Invisible Transition in Email Spam Filtering

The primary inbox displays all incoming emails as they arrive. Messages from contacts, newsletters, and other sources appear in the list for review.

Daily use proceeds with emails landing in the inbox, notifications sounding, and interactions like reading and replying occurring seamlessly. The interface remains consistent, showing the familiar flow of correspondence.

Standard email inbox filled with recent messages

A message expected from a regular sender does not show in the inbox. It appears instead in the spam folder.

The inbox now contains only emails not directed to spam. Messages once visible there route directly elsewhere, changing what populates the primary view.

This arrangement persists without signals of the shift from the prior state, where all emails entered the inbox upfront.
