Electronic Marketing Under Thailand’s New Computer Crime Act

CPO Magazine

Thailand’s amended Computer Crime Act, which took effect in May this year, has brought about much needed changes in the way businesses can conduct electronic marketing. Spammers will now face criminal charges and hefty penalties if found guilty.

The latest rules are in line with Thailand’s national efforts in digital transformation as part of the “Thailand 4.0” policy to develop the country into a value-based economy driven by technology and innovation. To further this goal, the Thai government is actively promoting digital platforms, research and development, and science and technology.

Earlier this year, the Electronic Transactions Development Agency (ETDA) also revealed that in 2016, Thai people will use the internet, on average, 45 hours per week or 6.4 hours per day.  Notably, 75.8 percent of that internet time will be spent on electronic messages.  This high usage volume has provided plenty of electronic marketing opportunities, which continues to be one of the most economical ways to conduct marketing in Thailand.

To facilitate this economic change, and to provide legal protection for online users, the government and the National Legislative Assembly have updated a number of key laws, including the Computer Crime Act. The Ministry of Digital Economy and Society is also developing subordinate regulations to support the Computer Crime Act. One noteworthy area of change has been to the legal restrictions on inappropriate electronic marketing, and particularly spam emails.

Electronic marketing offenses under Section 11 of the Computer Crime Act

Although Section 11 of the old Computer Crime Act prohibited sending emails or electronic data which had concealed or falsified origins that affected the normal operation of a recipient’s computer, it did not apply to electronic marketing spam – emails or electronic data that disturbed the recipients. To address this exclusion, section 11 of the new Computer Crime Act makes it an offense to send emails or electronic data that disturbs recipients, and which do not allow recipients to unsubscribe.

The Ministry of Digital Economy and Society also subsequently issued a Ministerial Notification for Characteristics and Methods of Sending Data Deemed Not to Cause a Disturbance to the Recipient, which defines the types of emails and data that are not considered to cause disturbances to recipients. The notification provides “safe harbor rules” for businesses to abide by in their electronic marketing campaigns, when emailing existing or prospective customers, business partners, or third parties.

Safe harbor rules under the Computer Crime Act

Under the “safe harbor rules”, a “sender” is defined as any person who intends to send company emails or data for commercial purposes, and any website, application or social media operator that advertises or supports the sending of such email or data. The rules do not apply to telecommunications business operators that act as intermediaries for transmitting such emails or data, in order to prevent undue criminal liability for these operators when third parties use their services and networks.

The following types of data are not considered to cause a disturbance to recipients:

  1. Data sent to another person as evidence of an agreed contractual transaction, or for compliance with the law, or for expressing a relationship or a legal relationship between each other;
  2. Data sent by government authorities that enforce the law, and for non-commercial purposes;
  3. Data sent by an educational institution, a charitable body, or other organizations, and for non-commercial purposes; and
  4. Data sent in a legal manner which does not violate any individual rights, and for non-commercial purposes.

Emails or data that are sent for commercial purposes, and do not fall under the scope of the above, are only permissible when the recipient’s consent has been obtained. The following conditions for opting out or unsubscribing must also be met:

  • The data must specify signs, details, and processes that will enable the recipient to opt out or unsubscribe from receiving such data, and must include technical measures that will enable the recipient to do so quickly.
  • A sender who receives a request to unsubscribe must cease sending data to the recipient immediately if possible, or, in certain circumstances, within seven days after receiving the request.
  • The process or request form for opting out or unsubscribing must not be conditional and must not divert the recipient to any additional commercial purposes (e.g. clicking on an opt-out link takes the user to other websites or sales distribution channels).
  • If the sender continues to send data to the recipient after a request has been made, the recipient may send a second written request by way of email, registered postal mail with a return address, or through other channels by which they can confirm receipt. If the sender continues to send data after receiving a request of this nature, they are deemed to be committing a spam offense.

Implications for electronic marketing

Under the new rules, an offense incurs a maximum fine of THB 200,000 levied against each single spam email. It is thus important for corporations that engage in online business activities to comply with the safe harbor rules and be cautious in their online communications to avoid potential exposure to this penalty.

As the new Computer Crime Act and subordinate regulations have only been in effect for a short period, it remains to be seen how requirements can be complied with in practice. There are a few interesting issues to consider, such as how a sender can obtain consent from a recipient, and whether implied consent is acceptable. It should also be noted that the safe harbor notification grants the permanent secretary of the Ministry of Digital Economy and Society the authority to interpret and consider any issues arising from actions under the notification, which leaves open the possibility of additional legislative changes in the near future.

On September 29, 2025, Thailand’s Office of the Personal Data Protection Committee (PDPC Office) published its Regulations on the Review and Certification of Binding Corporate Rules B.E. 2568 (2025) (the Regulations). The Regulations provide clarity on the PDPC Office’s approach to reviewing and certifying binding corporate rules (BCRs) under Section 29 of the Personal Data Protection Act B.E. 2562 (2019) (PDPA), and aim to facilitate international data transfers within a group of undertakings or enterprises (a “corporate group”). In conjunction with this development, the PDPC Office also approved BCRs for two companies operating in Thailand on September 30, 2025. This milestone represents the first concrete progress since the PDPC’s Notification on Criteria for the Protection of Personal Data Sent or Transferred to a Foreign Country pursuant to Section 29 of the PDPA B.E. 2566 (2023) came into effect in March 2024. Some key features of the Regulations are set out below. Categorization of BCRs BCRs are classified into two types: (1) BCRs for Controllers (BCR-C) and (2) BCRs for Processors (BCR-P). The category must be clearly specified when submitting the BCRs to the PDPC Office. Documentation Requirement The applicant must prepare and submit the application (a standard template may be provided by the PDPC Office in the future) along with supporting documents for review and certification in the Thai language. If the supporting documents are in a foreign language, a certified Thai translation should be provided. The translation must be notarized by a notary public or qualified person. Supporting documents may include, among others, a binding instrument such as an intra-group agreement, or a list of entities subject to the BCRs. Expedited Process Requirement Organizations with existing BCR approvals under the EU or UK GDPR, or from countries announced by the PDPC under Section 28, may apply through an

AI-generated songs are now making waves in Vietnam on platforms like TikTok, with tracks such as “Say mot doi vi em” quickly gaining popularity and sparking widespread attention. This phenomenon raises a host of legal and ethical questions: Who is the author of these songs? Can they be protected by copyright? Who is responsible if there is an infringement? These questions are becoming increasingly urgent as AI music becomes more mainstream in Vietnam. Copyright Protection for AI-Generated Music in Vietnam Under current Vietnamese law, copyright protection is reserved for works that bear the mark of human creativity. The 2022 amendments to Vietnam’s Intellectual Property Law reaffirm that only works created by humans are eligible for copyright. In practice, if a human meaningfully contributes to the creative process—by providing prompts, making selections, editing, or arranging—their contribution may be protected. However, if a song is generated entirely by AI without significant human input, it is unlikely to qualify for copyright protection. When an AI-generated song does not qualify for copyright protection, the question arises as to whether the person who writes the prompts, edits, or compiles the work can still be considered the owner of an asset under the Vietnamese Civil Code. According to Article 105 of the Civil Code 2015, assets include objects, money, valuable papers, and property rights. While AI-generated music that is not protected by copyright is not considered money or valuable papers, it may be regarded as an object (in the form of a digital file or recording) or as a property right if it can be possessed, used, transferred, or exploited for value. Use of AI-Generated Works Without Copyright Protection If a song is not protected by copyright, does that mean anyone can use it freely? Not necessarily. The absence of copyright does not mean the

On September 26, 2025, the Contract Committee under Thailand’s Consumer Protection Board issued a regulation that aims to standardize contracts and enhance consumer protection within the beauty and wellness industry. The Notification on Prescribing the Beauty Service Business as a Contract-Controlled Business B.E. 2568 (2025), which takes effect on January 24, 2026, requires business operators to use a prescribed standard contract in Thai and adhere to strict mandatory provisions and prohibitions. These regulations apply to operators across all in-person and online service channels, including via digital platforms. “Beauty services business” is defined as the provision of services under an agreement allowing consumers to receive a series of treatments, either over a set number of sessions or within a set period. This includes massage, spa, other methods for cleanliness, beauty, or care of facial or body skin, and weight control and body shaping—including services offered electronically. The law excludes surgery, liposuction, and medical treatments performed by licensed practitioners. The notification establishes the following key requirements: Mandatory contract and formatting. All contracts with consumers must use the standard contract form, in Thai, with clear, readable text (minimum font size of 2 millimeters, no more than 11 characters per inch), and include all essential terms from the annexed form. Contract execution. Contracts must be made in duplicate, with one copy given to the consumer at signing. For agreements concluded through electronic channels, the process must comply with the Electronic Transactions Act and use the same required terms. Digital platforms. Business operators who provide services facilitated through a digital platform as an intermediary are ultimately responsible for ensuring the consumer receives a compliant contract. Prohibited clauses. The law prohibits clauses that limit or exclude liability for damages to life, body, health, mind, or property resulting from breach of contract or a wrongful act;

As Vietnam accelerates its digital transformation, data centers have emerged as critical infrastructure supporting the shift toward a digital government, digital economy, and digital society. For businesses targeting Vietnam’s rapidly growing data center market, a clear understanding of the evolving regulatory landscape, compliance obligations, and government incentives is key to successful market entry and operation. This article provides a strategic overview of investment opportunities and key compliance requirements in Vietnam’s dynamic data center sector. Investment Incentives to Boost Data Center Growth Since July 1, 2024, organizations and individuals across all economic sectors have been encouraged to invest in and contribute to the development of data centers. By law, there are no restrictions on shareholding ratios, capital contributions, or foreign investor participation in data center and cloud computing services under business cooperation contracts. Currently, investment in AI data centers is classified as a specially incentivized industry, qualifying for preferential treatments and incentives in terms of investment, taxation, land use, and other related areas. Large-scale data centers, together with AI and cloud computing, are currently considered as strategic technologies and products for which Vietnam offers significant fiscal, tax, and land incentives to promote investment. Additionally, these large-scale projects may receive direct financial support from local development budgets for facility construction, technical infrastructure, and equipment procurement, subject to state budget provisions and applicable laws. AI data center construction projects also enjoy preferential treatment under customs regulations. Regulatory Approvals for Providing Data Center Services The 2023 Telecom Law and its guiding documents marked a significant milestone by classifying data center services as value-added telecom services. Under the law, a data center service is defined as a telecom service that enables users to process, store, and retrieve information via a telecom network through the leasing of part or all of a data center.
