Simply forward all of your unwanted marketing emails to us, and we will unsubscribe you.
Most email clients have the ability to select and forward multiple emails -- we reccomend you do that. (Thunderbird .eml files are supported, too.)
We will manually unsubscribe you. If there are multiple marketing email chains -- *then we will unsubscribe you from all of them*.
For example, Newegg.com has multiple email chains.
