Abstract:

A lot of STC chapter and SIG mailings are done the old-fashioned way: envelopes stuffed by hand, and stamped manually or--occasionally--with a stamp machine. That's an awful lot of work, and expensive too. When I confronted this problem a few years back for my current employer, some research revealed a solution that eliminated the annual pressganging of volunteers to stuff envelopes and also saved us a fair bit of money.
