How to send your first letter
Using Pingen is simple and straightforward. This section explains how to send a letter, step-by-step.
Upload the letter
Documents can be dragged and dropped into the browser window or selected by clicking on the dispatch box in the lower left corner. Your letters must be in PDF format and conform to certain formatting standards. You can find more information in the "Letter standards and templates" article.


Send preparation: Letter status after uploading
After uploading, letters are validated by Pingen for mailing. Within a few seconds, you’ll be forwarded to the Send Preparation and see an overview of the letters you uploaded. After validation, each letter is assigned one of the following statuses: "Ready for Sending", "Action Required" or "Invalid".

You can either send the letters now or stop the send process by pressing "Cancel". All letters are saved in the background with their correct status in the letter list and can be sent at a later time. When preparing to send letters, you can adjust the envelope window setting for all the letters you’re sending.
You can’t adjust envelope windows for individual letters here, only an entire batch. It’s best to sort letters by their envelope window position before uploading and upload the right-window and left-window batches separately.
Letter is marked "Ready for Sending"
All letters marked "Ready for Sending" can be submitted for sending in the next step.

"Action Required" status
Letters marked "Action Required" have an issue that must be resolved before sending. Most problems can be fixed in the Pingen App. Make sure the envelope window of the problem letter is set correctly before fixing any other issues. The envelope window setting can be changed in the lower right corner.

The following problems can occur:
- Content in restricted areas. More information
- Invalid paper type. More information
- Issue with the recipient address. More information
"Invalid" status
Letters marked "Invalid" cannot be fixed or sent. There are various reasons why a letter may be marked "Invalid". More information about the "Not available for sending" tab
