Traditional post works well for some businesses — but when timing, reliability, and security matter, a courier service might be the better fit. Here’s how they compare:

• Urgency – Couriers offer same-day or next-day delivery, while post is often 2–5 days.
• Value – If your item is high-value or time-sensitive, it’s safer with a courier offering tracking and insurance.
• Flexibility – Couriers pick up from your door. No need to wait in line at the post office.
• Proof – Most postal services offer no more than a delivery scan. Couriers give you signed or photographic PoD.
• Support – With a courier, you can call and speak to someone. That’s rarely an option with large postal carriers.
  In short: use post for non-urgent letters and bulk mailings. Use a courier when speed, care, and confirmation matter.
