What’s the difference between “temporal inboxing” and “persistent inboxing”?

Temporal inboxing: Placement fluctuates based on recent signals:

Recent engagement, content, and behavior heavily influence each placement decision. Placement can shift quickly with changing conditions.

Persistent inboxing: Placement remains stable over time:

Established reputation creates consistent treatment. Small variations do not significantly affect placement.

New senders experience more temporal variation. Established senders with strong reputation enjoy more persistent treatment.

Build toward persistent positive placement through consistent good behavior.

New ships face inspection each voyage. Trusted merchants sail through with established credentials.
