Pitney Bowes Insertor
Yes, people do still use traditional surface mail suprisingly. If you have a bit of volume each month, an insertor from Pitney Bowes may be worth investigating. The Di 2003 pictured will take up to 3 items, fold them and insert into an oversize DL envelope for you, and is good for up to 900 items per hour. Plus, it also seals the envelope once you're happy with a test piece. Often sold with a postage meter, they can make your next monthly statement run or campaign much more efficient.
