Windowed envelopes are a suitable replacement to windowless envelopes, with only a cosmetic difference:

  • Documents are inserted with a coversheet that includes the addresses.
  • The coversheet is printed and added automatically to your mailing.

  • Coversheet Cost: Previously, using a coversheet added cost, but the price has been reduced by 2 cents.
  • No Coversheet Savings: If you format your document so a coversheet is unnecessary, you can save even more. Click here to learn more.

Mail Open Rates

There is no evidence to suggest that windowless envelopes result in higher open rates compared to windowed envelopes. This change should not affect your mail's open rates.
