Even in this day of computers when each of our sales representatives has one on his or her desk and on their cell phone,  we still communicate using the USPS for some items.  Many of our clients prefer to get hard copy sales letters instead of an email about our products.  We now have a software program that gives us templates for these letters whether they will be sent out by email or by snail mail.   What it does is take the work out of writing them and insures that we have a constant and reliable source of new material to send out.
