Same. Basically everything that comes from a legitimate mailing list/subscription has it. Even stuff I would personally consider spam like political mailing lists have it.
It’s only the worst spam stuff that doesn’t. The obvious scam stuff sent to any email address they can find, containing every language I don’t speak, with lots of bad obfuscation to stop keyword scanners from 2002.

There's the fly in the ointment. "Legitimate" shades off very slowly into bottom feeding Sanford Wallace-ass spamming. The temptation to become worse and worse is real, economics favor spamming, as it externalizes advertising costs. Until the torches and pitchforks come out.
