I use Gmail and have found my name added to a work mailing list without my consent. Now, I keep getting emails from various colleagues who simply send an email to the mailing list address. There is no way to unsubscribe because no one knows who created this group email and the emails do not mention unsubscribe option either.
I cannot block incoming emails based on the sender because it would block a number of colleagues. Is there a way to block the emails based on the "To" field? This way I can continue receiving other emails from all colleagues except the one they send to this mailing list I want to unsubscribe from.
Any suggestions will be greatly appreciated.
