Not possible in Gmail, but you may find a Chrome add in. Just be careful with add ins; Google can treat these as spam, and lock your account as well. They seem to be tightening up on this. For what it is worth, CR follows:- "Google themselves do not maintain blacklists / whitelists on your behalf. Therefore there is no way to actually stop these emails coming to you, or having Google return automatically to the sender. To avoid reading/seeing any sender:- You can mark these messages as Spam *https://support.google.com/mail/answer/1366858?hl=en <https://support.google.com/mail/answer/1366858?hl=en>* *or* Filter to be deleted on receipt - (just make sure that you do not delete anything important, as you will be unable to get it back!) *https://support.google.com/mail/answer/6579?hl=en <https://support.google.com/mail/answer/6579?hl=en>* *or* Use the new Google "Block Sender" feature *https://support.google.com/mail/answer/8151?hl=en <https://support.google.com/mail/answer/8151?hl=en>* If using an Android device you can click on the three horizontal dots in Gmail app, to make similar Block/Unsubscribe settings. These choices, if made here, can only be reversed on the Web interface. Never use the "unsubscribe" feature on Spam emails. Has no affect whatsoever; merely tells the spammer that they have a "live one" on the hook, and your spam will increase. As well as that, your address may be on-sold to other spammers. If mails are harassing/offensive in some way, you should discussing these to your local law enforcement authorities. You can also report harassing emails to Google, if the offender is using a Gmail account; Google may or may not take action, and usually will not reply to you. *https://support.google.com/mail/answer/29434?hl=en <https://support.google.com/mail/answer/29434?hl=en>"* -- You received this message because you are subscribed to the Google Groups "Gmail-Users" group.
