In India people search “bulk WhatsApp sender”. In Malaysia and Singapore they search “WhatsApp blaster”, and have for years. Same product category, different name, and two of the clearest direct-marketing regimes in Asia to run it under. This guide is written in the language the region actually uses.
What “WhatsApp blaster” means here
Two products, as everywhere. The desktop tools sold in Low Yat and on Carousell that automate WhatsApp Web from your own account, and official platforms on Meta’s API. The first kind is responsible for most of the region’s banned business numbers; the second is the one the rest of this guide describes. The one-second test is the same: if it asks you to scan a QR code from your phone, it is the first kind.
Malaysia: the PDPA, in practice
The Personal Data Protection Act 2010 requires consent for direct marketing and gives individuals the right to require you to stop. The 2024 amendments raised penalties and sharpened enforcement by the Personal Data Protection Department. Operationally:
- Consent with a notice, collected at checkout, in store via QR, or by a reply to a pre-filled message, stating what they will receive and in which language.
- Source, date and language recorded on the contact.
- Opt-out on every marketing message, honoured automatically and logged.
- No group exports and no bought lists. They are not consent.
The fuller Malaysian picture, including the campaign calendar and three-language templates, is in bulk WhatsApp marketing software in Malaysia.
Singapore: PDPA, DNC and the Spam Control Act
Singapore layers three things on WhatsApp marketing:
The practical answer is to build the list from consent and keep the record. See also the Singapore WhatsApp API provider guide.

What it costs
- Platform: $200 a year on WappBlaster, roughly RM 900 or S$270, for unlimited contacts, chatbot, inbox and API. A one-time “lifetime” blaster licence is cheaper on day one and costs the number by month two.
- Meta’s per-message charge: set per recipient country. Malaysia’s marketing rate is among the higher national rates on the 2026 rate card; Singapore is priced separately. Both billed per message, passed through at cost. Utility is cheaper, so confirmations and reminders should always go as utility templates. Service replies inside the 24-hour window are free today and become billable from 1 October 2026 (details).
Your number
Register a local number in each country you sell to. Malaysian and Singaporean customers both screen unknown foreign numbers, and a verified business name on a local number is what gets read. Setup is done with you on a call in English and takes two to five working days per number including Meta verification.
