feature request: mail filter suggestions

This is for all email clients on all platforms.

I keep running into people who moan about how much email they get and how they so far behind blah blah blah . . . . .

Do these people not understand what mail filters are for or how they work? I have to wonder if they understand the basics of filing paper documents: the principles are the same. What I have done for years is take my most frequent correspondents and filtered their email in their own mailbox, so a. I don’t miss any of their mail, and b. to unclutter my inbox. The stuff that doesn’t fall under any rubric stays in the inbox and can be dealt with as I get to it. But stuff from the people who I correspond with frequently gets filtered out so I can be sure I get to it.

Is this so hard? The people who tell me they have 700 or 1000 unread emails probably need it all printed out for them: perhaps they would find it easier to deal with.

So my feature request would be for an email client to review the corpus of already received email against new email and offer to create a filter based on the receiver’s particulars. Apparently some folks need the help with this . . . . .
