To email or not to email...

I use the computer a lot.  It is probably my most used knitting tool.  I use it to look up patterns and manufacturers.  I use it to track prices, sales, inventory, bills and on and on.  It's also vital to use the computer to send information to customers.  It is the best way to get out class schedules, important events, and coupons. So... What was the question?  Oh yeah.  "Would you like to be on our mailing list?"
