Nobody is a bigger believer in online and e-mail marketing than me. It works, its easy and inexpensive, and it can be highly interactive with the receipient.
But TicketMaster has apparently crossed the line? The folks at Church of the Customer would say "yes". Read about it here...its worth it.
The lesson here for sales professionals: Be careful about how you market yourself and your products by e-mail, and respect the right for your prospects to opt out of your messages. There's no need to force a sales pitch down their throats...it doesn't work very well in the field (cold calling anyone?) and it doesn't work online.
