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.

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.

Yes, as many as you like. Each one is its own mailbox in inboxmcp, and your AI can work across all of them in the same conversation. That's the difference to Claude's built-in Microsoft 365 connector, which signs in with a single Microsoft login: shared mailboxes that login already has access to come along, but a second, independent account does not. We bill per mailbox, and Premium and Business have no cap.

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.

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.

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). Team (from €29.97/month) bills per user instead of per mailbox, includes everything in Business, and adds team mailboxes with per-member permissions.

The team plan bills per user instead of per mailbox. The entry price is €29.97 a month and includes 3 users; every additional user is €9.99 a month. Each user brings 3 mailboxes, and they form one shared pool: with 3 users you can connect 9 mailboxes, no matter who uses them. Every mailbox beyond that is €4.99 a month. The team plan needs your own company domain, because invitations only go to verified domains. Billing is monthly only, by card or SEPA direct debit.

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.

Yes. On the Business and Team plans a signed DPA / Auftragsverarbeitungs-Vertrag is included. Required if you're handling third-party email under GDPR. On Team the DPA is signed by the organisation and covers its team mailboxes.

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.

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.

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.
