In many cases, you won’t have to e-mail a person directly. Instead, check the body of your latest mailing list e-mail and look for an “Unsubscribe” or “Opt-Out” link at the very bottom. Clicking this link will open a web browser window and take you to either a confirmation page or a communications preference page, which lets you select what type of e-mails you wish to receive from the group in the future. To completely unsubscribe, uncheck all of the options and submit your update.
