Description
Zetteldesk lets Claude write and send real paper letters. Describe what you need, or hand over your own PDF: Zetteldesk checks the letter, shows you the recipient and the exact price, and after your confirmation the letter is printed, put in an envelope and posted. Typical uses: a cancellation letter (Kündigung), an objection (Widerspruch), a letter to a landlord, an authority, an insurer or an employer, a formal notice, a registered letter (Einschreiben), or a letter to someone who does not use email. It does not send email. Letters are printed and posted in Germany and can be delivered to almost any country. International letters cost more, at one price for every country, and the price is always shown before anything is sent. Tools: compose a DIN 5008 letter from plain text, validate an uploaded PDF (A4, address window, not encrypted), get a price quote, send the letter, follow its status, cancel it within moments of sending, and check your balance. You need a free Zetteldesk account (sign in with OAuth). Letters are paid from a prepaid balance that you top up on zetteldesk.com. The connector has no payment tool, and sending a letter costs money and cannot be undone once it has been handed to the printer. Letter PDFs are stored encrypted and deleted after 90 days.
