If you have any rewards waiting for you in Borderlands 3, you will need to check your mail. As that’s where rewards will be sent to for you to collect.
This includes any pre-order content, VIP content, deluxe content and golden keys. You will also receive milestone rewards in your mailbox, such as weapons for killing X amount of enemies etc.
Below, we’ve put together a short guide showing just how to access the mailbox in Borderlands 3. For more Borderlands 3 Guides & Best-of content for PS4, PC and Xbox One, make sure to check out our dedicated area here!
Checking for Mail
First, we need to head to the main menu. You can do this on PC by pressing ESC (or start on a controller). From there, choose the ‘Social option’.

In the Social area, you can invite friends, kick players, redeem rewards via SHiFT Codes and check your mail. Using the tabs in the top left, head to the 4th one along which is labelled as ‘Mail’.

Inside your mail, you can see any items that you need to redeem. You will need to actually accept them, by pressing E on PC. Then they will go into your inventory where they can be equipped/used. Some players are reporting that some pre-order content doesn’t arrive until around level 8-10.
