1. Serve customers
Customer service begins the verified post office workflow. Follow the current task shown by the game and complete that part before moving your attention to package handling.
2. Carry and sort packages
Package sorting connects customer service with dispatch. Official media shows packages being carried with exterior name labels and shows sorting shelves, but it does not establish the exact matching rule. Use the current in-game directions.
3. Load packages onto the boat
Loading packages onto the boat completes the verified work chain. Treat it as part of the same loop rather than a separate side activity.
4. Earn Coins and repeat
The official description says this work earns Coins. Coins unlock stands and characters, but it does not provide the effects, prices, or a required order for those unlocks.
Recommended team setup—not a game rule
Mail Simulator supports solo play and cooperation with up to five friends. In a group, you can try assigning customer service, sorting, and boat loading to different people so everyone knows what they are watching.
That division is a recommended team setup only. No fixed-role requirement is verified, so change the setup whenever the live task makes another approach clearer.
