Create: Envelope Compat makes Create packages and Envelope packages **the same thing**. No more choosing between automation-friendly Create crates and Envelope's mail system - you get both, seamlessly.

This works two ways: - **Pre-addressed packages** arriving at the packager are intercepted and routed to the mailbox whole - **Freshly packed packages** (items in → crate out) are transferred to the mailbox before the frogport above can snatch them This means your Create packing setup feeds directly into Envelope's mail delivery without any intermediate chests, hoppers, or redstone contraptions. ### Pigeon Delivery & Lost Mail Return Once a package lands in SLOT_MAIL, a pigeon picks it up and delivers it to the recipient's mailbox. If delivery fails (wrong address, no recipient), the package is returned to the **sender's mailbox inbox** as lost mail.

The complete loop: *Packager → Mailbox → Pigeon → Recipient / Lost Mail Return → Funnel → Back to Packager* ### Factory Gauge Restock The factory gauge can see **inside the package sitting in SLOT_MAIL** using virtual item handler slots. When it detects that the gauge's promised item is inside the crate, the promise is completed. This means your Create restock system works perfectly with mail-sent packages - no special configuration needed. ### Mechanical Arm Support Right-click a mailbox while holding a mechanical arm to link it. The arm can: - **Deposit items** into SLOT_MAIL (ready for pigeon dispatch) - **Extract items** from the inbox (received mail, returned packages) No GUI opens when linking the arm connects directly, just like it does with basins, depots, and packagers. ### Payback Tag Compatibility Payback tags work on Create packages through two paths: - **Crafting table**: Combine a payback tag with a Create package in the crafting grid - **Shift-click**: Right-click a Create package with a payback tag in hand Payback Packages (the ones the mail service sends as payment) are **never converted** to Create format - they keep their identity so the pigeon system recognizes them correctly. --- ## Requirements - **Create** - *because obviously* - **Envelope** - *the mail system this mod extends* --- <div align="center"> </div>

## Video Demonstrations

## ✨ Features

### Full Package Interop - Create packages carry Envelope addresses natively - a package packed by a Create repackager can be sent via pigeon - Envelope packages are automatically converted to Create packages when extracted from mailboxes (GUI, funnel, hopper, mechanical arm) - Addresses sync both ways: slap an Address Tag on a Create package and it gets routed right alongside Envelope mail

### Packager → Mailbox Pipeline The packager never unpacks addressed packages - instead it places them directly into the facing mailbox's SLOT_MAIL, ready for pigeon pickup. This works two ways:

  • Pre-addressed packages arriving at the packager are intercepted and routed to the mailbox whole
  • Freshly packed packages (items in → crate out) are transferred to the mailbox before the frogport above can snatch them

This means your Create packing setup feeds directly into Envelope's mail delivery without any intermediate chests, hoppers, or redstone contraptions.

### Pigeon Delivery & Lost Mail Return Once a package lands in SLOT_MAIL, a pigeon picks it up and delivers it to the recipient's mailbox. If delivery fails (wrong address, no recipient), the package is returned to the sender's mailbox inbox as lost mail. From there, a funnel or mechanical arm can extract it and feed it back into your Create sorting system.

The complete loop: Packager → Mailbox → Pigeon → Recipient / Lost Mail Return → Funnel → Back to Packager

### Factory Gauge Restock The factory gauge can see inside the package sitting in SLOT_MAIL using virtual item handler slots. When it detects that the gauge's promised item is inside the crate, the promise is completed. This means your Create restock system works perfectly with mail-sent packages - no special configuration needed.

### Mechanical Arm Support Right-click a mailbox while holding a mechanical arm to link it. The arm can: - Deposit items into SLOT_MAIL (ready for pigeon dispatch) - Extract items from the inbox (received mail, returned packages)

No GUI opens when linking the arm connects directly, just like it does with basins, depots, and packagers.

### Payback Tag Compatibility Payback tags work on Create packages through two paths:

  • Crafting table: Combine a payback tag with a Create package in the crafting grid
  • Shift-click: Right-click a Create package with a payback tag in hand

Payback Packages (the ones the mail service sends as payment) are never converted to Create format - they keep their identity so the pigeon system recognizes them correctly.

## Requirements

  • Create - because obviously
