What SOMMON Office does
SOMMON Office lets an AI assistant send real letters for you. Deutsche Post delivers them to recipients in Germany and 217 other countries, as ordinary letters or as registered mail (Einschreiben) with tracking. You can live anywhere. Typical letters go to customers and suppliers abroad, authorities, courts, embassies, landlords, insurers, family and friends: invoices and payment reminders, applications, objections and appeals, cancellations and formal notices.
How do I connect it?
In Claude, add a custom connector with the URL https://office.sommon.de/mcp under Settings, Connectors. Sign in with your email address and a password; the first sign-in creates your account. Any other assistant or app that supports remote MCP servers over Streamable HTTP connects the same way. Agents without a browser use an API key from the account page as a bearer token.
What happens when I ask for a letter?
Say what you need, for example: “Send Atelier Lumière in Paris a reminder about our unpaid invoice 2026-114, as registered mail.” The assistant drafts the text with you and registers sender and recipient (create_letter). The service typesets the letter as a business letter (submit_letter_text) or checks your own PDF (submit_letter_pdf) and returns a preview with a specimen stamp and the price. You approve and pay on our page (create_payment_link), or the assistant pays from your balance (purchase_letter). The letter is dispatched on the next working day, and get_letter_status reports the Deutsche Post tracking.

What does a letter cost?
Up to three pages within Germany €2.49, sent for you, or €1.49 if you print it yourself (senders in Germany). To other countries €2.79. Registered mail: €4.84 within Germany, €6.49 abroad. Longer letters cost more, see the price table. Paying from a balance saves €0.20 per letter. The preview shows the final price before you pay.
I live outside Germany
Your letter is sent by Deutsche Post with German postage. The return line names you care of our address, so an undeliverable letter reaches us; we tell you, keep it for 30 days and then destroy it securely.
Letters that need a handwritten signature
Automatically sent letters carry your name but no handwritten signature. That is enough for most letters to authorities and companies. A few documents legally need a signature by hand, for example certain employment or tenancy terminations. For those, senders in Germany choose self-printing, sign the letter and post it.
Registered mail and proof of delivery
Within Germany, Einschreiben Einwurf has a tracking number and documented delivery to the letterbox; a return receipt with the recipient's signature is available. We email you the Deutsche Post posting receipt and the delivery status. Einschreiben International has a tracking number too; for many countries tracking ends when the letter leaves Germany. Ordinary letters cannot be tracked.
Languages
Letters are typeset in German, English, French, Spanish, Italian, Dutch, Polish or Portuguese. A finished PDF can be in any language. The approval page, emails and invoices follow your browser language, German or English.
The address is wrong
Before approval, ask the assistant to create the letter again. After purchase the postage is issued for that address. Write to us, and we will request a refund from Deutsche Post as long as the letter has not been posted.
How do I delete my data?
Through the assistant or by writing to us. Details are in the privacy policy.
