Go big with letter-size mail

A letter-size mailpiece is the most economical for postage. Common sizes include the #10 envelope or 8.5 x 5.5 postcard. Did you know you could design a mailpiece that measures up to 11.5 inches wide by 6.125 inches high - and still qualify for letter-size rates? This larger, letter-size piece stands out in the mailbox the same as a 9x12 flat but they mail for much less. They can be designed as postcards, selfmailers or in #11 stretch envelopes.
