Dear Subscriber,
As requested, I have deleted your e-mail from my subscriber list. I am sorry for your decision to cancel your subscription and hope that you may rejoin some time in the future. If it would not be too inconvenient would you help me out with three important questions. If some reason, I have done something that prompted your decision to unsubscribe, I apologize. I don't want to continue making the same mistake. Your input would be greatly appreciated.
I unsubscribed because I am not allowed to receive e-mails at work.
I unsubscribed because I am not interested in your newsletters.
