Hey folks, welcome to the mailroom! If you’re diving into Cat Mail Company like I did, that first pile of unsorted packages can feel overwhelming.
Don’t sweat it, I’ve played through the tutorial and early days, and here’s your real guide to turning that messy post office into a well-oiled (and adorable) delivery machine so your package return rate drops the most.
What You’ll Read:
Getting Started & Core Loop
This is simple but might be helpful in the early game: Use WASD to move, Space to jump, Shift to sprint. Right-click to rotate parcels so names face you. Tab for quick placement.
The core loop? Handle counter customers (deliver Cat Island pickup parcels by matching descriptions), process outgoing parcels (scan, weigh, stamp, inspect), organize storage, then load the boat for the captain’s current routes at dawn and dusk. Time advances mainly with happy customers so take your time and focus on accuracy.
Key Challenges & Smart Solutions
Just like Arcane Library or Supermarket Chaos, this game is all about managing some items. Here we call these items parcels (packages). They are unsorted and massive, need stamps, sometimes heavy and fragile and should be delivered to the boat.
While it can feel overwhelming at first, games like this are designed to be relaxing once you get the hang of it.
The Massive Unsorted Pile
This is everyone’s biggest headache early on.
Fix: Sort by destination first (Cat’s Island stays local, others go to Port Windy or Sunny Shores). Use shelves/cubbies for small boxes and floor space for big or tall ones. Keep names visible. The pile shrinks as you progress and unlock rooms.
Scanning, Weight & Stamps
I guess that new players often mess up the number of stamps or constraints. Just like myself when I first started the game.
Fix: Always scan customer parcels to prevent mistakes. Match destination + weight (check the board: blue = 4 stamps, yellow = 2, green = 1, etc.). If a parcel is fragile put nothing on its top. If it’s heavy, put nothing underneath. Packages will be damaged if you don’t do so.
Tip: Always scan incoming boat parcels too. They may have hidden traits. Match the weight board exactly (numbers of stamps). Use the red placement indicator as your guide for stacking violations.
Boat Loading & Captain Runs
Overloading or wrong destinations lead to returns and damage.
Fix: Stage Port Windy parcels near the dock and load heavy items at the bottom. Ring the bell when ready. The more you ship correctly, the faster you fill the progress bar and unlock new rooms.
Lover Parcels
Lover parcels must ship together as a pair. Identify them at night using the Revealuna. Revealuna is a moonlight tool you unlock as you progress. It reveals hidden properties and a wispy light can lead you to the matching parcel.
Mark both (often with heart stamps) and send them on the same boat run. They can have differing storage needs.
Why Parcels Get Returned
Returning Parcels is not completely bad. When they come back, they usually have a note on them or an obvious damage, after a while this help you learn the patterns.
Anyway you want to prevent it, so I’ll help. From what I and other players have experienced, returns usually happen for one of these reasons:
Wrong Destination
The captain only takes parcels for his route. Although sometimes he has multiple destinations. Anyway if you load the boat with the packages of other destinations, they will return.
So always double-check the stamp or label before loading. Keep separate staging areas, one shelf for local Cat’s Island stuff, another clearly marked for the captain’s route.
Here’s another useful tip: As soon as you see the captain, separate everything going out. This prevents mixing up local vs. outgoing.
Cold Storage Parcels on the Boat
Yes, this is a big one! Cold packages must stay in the Cold Room until the last possible moment. You should know that the dock itself is an uncooled zone, so a cold parcel left sitting there during the day will take sun damage even if you never technically shipped it wrong.
My safe routine: keep cold parcels in the Cold Room through the whole day phase. Once the captain has arrived and you’ve served your last customer, make one final trip to grab your outgoing cold parcels and load them right before you ring the departure bell (not any earlier). Standard (non-cold) parcels are actually fine to store in the Cold Room overnight with no penalty, so when in doubt, the freezer is the safer default.
Fragile or Heavy Violations
Fragile packages with stuff stacked on top, or heavy ones crushing things underneath, get damaged during the trip.
Load heavy at the bottom, fragile on top with nothing above them. The red indicator when placing usually warns you.
Tip: You can put a fragile package on top of another fragile package. Just use the red indicator as final judge and take it serious.
Missing or Wrong Stamps
Always weigh and stamp after scanning. The weight board tells you exactly how many are needed. Use the correct destination stamp every time. If you do it wrong, parcels will return.
