Allow users to create a filter rule that holds incoming emails from specific senders and only delivers them to the inbox at a user-defined time (e.g., a fixed hour each day, or specific days of the week), instead of showing them immediately upon arrival. This would let users control when certain types of emails — such as newsletters, notifications, or work messages from specific contacts — appear, reducing interruptions while still ensuring nothing gets lost, unlike simply archiving or labeling messages out of sight indefinitely.
