I ran for one brief and painful period the newsletter mailing list for the
Travelocity (http://www.travelocity.com/) Web site. The initial list was
seeded with ~9000 addresses of people who had filled out marketing surveys and
checked "yes, I want to get more information by e-mail". Between the time we
put up our subscription form (early August) and when I delivered the October
1st edition, we had grown to ~25,000 subscribers and were adding a couple of
hundred a day, about 1,000/week since weekends were much slower. Delivering
that first newsletter with a UNIX mailer (zmailer) was nearly an all-day
hands-on affair, and enough to convince me that industrial-grade tools would
be worth the money...
I nearly quit that job when they tried to order me to send UCE to the entire
registered user base of Travelocity (~250,000 users), and I did ultimately
leave to go work for someone who offered me a job when I vented on the
zorch mailing list about being asked to spam.
