I file my mail meticulously. The only things I want in my inbox is stuff I need on hand quick (like a boarding pass) or stuff that still needs immediate action. Everything else I try to file in a myriad of folders spread over various IMAP accounts and even some local folders. On macOS Mail I usually just end up dragging emails to one of the folders in my always displayed folder list (left pane). On iOS Mail I usually hit the folder icon at the bottom. Two things can then happen (and I’m not clear as to why one or the other happens): I’m displayed a list of folders to chose from, or I am presented a box with two options: a specific folder to move it to and “Other Mailbox…”.
It’s that specific folder I can’t figure out. Sometimes it’s an excellent suggestion, but other times it’s terribly off. But I cannot figure out what the logic behind this suggestion is. Is it sender, is it subject, is it related to email content? So far, every time I thought I had figured it out I eventually get shown a suggestion that appears to defy the logic I thought applied.
Does anybody understand how this really works?
