Because of changes to Gmail’s inbox, updates from the Zoo may go in the Promotions or Updates tab of your inbox instead of the main Primary tab. Please take a moment to be sure that you’ll see messages from us.
Move a message from us into your Primary tab by doing the following:
1) Look through your messages in the Updates and Promotions tabs to find a message from the sender Philadelphia Zoo
2) Click once on the message and drag it up to the Primary tab on the left.
3) Click “Yes” to automatically have messages from us go to the Primary tab.
