What is a Windowed Letter?
The Windowed Letter option is a commonly used mail type that allows you to send mail via First Class or Certified mail. Here are the specs:
- Choose between First-Class (no tracking) or Certified (tracking plus signature)
- Windowed Envelope. Addresses are printed onto a cover sheet that will display the addresses (and the Certified tracking barcode if applicable) through the windows of the envelope
- Great for generic or variable data documents that need to be sent to 1 or thousands of recipients
