About this extension
Streamline Your Shipping Workflow
Postal Manager by Factory Engine turns your browser into a dedicated shipping workstation. Designed for high-volume shippers, small businesses, and e-commerce sellers, it allows you to print perfectly formatted envelopes, generate USPS Intelligent Mail Barcodes (IMb), and track your packages without ever leaving your browser or paying monthly subscription fees.

Core Features (Always Free):

Smart Envelope Presets: Save custom dimensions and margin layouts for any physical envelope size (Standard #10, A2, 6x9 Booklets, etc.).

One-Click Pasting: Instantly grab address blocks directly from your operating system's clipboard.

Dynamic Barcode Generation: Generate strict, USPS-compliant Intelligent Mail Barcodes using your Mailer ID (MID).

Domestic & International Modes: Automatically adjust physical layouts, endorsements, and mail class text based on the destination.


Factory Engine Pro Features (One-Time Upgrade):

Local Shipping Database: Automatically log every printed label, recipient, and tracking number into your secure browser vault.

Universal Carrier Tracking: Track packages across the USPS, FedEx, UPS, and international networks using the live tracking drawer.

Auto-Serialization: Automatically increment your USPS barcode serial numbers to prevent duplicates.

CSV Export: Export your entire shipping history to a spreadsheet for accounting and record-keeping in one click.


Privacy by Design
Your data belongs to you. Postal Manager processes all barcode mathematics and layouts entirely on your local machine. Your shipping log and address histories are saved strictly to your browser's local, secure vault and are never transmitted to third-party marketing servers.
