I am getting bombarded by emails FROM: YoshiBlade <bethwyn@algernon.buttskardb.info> or Beautiful Hardwood Floors <Hardwood_Flooring@wealthlegacy.info> or Incredible Indoor Banana Tree <1487182179brad@anasadonat.com> or 'Penny-Auctions' <stephanie_tarin32@filisured.com> or Notification <dominospizza@milanoo1.com> just for example and many others. I would like to be able to block these senders not by their email addresses which constantly change but by the "Nicknames" of the senders, Beautiful Harwood Floors or Notification, etc. But, have not discovered how to do that. Hoping it is simple to do and effective. Please help, this is frustrating to keep getting these unwanted emails and it keeps getting worse. Thanks.
