The My Mailman was a Zombie Lost & Found Quest in Dead Island 2 can be started during The Final Gauntlet story quest after you’ve unlocked fast travel. When you’re ready to begin, travel to Alpine Drive in Bel-Air just east of Curtis’ house.
There you’ll find the Signature Required journal on the ground next to a black delivery van.
For this quest, you’ll need to follow the mailman’s paper trail to an awesome new weapon! If you read the Signature Required journal, you’ll find the addresses of where the deliveryman was going. The first is Colt’s house then the GOAT Pen and lastly 143 Glitterati Corner. Make your way to all 3 houses (in any order) and inspect the stack of packages as shown in the images below.
Colt’s House
Goat Pen
Glitterati Corner
After going to all, Wayne the Mailman will spawn.
Defeat him and grab the key he drops. Return to the delivery van and loot the crate next to it to receive Raven (a rare sharpshooter gun). For more guides on Dead Island 2, click here!
