There are a few different problems with Toad World e-mail subscriptions we are looking into.
One problem that should be fixed now is how the link in the automated e-mails you get when subscribed for each forum post behave.
If you click the link at the end of the subscription e-mail from a forum you no longer want to subscribe to that should behave properly now (e.g. "Or Unsubscribe from Toad for Oracle Forum notifications altogether."). It will now launch the Toad World forum page and display a banner informing you that you are no longer subscribed, and the link on the right of that forum web page (Email Subscribe to Forum / Email Unsubscribe to Forum) will be updated as expected.
Sorry this wasn't behaving as it should have.
