Unsubscribe Option on Letters?

[Ryan Heenan]

Just finished my first direct marketing campaign based on a lot of advice from this group - thanks for all of the great tips!

As I'm sure most of you know all too well, there were more than a few angry phone calls asking to be taken off the list for future mailings.

My question to you is - how do you think something like an unsubscribe option would be received? Something like this in smaller text at the bottom of the page:

"I apologize if this letter isn't of interest of you. If you text your address + 'unsubscribe' to the phone number listed, I'll be sure never to mail you again. Thanks for understanding."

Does this make it TOO easy to unsubscribe (i.e. taking someone off the list that may be more receptive after 3-5 mailings?) What are your thoughts?
