What is a Lookup Item?
If people send you with an incomplete address, we look up such and match such items manually to your account. This causes the disruption in our automated process and thus the delay of their entry into your Inbox. You can view which items are lookup items by the red bookmark icon to the left of the image.
What to do with a Lookup Item?
We recommend customers contact these senders and ensure the correct, complete address next time.
