Cat Mail Co. Updates

Cat Mail Co. launch — July 9, 2026

Cat Mail Co. launched on Steam July 9, 2026 from Maracas Studio with publisher support from Gamersky Games. Launch week included a free Supporter Pack for early buyers — soundtrack, wallpapers, and artbook content tied to the Steam store page.

Steam user reviews landed Very Positive in the first days. Players praised the cozy loop: weigh, stamp, sort, customer bell, boat manifest, moonlight reveals.

This Cat Mail Co. updates page tracks patch notes as Maracas Studio ships balance and quality fixes. Bookmark guides for mechanic pages that update alongside patches.

The game ships as a premium Steam title — no free-to-play economy, battle pass, or in-game cash shop alongside the postal sim loop.

Demo and save transfer

A free Cat Mail Co. demo is on Steam with save transfer to the full game. Demo progress carrying forward lets you learn scale bands, F-key stamp mode, and Port Windy unlock before purchase.

Demo saves may lag behind full-game unlocks if the demo build caps destinations — verify on the store page before assuming full Cat Island map parity.

Platform availability

Cat Mail Co. is Windows PC on Steam at launch. Store pages for Switch, PlayStation, or Xbox are not listed — this wiki focuses on the Steam build only.

Online co-op supports up to four Steam players in the same office instance. Cross-platform play is not applicable on a single-platform launch.

No codes or redemption system

Cat Mail Co. is a premium Steam sim — there is no Roblox-style codes list, no daily redemption box, and no promo string menu in the post office.

Progress unlocks through backlog clearing, boat routes, rooms, and tools. Ignore third-party "codes" sites; they target keyword spam, not this game.

Wiki policy: we do not publish a /codes page. Updates here will never include fake redemption strings.

Post-launch expectations

Maracas Studio has not published a long public roadmap at launch. Watch the Steam news hub and this page for patch titles and mechanic notes.

Likely update targets based on community feedback: controller support, achievement name documentation, and quality-of-life shelf tools.

Mechanic pages (package handling, night mechanics, destinations) receive wiki edits when patches change verified behavior.

July 2026 launch window means rapid hotfixes are possible — re-read controls after patches if bindings change.

Launch week notes

Cat Mail Co. shipped July 9, 2026 on Steam with day-one online co-op for four players, 17 achievements, and the moonlight night cycle described on the store page.

Early buyer Supporter Pack bundled OST and wallpapers — cosmetic to the wiki, but proof of active Maracas Studio post-launch presence.

Demo players transferring saves should verify Port Windy unlock parity — demo caps may differ from full game map.

Wiki pages verified against launch-week builds; report drift on community when patches land.

How this wiki tracks patches

We update Cat Mail Co. guides when verified mechanics change — scale bands, scanner behavior, new destinations, achievement counts.

Patch notes without in-game verification get a "pending" label until a player confirms behavior on Steam build.

No codes will ever appear in updates — Maracas Studio progress is save-based, not redemption-based.
