Physical Mailboxes
Players can use in-world mailbox structures to access their mail. A physical mailbox is built with a fence post, a single chest or barrel on top, and a sign attached to the front face of the container.
Minecraft Mailbox Plugin for Spigot, Paper, and Purpur
MailboxGUI
MailboxGUI 5.2.0 brings a redesigned, filterable inbox to Spigot, Paper, and Purpur servers, alongside physical mailboxes, letters, packages, COD, money mail, optional expiration, route-aware sending, a Shared Admin Inbox, and validated storage conversion. Redis and multi-backend network mode are available in MailboxGUI Premium.
Features
Core tools for server mail, delivery, economy, and administration.
Letters
Send paper or signed Book Letters, with route-aware player, admin, command, and API sending that follows the server configuration and permissions.
Packages
Send item deliveries through MailboxGUI using configurable package slots. Packages can hold normal items and, when enabled, package experience.
COD Packages
Cash-On-Demand packages let the recipient preview a delivery and pay before accepting it, making player shops, trades, and marketplace-style delivery easier to manage.
Money Mail
Send economy currency through the mailbox inbox system when Vault and a compatible economy plugin are enabled.
Post Offices
Create public Post Office boxes that let players access their own mailbox menu from shared server locations like towns, spawn, markets, banks, or mail rooms.
NPC Support
Use Citizens NPCs as Post Office access points so players can open their own mailbox menu through marked server NPCs.
Admin Tools
Staff can send expiring server mail, inspect inboxes, manage registered mailboxes and Post Offices, and use confirmed purge and cleanup workflows.
Storage Support
Use YAML, SQLite, or MySQL storage with validated conversion, source and target backups, and safer upgrade handling.
Shared Admin Inbox
Route configured COD payments and declined or expired returns to a shared, filterable staff inbox.
Inbox and Expiration
The redesigned inbox adds session filters for date, new mail, type, expiration, and admin mail, while optional expiration removes stale deliveries safely.
Multi-version Support
Spigot, Paper, and Purpur compatible for local and single-server setups. Network mode is separated into MailboxGUI Premium.
