What Is an Envelope Endorsement?

An endorsement is a customizable text field that prints on the bottom left corner of return envelopes. It allows you to include:

  • A general message (e.g., “Time Sensitive Documents Enclosed”)
  • Instructions (e.g., “Please Return by [Date]”)
  • Signature lines (e.g., “Signature Required ______________”)

This feature adds a professional and functional touch to your return envelopes, ensuring that recipients take immediate and appropriate action. Endorsements will appear as shown here:
