> That's why I said the email should contain info about the sender -- there should of course be a way to contact them. That implies a level of manual effort on the part of the recipient that's unreasonable. I have no relationship with these companies. They did not verify the email address before starting to send a stream of supposedly transactional messages to it. They should be happy that I'm willing to click unsubscribe when available, because the alternative is to set up a mark-as-spam filtering rule that'll hopefully tank their sender reputation. Writing them via a contact form begging to be removed is not an option.
