Question: I have a company that keeps emailing me. I have blocked them but they use a different URL or address each time they send out messages so they get through. The title of the email is always the same. Is there a way for me to “junk it” based on subject?
Answer: There is a lot you can do with Rules. For example, you can right click on the annoying message and select Rules > Create Rule. From here you can list the subject (or part of the subject text) and check Move item to Folder “Deleted Items” or “Junk” or even create a new folder so that you can check that folder anytime. This is a nice way to route mail out of your inbox and then the folder name will be bolded when something new is in that folder. But you need to be diligent about checking those folders for new mail. Keep in mind, however, if you get a legitimate message with the same subject text, it will also be routed to that folder, which is why you may want to check that folder occasionally and not necessarily send to the deleted items folder.
You can create more complex rules based on conditions, exceptions, etc. Get to those options by clicking on Advanced Options. More information about Rules are here.
Spammers are clever, however, and sometimes it is hard to get rid of some of that junk mail because they change their address or subject lines.
