1. Sorting
Sorting means classifying mail and parcels by destination, urgency, recipient, or route so distribution happens quickly and precisely.
Why It's Important
Accurate sorting slashes delivery errors, speeds distribution, and keeps operations humming with fewer interruptions.
How to Improve Sorting Skills
Make it crisp and predictable, even when volume spikes.
Start broad, then narrow: Split items into internal, external, and urgent before drilling into departments or floors.
Label the space: Use clearly marked trays, shelves, or bins for each category, route, or timeframe.
Visual codes: Color tags or number codes make priorities visible at a glance.
Keep directories current: Update employee lists, department moves, and frequent external contacts.
Refresh technique: Short micro-trainings and quick huddles keep standards sharp; postal guidelines and internal SOPs are your baseline.
Automate when it makes sense: High-volume operations benefit from sorting equipment and barcode workflows.
Tune the process: Track where delays happen and adjust routes, bins, or cut-off times accordingly.

2. Packaging
Packaging covers prepping items for shipment—choosing the right box, padding, sealing, and labeling—so contents arrive intact.
Why It's Important
Well-packed shipments survive the bumps, which means fewer returns, less waste, and happier recipients.

Tough on protection, light on cost, neat on presentation.
Match materials to risk: Use sturdy cartons and right-size them; add corner protection for fragile goods; consider recycled options where possible.
Stop the rattle: Bubble wrap, paper, or foam that locks items in place prevents damage.
Seal like you mean it: Use shipping-grade tape; reinforce seams and stress points. Water-activated tape can boost security on heavier boxes.
Label with clarity: Large surface, clean area, no seams underneath; include return info and any handling notes.
Think sustainable: Right-size packaging, minimize void fill, and choose recyclable materials when available.
Standardize: Create quick guides for common item types, from fragile samples to bulk documents.
