This is the email I just received from Yahoo!
Yahoo! sent me an email to say that they’re renaming their calendar and notepad by adding “All-New” in front of them?
I don’t use Yahoo! Calendar and Yahoo! Notepad. Where’s the unsubscribe button? Oh wait, there is none.
Lesson learned: Make sure emails are adding value versus destroying value. While sending an email may not have a monetary cost, there are costs for sending bad emails. Perhaps the only way to get off this list is to delete my Yahoo! account, which I don’t really use anyway.
