According to the CAN-SPAM Act of 2003...
"Your email must give recipients an opt-out method. You must provide a return email address or another Internet-based response mechanism that allows a recipient to ask you not to send future email messages to that email address, and you must honor the requests. You may create a "menu" of choices to allow a recipient to opt out of certain types of messages, but you must include the option to end any commercial messages from the sender."
Well, lo and behold, Mamasource does provide an unsubscribe link, but guess what? YOU CAN'T ACTUALLY UNSUBSCRIBE! This link takes you to an email preferences page, where you can change the following:
Email me a Daily Digest of the latest requests, news, and activity on Mamasource.
Email me each time a new request is made on Mamasource.
Email me each time I receive a new response to one of my own requests.
Email me each time I receive a new personal message.
Does anyone see an unsubscribe option here?
Check out the "unsubscribe" page for yourself
It is plain to see that they do not allow you to enjoy a "one-click opt-out" or let you unsubscribe without hassle. They do, however, make it very easy for you to unknowingly spam all of your friends, relatives, and acquaintances with trees and flowers with a simple click!
See the CAN-SPAM ACT of 2003 here.
If you are sick of getting these emails, I suggest you forward them in their entirety to firstname.lastname@example.org!
Stop these people from gathering your information and harvesting your email address books.
It just ain't right!
