You've got mail
by The_Plague
You've got mail adds a postal system to the world, where players send letters through envelopes, postboxes and mailmen between one another.
What it does
The project builds its mail system around players acting as mailmen. A player can become a mailman in the world and deliver messages between other players, and the mod adds envelopes that each hold one stack of items. Letters are placed into item postboxes to be sent off, and a receiving player collects letters from the postbox that was used for them.
Writing a letter uses the Envelope item. Holding an empty envelope in the main hand and right-clicking with an item in the off hand opens a GUI that asks for the addressee and a text. Once closed, the envelope shows its information in a tooltip, and a right-click takes the item out of the closed envelope. A second click returns both the opened envelope and its item.
The mod is for NeoForge only, with files covering 1.21.1 – 1.21.11 across eleven game versions. Client and server means the server and every player need it. It is released under the Apache License 2.0 and is not open source. The latest file is 1.1 for 1.21.11, published as an alpha build on 2026-07-30.
Key features
Player-run mail delivery

Envelopes holding items

Postboxes for sending and receiving
Item postboxes are where letters are put to be sent off and where letters addressed to a player arrive.
Addressed letters
An input screen asks for the addressee and the message text, and the closed envelope shows its details in a tooltip.
