No, the real standard in use decades before the masses fucked up the internet is to use a capable mailer and capable filters and conform yourself to the awesome. If you're getting too much mail, turn it into not much mail with neomutt, maildrop, msmtp, fetchmail, etc. Users can also fuck around with Thunderbird or Mailpile. If you're using gmail webinterface, good luck, it's garbage.
Stuffing bloated redundant meta crap in the subject line isn't going to happen.
