Email marketing is a vital strategy for brands aiming to directly promote their products or services and boost sales. It involves targeting consumers via email to enhance brand awareness and foster loyalty. While cost-effective, flexible, and efficient, email marketing raises privacy concerns. Companies must ensure they avoid crossing into unsolicited spamming.
This guide outlines the legal requirements for email marketing campaigns, associated risks, and tips for complying with privacy laws. Note that regulations vary by jurisdiction, so consulting a local lawyer for accurate legal advice is recommended.
Email Marketing, also known as Email Direct Marketing (EDM), is a highly effective digital marketing channel. It involves sending emails to past and potential customers to promote products or services. Common content includes:
With 296 billion emails sent and received daily (3.4 million per second), and a projected 4.3 billion active email users by 2023, email is a dominant communication platform. As 99% of consumers check their email daily, email marketing surpasses other digital strategies in reach.
Email marketing yields an average return on investment (ROI) of $42 for every $1 spent. Direct emails enable one-click purchases, unlike social media, which primarily fosters interaction. Studies show email orders have three times the value of social media orders, making it a powerful sales tool.
Email allows dynamic content like links, PDFs, blogs, and social media. For example, a promotional email can drive traffic to a new article while building personal connections. By analyzing demographics, businesses can tailor emails to specific customer groups, boosting engagement and loyalty for sustained revenue.
In most jurisdictions, sending unsolicited emails is illegal under privacy laws. “Unsolicited” refers to emails sent without the recipient’s request or verifiable permission.
Spam mail is unsolicited bulk email sent indiscriminately to a large recipient list, sharing identical content across all messages.
Spam emails, typically commercial, are sent after businesses collect email addresses through methods like:
For emails to be spam, they lack recipient consent, are sent en masse repeatedly, and often omit opt-out options. Despite low ROI and reputational damage, some businesses use spam due to its low cost. However, this risks blacklisting by internet service providers and emails landing in junk folders. Governments worldwide have introduced privacy measures to curb spam.
Anti-spam laws vary by jurisdiction. Consulting a local lawyer is essential to avoid liability. Below are guidelines for Hong Kong, the EU, and the UK.
In Hong Kong, the Unsolicited Electronic Messages Ordinance (Cap. 593) (UEMO) regulates unsolicited commercial electronic messages (e.g., via phone, SMS, MMS, fax, or email) with a “Hong Kong link,” defined as:
The UEMO excludes:
For messages under UEMO’s scope, businesses must follow these rules:
Senders must provide accurate contact details (name, address, phone, email) valid for 30 days post-send. If outsourced, identify the organization on whose behalf the message is sent (except for resellers). Information must be in English and Chinese unless the recipient opts for one language. If a Chinese name is unavailable, one language suffices.
Messages must include a clear unsubscribe statement in the prescribed language, ensuring:
Unsubscribe requests must be honored within 10 working days, with records kept for three years in their original or accurate format.
Subject lines must accurately reflect the email’s content.
Caller line identification must not be concealed (applies to phone/fax messages).
The Do-Not-Call (DNC) register, managed by the Office of the Communications Authority, blocks unsolicited messages to registered phone/fax numbers without consent. This excludes person-to-person marketing calls, governed by a voluntary Code of Practice.
Additional Guidelines: Businesses must not:
Penalty: Violating UEMO triggers an enforcement notice. Non-compliance may result in fines up to HK$1,000,000 and up to five years’ imprisonment.
Direct Marketing: Per the New Guidance on Direct Marketing, unsolicited emails to unidentified recipients or random numbers are not “direct marketing.” However, emails to named recipients fall under the Personal Data (Privacy) Ordinance (Cap. 486) (PDPO), requiring prior consent.

The GDPR, effective since 2018, mandates strict consent requirements.
Positive opt-in is required. Pre-ticked boxes are non-compliant.
Consent for marketing emails must be optional and separate from service terms, privacy, or cookie policies.
Maintain records of:
Users must easily withdraw consent at no cost, ideally via an unsubscribe link in every email.
The UK’s Privacy and Electronic Communications Regulations 2003, guided by the Information Commission’s Office, prohibits electronic marketing emails to individuals unless:
Sole traders and some partnerships are treated as individuals. Personal corporate email addresses (e.g., firstname.lastname@org.co.uk) may also require data protection considerations.
Add anyone who opts out to a do-not-contact list and screen contact lists against it before sending emails. Confirm unsubscriptions immediately, but avoid further contact, including re-opt-in requests.
If compliance feels overwhelming, consider hiring a marketing agency or online marketer. Their expertise can help manage email marketing campaigns while minimizing legal risks.
