Cozy Post Office Sim Cat Mail Co. Hits 95% on Steam Ahead of July 6 Launch

Cozy Post Office Sim Cat Mail Co. is set for a July 6, 2026 Steam launch after strong showings at Steam Next Fest June 2026. The Belgian indie debut from Maracas Studio earned a 95% positive rating from 185 players during the event, which ran through June 22 and featured more than 4,200 free demos—the largest edition in Next Fest’s six-year history. Cat Mail Co. tasks players with restoring a chaotic post office on Cat’s Island after the previous postmaster disappears. Each in-game day starts when mail arrives by boat, and players sort, weigh, apply postage, flag fragile or heavy parcels, and load outgoing deliveries without timers or precision penalties. A day/night cycle also changes parcel handling, tying into the mystery narrative. Online co-op supports up to four players.
