Review sender setup and list handling, then build an initial local-language nurture sequence. Focused on Thailand.
Research, channel development and digital marketing support
Thailand had 67.8 million internet users in October 2025, an internet penetration rate of 94.7 percent of the population. Commercial email in Thailand is subject to the opt-out rules under Section 11 of the Computer Crime Act and to the Personal Data Protection Act, whose consent rules are specific about how and when consent is given and which the PDPC actively enforces. The Email Marketing Starter for Thailand checks your list against those rules and builds a Thai-language sequence inside your existing platform.
Email in Thailand is governed by the PDPA’s consent framework and the Computer Crime Act’s opt-out rules, which put consent records and unsubscribe handling at the centre of the setup.
Under the Personal Data Protection Act B.E. 2562, consent relied on for marketing must be obtained before or at the time personal data is collected or used. It must be explicit, given in writing or by electronic means, and presented clearly apart from other terms rather than buried in a general terms-of-service checkbox. Contacts sourced from third parties, where the individual never dealt with your business, need particular care, and purchased lists are best avoided altogether.
Data subjects also have a statutory right to object to direct marketing. An unsubscribe request should therefore be treated as the exercise of that right, not simply as an email platform preference, and honoured promptly everywhere the contact is held. If your platform stores contact data outside Thailand, the PDPA’s rules on cross-border transfers may also apply, so data residency is confirmed during setup.
Thai-language emails generally perform better with a Thailand-market audience than English or machine-translated content, and Thai business readers are quick to notice copy that reads as translated. Where an English-speaking buyer group also matters, it is briefed as a separate track rather than mixed into the Thai sequence.
The core setup, applied to PDPA consent and Thai-language content.
We confirm and document how and when each contact consented, checking that the record shows explicit, timely consent presented separately from other terms. Contacts whose consent came through a bundled or pre-checked box are identified for re-permission before the list is used.
We define the audience and tone for the Thai content and write the approved copy directly in Thai for the buyer’s funnel stage. Any English track is briefed separately where the buyer group requires it, so neither version is simply a translation of the other.
We identify the permitted use of the audience, the privacy notices that apply and any cross-border processing questions raised by where the platform stores data. We do not assume a platform setting settles every legal requirement, and open questions are passed to your adviser.
We confirm who maintains audience permissions and suppressions after the starter work, who approves each send and how objections to direct marketing are processed across your systems. These responsibilities are documented so that they survive changes in the team.
These are the most common email compliance and performance gaps for Thailand.
A purchased or third-party-sourced list, where contacts never dealt with your business, has no PDPA-compliant consent record for your marketing. The Starter does not build a sequence on an unverified list, and inherited lists are reviewed before any use.
Consent collected through a pre-checked box inside general terms of service does not meet the requirement for explicit consent presented separately from other terms. This is a common gap in inherited lists, and the review looks for it specifically.
A literally translated English sequence reads as translated to Thai readers and tends to underperform. The sequence is written directly in Thai for the target buyer and reviewed in the platform layout before approval.
These inputs decide whether the list can be used as it is.

| Input | Why it matters |
|---|---|
| Platform and sending domain access | Required to configure authentication and build the sequence. |
| Contact list and consent history | Shows whether consent meets the PDPA standard or needs re-permission. |
| Brand voice, funnel stage and data residency | Anchors the sequence and shows whether cross-border rules apply. |
The engagement letter confirms the final deliverables and level of detail.
The current sender configuration, the authentication and platform changes recommended or made, and any outstanding dependencies such as DNS changes waiting on the domain owner. The findings explain why each item matters for delivery and who is responsible for it.
The approved copy for the initial nurture sequence, written in the target language and built in your platform for the selected audience, with market-specific labelling and unsubscribe handling applied. Test results for links, rendering and opt-out behaviour are included.
The audience rules, suppression handling, testing results and approval path for future sends, together with the structure and rationale of the sequence. Your team can use the notes to maintain the setup and build further sequences in the same way.
Engagements from Viettonkin’s published case studies. Each card states where the work took place and summarises what we did; the case itself gives the full context.
The Thailand branch of a European adhesive manufacturer wanted distributors for its office-use adhesives in Vietnam. We researched distributors of office stationery and supplies, built a curated contact list, introduced the client to them and reported on partner feedback.

An international consumer brand wanted to enter Vietnam without first building a local marketing team. We ran its digital strategy end to end: paid acquisition mix, content calendar, influencer sourcing and local channel selection.

It is necessary, but the request must also be honoured as an objection to direct marketing wherever the contact is held, not only in the email platform. The handover documents how that works.
No. Authentication supports delivery, but recipient engagement, complaints, reputation and mailbox-provider decisions also matter.
The starting point is the client’s existing platform. Feasibility and any required changes are assessed during scoping.
A purchased or scraped list rarely carries a consent record that covers your marketing and should not be used. An inherited list can be reviewed: segments with a documented consent basis may be usable, and the rest need re-permission first.
