Cat Mail Co. Stamps Guide

Cat Mail Co. stamps wiki

Cat Mail Co. stamps are the postage and sticker tools that make Cat Island mail legal to ship. Every parcel you process in Cat Mail Co. needs enough postage for its scale band, the correct destination stamp for the captain's route, and any hazard stickers the scanner reveals — fragile, heavy, cold, hot, or lovers heart.

This Cat Mail Co. stamps guide covers postage counts from the scale color bands, destination stamps such as Port Windy, hazard stickers from the scanner conveyor, the heart stamp for lovers parcels, decorative flair stamps, and common failures that send mail back damaged.

Stamps in Cat Mail Co. are not redeem codes and not a gacha currency. You apply them in stamp mode on the parcel surface until the game accepts the postage and route. Progress still comes from clearing backlog and unlocking rooms — stamps only validate each box.

If you are brand new, skim the beginner guide for the first-day loop, then return here when wrong stamps start causing returns. Deep pipeline detail (weigh → label → stamp → shelf) lives on the package handling guide.

Postage stamps and scale color bands

Postage Cat Mail Co. stamps answer one question: how many functional stamps does this parcel need for its weight? Place the box on the scale and read the dial against the color bands before you decorate anything.

Launch-week builds of Cat Mail Co. teach postage with clear band colors. Community-verified counts map roughly as: green → 1 stamp, yellow → 2 stamps, blue → 4 stamps, purple / max → 6 stamps. Treat the on-screen band legend as the source of truth if a patch renumbers exact tiers.

In stamp mode, place functional postage stamps until the parcel meets the band. You do not need a perfect grid — overlapping stamps still count as long as the total registers. Wrong destination stamps still fail even when postage count is perfect.

Cat Mail Co. stamps for postage are separate from decorative art. A box covered in flowers with zero postage stamps is still illegal cargo. Finish the weight requirement, then optionally adorn.

• Do01Weigh the parcel on the Cat Mail Co. scale before stamp mode
• Do02Read the color band — do not guess stamp count by eye
• Do03Open stamp mode with F and apply postage until the band is satisfied
• Do04Confirm destination stamp matches the map route before shelving

Destination stamps and map routes

Destination Cat Mail Co. stamps tell the boat which island or route owns the parcel. Early saves focus on Cat Island locals and the unlocked Port Windy expansion. Stamp icons line up with the wall map — for example, Port Windy often uses a lighthouse-style destination stamp in tutorial flows.

Always cross-check the captain's manifest and the map before you autopilot yesterday's stamp. Reusing a Port Windy stamp on Cat Island pickup mail — or the reverse — is one of the fastest ways to create damaged returns in Cat Mail Co..

Destination stamps stack on the same surface as postage. On small boxes with a 4- or 6-stamp requirement, overlap postage stamps first so there is still room for the destination mark. Stamp overlapping is allowed; missing the destination mark is not.

As more routes unlock, treat destination stamps as a growing rack of island IDs. Shelf organization by destination (see organization tips) keeps the right stamp within reach of the right pile.

Hazard stickers from the scanner

Hazard stickers are special Cat Mail Co. stamps (often shown as stickers in the stamp/sticker menu) that mark handling constraints the naked eye can miss. Run customer parcels and mystery boxes through the scanner conveyor; when the X-ray shows a symbol, apply the matching stamp before you shelf or boat-load.

Fragile: glass-style icon → fragile stamp. Nothing may sit on top of a fragile parcel on shelves or in the boat.

Heavy: weight icon → heavy stamp. Heavy parcels crush anything stacked underneath — keep them at the bottom of piles.

Cold / hot: after you unlock refrigerated or heated rooms, snowflake or heat icons require temperature stickers and correct room storage. Skipping them creates spoiled or returned freight later in Cat Mail Co. progression.

Scanner stamps are mandatory when the machine flags a constraint. Decorating a fragile box without the fragile stamp still fails validation if the ship expects the hazard mark.

Heart stamp and lovers parcels

Search interest for cat mail co heart stamp and cat mail co heart packages maps to lovers parcels in Cat Mail Co.. After lovers mail unlocks, the scanner can show a love-heart cue — apply the heart stamp so the parcel is correctly identified.

The heart stamp is a functional identity mark for lovers packages, not the same as a decorative flower or optional cute sticker. Decorative hearts may exist in the flair tab, but only the lovers/heart response that matches the scanner unlocks the related Steam achievement and correct handling.

Lovers parcels often interact with night and story beats — moonlight and paired mail rules still apply. After you heart-stamp, shelve carefully and read night mechanics if paired moonlight parcels appear on the same shift.

If GSC or Google sent you here for "cat mail co heart," start with the scanner: no heart icon means you do not need the lovers stamp yet. Early decorative stamps will not unlock lovers content early.

• Do01Unlock lovers packages through normal Cat Mail Co. progress
• Do02Scan the parcel and confirm a love-heart cue
• Do03Apply the heart stamp from the functional sticker set
• Do04Do not confuse decorative flair hearts with the lovers mark

Decorative stamps and flair

Decorative Cat Mail Co. stamps are optional art — band-aids, flowers, tiny illustrations — that raise parcel charm without changing postage math. Apply them after functional postage, destination, and hazard stamps are complete.

Steam achievements reward decorative play: placing your first decorative stamp, stacking ten stamps on one parcel (postage + decor combined), and lifelong totals such as five hundred stamps across a save. See achievements for verified names and tips.

Co-op crews often assign one player to stamp mode aesthetics while another owns scale bands. Fun is intentional in Cat Mail Co., but never let decoration slow the dock bell when the captain's manifest is waiting.

Decorative stamps do not fix wrong destinations, under-postage, or missing fragile marks. Treat them as celebration after the legal stack is correct.

Recommended stamp workflow

Use this order every time you handle a parcel that needs Cat Mail Co. stamps:

1) Unload or accept the parcel. 2) Weigh on the scale and note the color band. 3) Confirm destination from map / customer / captain. 4) Scanner if the box is from a customer or looks ambiguous. 5) F stamp mode: postage count → destination stamp → hazard stickers (including heart) → optional decorative stamps. 6) Shelf by destination zone. 7) Load boat with fragile on top, heavy low.

Pre-stamping outgoing stacks before the captain speaks is a mid-game skill from advanced play — weigh and stamp ahead, then only re-check when the manifest names a route. That keeps Cat Mail Co. stamps work from bottlenecking dusk departures.

Common stamp mistakes

Guessing stamp count without the scale is the classic Cat Mail Co. stamps error — color bands exist so you never eye-ball postage.

Autopiloting yesterday's destination stamp after unlocking Port Windy mixes local and export mail. Keep destination stamps next to destination shelves.

Skipping the scanner leaves fragile and heavy parcels unmarked even if you stacked carefully by habit — later you forget and crush a box.

Confusing decorative hearts with the lovers heart stamp leaves lovers packages unidentified.

Opening stamp mode without a clear surface plan on six-stamp purple parcels wastes time overlapping randomly; place postage density first, destination last in the free corner.

Stamp-related Steam achievements

Several Steam achievements in Cat Mail Co. are stamp-native: first decorative stamp, correctly identifying fragile / heavy / cold / hot / lovers (heart) parcels, stacking ten stamps on one package, and large lifetime stamp totals.

Hunters should keep stamp mode practiced even on quiet days — decorative achievement progress is free while you wait for dusk boats. Pair this page with the full achievements table for names such as Until Shipment Do Us Part (lovers / heart) and Heavy Duty (lifetime stamps).

There are no codes that grant stamps. Any third-party "free stamps code" list is unrelated spam — Cat Mail Co. stamps come from the office toolkit, not redemption menus.
