Ah yes, I love the aroma of cynicism in the morning!
No busy manager or owner (who hasn’t even purchased the product)is going to appreciate an automated flow of an individualized sequence of emails and information sources, educating him and maintaining constant contact.
It would be safe to assume the vast, vast majority of emails sent by this software are immediately trashed or sent to the spam filter. It would be also safe to assume when the default option on your web site is to send emails updates the purchaser doesn’t want the email they are going to be flooded with. Walk up to anyone with purchasing power at a company and ask them if they want emails promoting products after their purchases. 99 out of 100 will say no, yet 99 out of hundred get them.
