Just got an email from HP printer service, I will paste the first part here:

Dear Customer,

 *** Please do not reply to this email.  This email is not monitored. ***

  

One of our Technical Support Specialists will be responding to your inquiry. It is our pleasure to be of service to you and thank you for choosing Hewlett-Packard, as your preferred vendor.

Imagine, HP does not want to hear from their customers, who, collectively, make their jobs and company possible.  If you are going to do emarketing successfully, you will need to have a conversation, a dialog with your customers, not a rude monologue, where you inform the "dear customer" that you don't want them to reply to you.

Internet marketing requires a little more class than telling your customers that you are not interested in them  Have you ever sent an email to a friend or relative and opened with "don't reply to me, I don't care to hear from you?"  They may not be your friends for long if you do

Interactive marketing, is well,  interactive.  A "do not reply" message is rude.
