Courtesy reply mail,
is a type of mail in which a business sends pre-printed, self-addressed envelopes
to customers, who then affix postage stamps
to the envelopes or postcards and mail them back to the business. Alternatively, the business can disseminate the envelopes or postcards with stamps already affixed, similarly to metered reply mail
Courtesy reply mail differs from business reply mail
in the manner of payment of postage, namely, by stamp when the mail is sent, rather than by the permit holder when the mail is received. Courtesy reply mail is typically used when a response is practically guaranteed, e.g., bill payments.
In the United States
, the United States Postal Service
specifies that the envelopes or postcards for courtesy reply mail should be printed with a FIM
A code. The POSTNET
bar code can be printed on the envelope or postcard; alternatively, it can be printed on a payment coupon so that the bar code is visible through the window of a window envelope when the payment coupon is inserted.
