No, because I can search my emails for sender, recipient, words in the subject/body, etc. When I get an email that I think I may need to find later but it doesn’t include relevant keywords (for example, the project or client name) I forward it to myself with the keywords added. I haven’t used email folders for a decade, I rely on searching. I use GMail. Sometimes email messages have information that belongs somewhere else, like a bug report or a task. I transfer those to the relevant system or document when I receive them.
