No. Postal circular mailing does not require you to prepare addresses. Hongkong Post delivers based on your selected target areas.

In general, postal circular delivery is completed within 4 working days after posting. Saturdays, Sundays, and public holidays are not counted.

It includes the reference number, posting date, number of households, and delivery list—clear and reliable.

Yes! Print a QR code on the flyer so customers can scan and claim an e-coupon instantly (e.g., $50 off).
This helps you connect online and offline touchpoints, ultimately boosting sales and strengthening long-term customer relationships.

Postal circular mailing offers wider coverage (reaching multiple districts), saves manpower costs, and provides stable delivery timelines;
door-to-door delivery is better when real-time interaction is needed. Combining both can achieve “wide coverage + deeper engagement” for stronger results.

Postal circular mailing may be affected by extreme weather. Arrangements are typically as follows:

  • Normal operation: Signal No.1 / No.3 and Red Rainstorm Warning
  • Suspended or adjusted: Signal No.8 or above / Black Rainstorm Warning, services may gradually pause within 2 hours before the official warning takes effect
