As digital advertising costs continue to rise, many businesses in Hong Kong are rediscovering the value of offline marketing. Among the most trusted offline channels, the Hongkong Post Circular Service offers reliable delivery coverage, flexible geographic targeting, and the credibility of an official postal network.
Whether you’re launching a new business, promoting seasonal offers, or expanding into new districts, direct mail remains one of the most effective ways to reach potential customers. In this guide, we’ll explain how Hongkong Post Circular Service works, its key advantages, ideal industries, and practical strategies to maximise your campaign results.
What is Hongkong Post Circular Service?
Hongkong Post Circular Service is an unaddressed direct mail solution that allows businesses to distribute promotional materials directly to residential and commercial mailboxes within selected districts.
Unlike traditional addressed mail, businesses do not need recipients’ names or mailing addresses. Marketing materials such as flyers, brochures, catalogues, coupons, postcards and product samples can be delivered efficiently to targeted areas across Hong Kong.
There are two service options available.
Standard Circular Service
Businesses can freely select specific districts, housing estates or commercial buildings. Circulars are delivered to all eligible mailboxes that do not display a “No Circular Mail” notice.
The minimum mailing quantity starts from 1,000 copies, making it an affordable option for SMEs and startups.
Select Circular Service
For businesses seeking more precise audience targeting, Select Circular Service utilises PrismGeo demographic data to identify households based on lifestyle, occupation and consumer profiles.
Hong Kong’s population is segmented into 12 major lifestyle groups and 35 detailed audience categories, including first-time homebuyers, civil servants, senior communities and many other customer profiles. This solution is ideal for brands targeting highly specific customer segments.
Five Key Advantages of Hongkong Post Circular Service
1. Low Entry Barrier for Businesses
With a minimum distribution of only 1,000 copies, businesses can launch an offline marketing campaign without requiring a large advertising budget.
This makes it particularly suitable for SMEs, local retailers and newly established brands.
2. Extensive Coverage with Precise Geographic Targeting
Hongkong Post Circular Service covers over two million residential and commercial mailboxes throughout Hong Kong.
Businesses can target entire districts or narrow campaigns down to specific housing estates, buildings or newly completed residential developments.
This flexibility allows marketers to balance broad brand awareness with highly targeted customer acquisition.
3. Higher Engagement and Stronger Customer Trust
According to international direct marketing studies, physical direct mail achieves an average response rate of 4.4%, compared with only 0.12% for email marketing.
Unlike digital advertisements that can easily be ignored or blocked, printed materials require recipients to physically handle and read them, creating longer brand exposure and stronger credibility.
This makes direct mail particularly effective for industries where trust is essential, including healthcare, finance, insurance and education.
4. Reliable Delivery with Minimal Administrative Work
Flyer King manages the complete mailing process on behalf of clients.
Our team coordinates directly with Hongkong Post, with applications typically approved within one working day. We also ensure all printed materials comply with postal specifications before handling packaging, insertion and submission.
Delivery is usually completed within 4–5 working days after mailing.
Businesses save significant time by outsourcing folding, envelope insertion, printing preparation and postal administration, allowing internal teams to focus on business growth.
5. Flexible Design Options
Circular mail supports various formats and creative designs.
Businesses can include:
- QR Codes
- Promotional coupons
- Discount codes
- Product samples
- Event invitations
- Landing page links
Combined with Hongkong Post’s geographic delivery capabilities, brands can effectively target newly occupied housing developments or selected communities with highly relevant offers.
The official postal channel also enhances brand professionalism and customer confidence.
