What is a remittance envelope?
A remittance envelope is a business reply envelope constructed with
a large flap that nearly covers the entire back of the envelope.
This extended flap allows more space for printing additional
information and reducing the cost of an extra insert.
What is a dual purpose mailer?
Like a remittance envelope, a dual purpose mailer, sometimes called
a two way mailer or hitchhiker envelope is also a business reply
envelope constructed with a large flap that covers the entire back
of the envelope. It is perforated, so the recipient can tear it and
place it inside, and mail it.
