Labels/Tags are a product feature, not part of email standards. Meaning: it’s not a thing when looking at the raw mail server data.
Thanks for the info. This helps me understand why things are the way that they are. It has me rethinking the use of tags altogether and leaning more toward reviewing my labels in gmail so I can tweak the ones that are still useful and remove any that are obsolete.

yo dawg, I heard you like AI 😆
