxmcp; inboxmcp performs it on your real mailbox over IMAP or Microsoft Graph; the result comes back. No copy-paste, no per-tool plugin, no lock-in.
How it works
Three steps, two minutes.
No plugins to install. No mails copied off your mailbox. Your AI assistant talks to your existing IMAP server through us.

How we compare
Why not just use Copilot or the Claude plugin?
Both work — if you live entirely inside Microsoft 365 and never want to switch AI tools. Most people don't.

What you actually say
Real prompts, real answers.
No prompt engineering. You write what you'd write to a colleague. The AI does the work, you stay in the loop.
-
Morning triage
"Catch me up on anything important that came in overnight."
→ The AI scans your inbox, summarises three threads worth your attention, flags the rest as low-priority.
-
Drafting
"Draft a friendly reply to Lisa saying yes to her proposal but pushing the deadline to Friday."
→ A ready-to-edit draft lands in your Drafts folder. You review and hit send.
-
Filing
"Move every invoice from last month into the Accounting folder."
→ The AI finds them, moves them, tells you how many. Audit log records each one.
-
Finding
"Find the PDF Markus sent me about the new contract — I need it open."
→ The AI digs through the right thread, returns a download link for the attachment. Signed URL, 15-minute expiry.

FAQ
Frequently asked questions
What is MCP and how does it work? +
inboxmcp is a hosted connector that lets your AI assistant work with your mailbox without copying mail to a new system. You add one address to your AI client, log in once, and your AI can read and manage your inbox in plain language.
Which email providers are supported? +
Any provider that speaks IMAP and SMTP. mailbox.org, STRATO, IONOS, Posteo, Plesk-hosted mailboxes, Proton Mail (via Bridge), Fastmail, your own mail server. We do not require provider-specific OAuth.
Where is my data stored? +
Your mail stays on your own mailbox. We never copy it. The only data we store is what's strictly required to operate the service: your encrypted mailbox credentials, your audit log, and the OAuth tokens issued to your AI client. All of it lives in our own infrastructure in Frankfurt.
How safe are my IMAP passwords? +
Your mailbox credentials are encrypted before they reach our disk. The component that talks to your inbox is the only one that can decrypt them, and only briefly while it works on your request. Nothing stays in the clear.
What's the difference between Free and Premium? +
Free covers read-only access on a single mailbox. Premium (€2.99/mailbox/month or €29.99/mailbox/year) unlocks the write tools (drafts, moves, sends, flagging, deletion) with no cap on mailbox count. Business (€4.99/mailbox/month or €49.99/mailbox/year) adds a signed DPA, an exportable audit log, and a tax-compliant invoice for German-registered businesses (cross-border reverse-charge isn't supported yet).
Can I cancel any time? +
Yes. No minimum term. Email us to have your account deleted today (self-service from the portal is coming). Credentials, audit logs and tokens are wiped immediately on deletion.
Do you offer a data processing agreement (DPA)? +
Yes. On the Business plan we provide a signed DPA / Auftragsverarbeitungs-Vertrag on request. Required if you're handling third-party email under GDPR.
What about the AI client that connects to inboxmcp? +
inboxmcp itself doesn't keep your mail. But the AI client you connect to it (Claude, ChatGPT, etc.) reads message content to do its job, and what happens to that data afterwards is governed by that vendor's terms, not ours. If your messages contain personal data of third parties, you remain the data controller under GDPR for what the AI vendor does with it. We strongly recommend talking to a data-protection specialist about your specific setup before connecting business mailboxes — what's compliant depends on the AI vendor, the data categories involved, and your own purpose of processing.
Can I get a refund after I subscribe? +
No. inboxmcp is a digital service that we begin providing immediately after payment, so the purchase is binding and no refund is possible once execution starts. You check a box at checkout that makes this explicit. You can cancel at any time to stop further billing, but the current billing period stays paid.
What about the 14-day right of withdrawal? +
Under German consumer law (§356 (5) BGB) you have a 14-day right of withdrawal for digital services — but only as long as performance has not yet been fully provided. At checkout you expressly request that we begin providing the service immediately and acknowledge that doing so waives the right of withdrawal once the service has been fully delivered. Both consents are an explicit checkbox you tick before paying.
