If parcels are invalid or coming back, read the Boat Destinations guide. If special package traits are confusing, read the Package Types & Rooms guide.

Cat Mail Co. is a cozy post office sorting game about matching customer pickup clues, stamping outgoing parcels, loading the right boat routes, and handling special package traits as the post office expands. The difficulty is not just stacking boxes; it is keeping every parcel on the right route while new rooms, night checks, and backlog pressure appear.
Start here. Pick the guide based on the system you are trying to understand.
| Read order | If you are working on… | Read this guide | Why |
|---|---|---|---|
| 1 | First shifts, pickup clues, stamps, scanner, night work | Beginner Guide | Builds the first working post office route |
| 2 | Invalid parcels, returned parcels, wrong boat, captain heading | Boat Destinations & Invalid Parcels | Fixes route mistakes before the dock bell |
| 3 | Heavy, fragile, cold, hot, damaged, lovers, rooms | Package Types & Rooms Guide | Explains how package traits change the route |
| 4 | All 17 achievements, Float Mail Co., Heavy duty, All cleaned up | Achievements Guide | Gives a 100% route order instead of menu-order chasing |
The detailed guides cover each system, but this short route is enough to understand how the game thinks.
| Route layer | What it means | Go deeper |
|---|---|---|
| Cat Island pickup | Customers request parcels by name, last name, shape, ribbon, size, or clue | Beginner Guide |
| Outgoing parcel | Parcels for Port Windy, Sunny Shores, Crescent Bay, or later routes need destination handling | Beginner Guide |
| Destination stamp | Shows where the parcel is supposed to go | Beginner Guide |
| Weight stamps | Match the scale result to the weight board count | Beginner Guide |
| Scanner / hidden traits | Heavy, fragile, cold, damaged, hot, lovers, dark, or light conditions may change handling | Package Types & Rooms Guide |
| Destination staging | Prepared outgoing parcels should sit in readable route piles | Boat Destinations & Invalid Parcels |
| Captain heading | The boat only takes destinations the captain names today | Boat Destinations & Invalid Parcels |
| Achievements | Most achievements are easier after the route is stable | Achievements Guide |
Use this table if you know the symptom but not the cause.
| Problem | Most likely cause | Best next guide |
|---|---|---|
| A customer keeps rejecting the parcel | Pickup clue was matched too loosely | Beginner Guide |
| You cannot tell pickup parcels from outgoing parcels | Cat Island counter mail and destination mail are mixed | Beginner Guide |
| Destination or weight stamps are confusing | The parcel is prepared in the wrong order or the board is being misread | Beginner Guide |
| A parcel came back even though it had stamps | It was prepared but not sendable on that captain route | Boat Destinations & Invalid Parcels |
| The boat warns about a wrong parcel | A destination not named by the captain is on the boat | Boat Destinations & Invalid Parcels |
| The boat will not accept a box | Stack height, bad angle, or awkward placement | Boat Destinations & Invalid Parcels |
| Heavy or fragile parcels keep causing mistakes | Placement rules are being treated like normal sorting | Package Types & Rooms Guide |
| Cold parcels are forgotten | Cold storage is not part of the route check | Package Types & Rooms Guide |
| Damaged parcels are confusing | Repair / re-check route is not separated from normal mail | Package Types & Rooms Guide |
| Lovers parcels are hard to identify | Relationship clues are being treated as flavor text | Package Types & Rooms Guide |
| You want Float Mail Co. or Heavy duty | Achievement timing matters more than rushing | Achievements Guide |
| You want All cleaned up | The pile needs routing cleanup, not dumping | Achievements Guide |
These are the ideas that connect the whole Cat Mail Co cluster.
| Rule | Meaning |
|---|---|
| Route before size | Do not sort only by box shape. Decide pickup, outgoing, destination, and room route first |
| Prepared before boat-ready | A stamped parcel still waits if the captain is not going there |
| Trait before shipping | Heavy, fragile, cold, hot, damaged, lovers, dark, and light parcels may need extra handling before normal routing |
| Returns stay visible | A returned parcel should not disappear back into fresh mail |
| Achievements wait for stability | 100% cleanup is easier after routing, rooms, and boat loading are under control |
Sort by route before size. Check destination before weight. Check the captain before the boat.
If you remember only one thing from this hub, make it this: Cat Island pickup parcels, outgoing destination parcels, special package traits, rooms, returns, and achievements all become easier once every parcel has a clear next stop.
Start with the Beginner Guide if you are still learning pickup clues, outgoing parcels, destination stamps, weight stamps, scanner checks, night work, and the first boat routes.
Use the Boat Destinations & Invalid Parcels guide if parcels are coming back, the boat rejects boxes, the captain route is confusing, or you are getting wrong parcel warnings.
Use the Package Types & Rooms guide for heavy, fragile, cold, hot, damaged, lovers, dark, light, repair workshop, cold storage, heated room, and multi-trait parcels.
Use the Achievements Guide for all 17 achievements, 100% route order, missable notes, Float Mail Co., Heavy duty, All cleaned up, room achievements, manual extras, and story completion.
Sort by route before size. Pickup parcels need visible clues near the counter, while outgoing parcels need stamps, checks, destination staging, and the correct captain route before the boat.
No. A stamped parcel may be prepared, but it is only sendable today if the captain is going to that destination and its trait, room, damage, and placement checks are handled.
