All email providers have a block facility. They vary in method from provider to provider, and some are more convoluted to apply than others. Outlook is easy, but BT is a little more complex and requires the copy of the url to the correct sub menu. If you post your provider someone will talk you through it.
Just a thought Johnny. If these emails are coming from a bona fide website that is mail shotting you with offers, some of them have an unsubscribe option at the top of the emails that you can activate. Thereby stopping the continuous mailing.
I am with Outlook, and none of their category's work for me, block, report phishing scam, and junk I dont trust e-mails if they say, to unscribe, click here, as was told they sell the address.
Outlook works trt. The problem is some of the unwanted senders have multi email addresses, sometimes with a dot or comma difference in them. You have to keep blocking them until you have worked your way through their list of options. Pain I admit. My son had access to my lap top when we were on our holidays and used my microsoft account. Man did I get a load of unwanted mail. He got a big earache.
Yaawwn I know Guilbert and so does he. But he didn't because he just was too laissez faire after a long day. I have such accounts set up on my desktop for guests and family when the visit.
