Bulk Letters: How a PDF and an Address List Become Mail

How to post hundreds of letters from a PDF template and a CSV address list, without printing, folding, or going to the post office.

By TruegateX Support Team

Announcing price changes, sending contracts, writing to customers: anyone who mails a lot of letters quickly loses a full working day to the printer, the folding machine, and the post office. With digital letter delivery it all happens in one pass.

What you need

  • A PDF template of your letter, with placeholders for name and address if needed
  • An address list as CSV, for example exported from Excel

How the sending works

  1. Upload the PDF template in the customer center.
  2. Import the CSV file with the recipient addresses. You map the columns (name, street, ZIP, city) with a click.
  3. Choose the delivery options: standard letter or registered mail, color or black-and-white printing.
  4. Check the preview and approve.

From there we take over: every letter is printed, folded, enveloped, stamped, and handed to the postal service. You can track the status of every single letter in your sending archive.

What to watch out for

Keep the address area free. The recipient address must sit in the envelope window. Use our template or keep the area at the top left of the document free.

Special characters in the CSV. Export the list as UTF-8 so that "Müller" does not turn into "Müller". In Excel, choose "CSV UTF-8" when saving.

Use registered mail deliberately. A standard letter is enough for most correspondence. For deadline-critical or legally sensitive letters, registered mail is worth it; you then also get the delivery record.

What does it cost?

The price consists of printing, envelope, and postage and is billed per letter. For bulk letters you see the total cost in the preview before approving.
