Patterns for list broker spam?

Every day I get a bunch of spam from fake list brokers, invariably from throwaway Gmail or Outlook
accounts.

The text in them seems fairly consistent.  Anyone have patterns to catch them?  They're quite annoying
since they're hard to separate from the legit mail we get from giant mail systems.

TIA

PS: One time I got spam offering a 3000 name list of attendees from a recent IETF meeting which was
pretty impressive since only 1000 people were there.
