Problems with accessing my dlc content

Hi guys, do any of you know how to access loot boosters dlc packages etc from the £99 edition for borderlands 3? I can’t check my mail and I can’t find anything to do with it, all I have are the trinkets on my guns, I can’t even use a mod yet and I’m level 13.

Pls help

Can’t check your mail? All dlc contents are in your (menu->social->mail); assuming you have it. Also check your rewards history to ensure you didn’t accidentally pick it up already.
