With the EmailBrief integration in ZEIT.IO, you can send any invoice as a physical letter with just one click. The invoice is sent directly to Deutsche Post's printing line, printed, enveloped, stamped, and mailed.
What exactly is Emailbrief.de?
Emailbrief.de revolutionizes the sending of physical letters: Create your letter digitally as usual, for example, as a PDF document, and submit it online. Emailbrief.de handles the entire process – from printing to folding and enveloping to delivery to Deutsche Post. This eliminates the need for you to go to the printer, search for envelopes and stamps, and even the trip to the mailbox. A simple and ingenious service that makes your everyday life much easier.
How does sending via Emailbrief.de work in ZEIT.IO?
ZEIT.IO has direct integration with Emailbrief.de. Once you've created and completed an invoice in ZEIT.IO, a "Send as Letter" button will appear in the preview.
Once this security prompt is confirmed, the invoice document is transferred to the Emailbrief API, and everything else takes its course. The invoice then arrives as a letter to the customer on the next business day.
How much does it cost to send documents via Emailbrief.de?
The prices for sending a document via Emailbrief can be found in the Emailbrief price list. As a general rule, you can assume that sending a black-and-white, one-page document costs €0.91.
If you use Emailbrief directly, you always have to purchase Credit Coins there. Documents can only be sent if you have Credit Coins in your account. With ZEIT.IO, this step is eliminated. If you send a ZEIT.IO invoice as a letter, it will be billed normally via your ZEIT.IO subscription in the following month. ZEIT.IO is making an advance payment here. We have an Emailbrief account with Credit Coins that is automatically topped up. For this advance payment, we charge 30% on the Emailbrief prices. While sending a simple invoice via Emailbrief would cost €0.91, it would cost €1.18 via ZEIT.IO.
