The question is not whether brands should stop using WhatsApp. They should not. The better question is whether every entry, confirmation, validation request, reward notification and follow-up still needs to happen there.
From 1 October 2026, Meta has announced that service messages on the WhatsApp Business Platform will become chargeable. This affects the platform businesses use for messaging at scale, not ordinary personal WhatsApp chats.
For South Africa, the announced Meta rate is about US$0.0076 per paid service message, roughly 15c depending on the exchange rate, after the monthly free service-message allowance. Marketing messages cost materially more, at about US$0.0304, or roughly 61c per delivered message. Business solution provider fees, VAT and currency movements can increase the final rand cost.
Those amounts can look small in isolation. At campaign scale, they deserve closer attention. Fifty thousand entrants do not necessarily create fifty thousand messages. A journey may include an opening prompt, consent, data collection, proof-of-purchase upload, confirmation, retry, winner communication and reward fulfillment. The true cost is shaped by both audience size and journey depth.
WhatsApp remains exceptionally useful when reach, familiarity and conversational support justify the cost. It is well suited to customer service, complex enquiries and interactions where a person may need context, reassurance or a flexible response.
A competition entry is a different job. So is uploading a till slip, validating a purchase, checking eligibility, issuing a reward or returning to an incomplete entry. These are structured, repeatable interactions. A purpose-built campaign channel can often deliver them with greater cost predictability and more control over the experience.
WhatsApp gives brands access to a platform consumers already know. That lowers the learning curve, but it does not remove campaign operating costs. When message categories, follow-ups and provider charges are added, a familiar channel can become an expensive default.
The alternative is not to force consumers into an unfamiliar app. Brands can use a link or QR code to open a simple mobile web journey that feels conversational, works on entry-level smartphones and does not consume the consumer’s mobile data.
This matters in South Africa, where data affordability and device capability still influence participation. Reducing those barriers can broaden access while giving the brand a clearer view of the cost of each campaign interaction.
The most practical model is often a two-channel strategy. Keep WhatsApp where its reach and conversational strengths genuinely add value. Use a locally priced campaign platform for structured, high-volume journeys where the brand needs predictable costs, validation tools and repeatable workflows.
That may mean using paid media, packaging or social content to drive people directly into a campaign journey, while reserving WhatsApp for service, escalation or selected communications. It may also mean giving consumers a choice when both channels are appropriate.
This is not a technology decision in isolation. Marketing, customer experience, procurement and campaign operations should model the complete journey before selecting the channel. The right calculation includes message count, provider fees, build costs, fraud controls, support requirements and the value of the data collected.
Moving a journey away from WhatsApp only makes sense if the replacement is easy for consumers and useful for the brand. At minimum, marketers should look for:
Wina Wena is a data-free consumer engagement platform developed by Brazen Labs for competitions, rewards and ongoing brand campaigns. Consumers scan a QR code or follow a link into a familiar chat-style journey. They do not need to download an app, use WhatsApp or pay for mobile data.
The platform supports configurable buttons, text, images and video, as well as till-slip uploads, validation, fraud controls and custom data collection. It is designed to work on most smartphones, including many entry-level devices.
Its published connection price is R2,900 per month, including the first 10,000 messages each month, with additional messages at 10c. Campaign builds are quoted separately according to the journey required. Full details are available at www.winawena.com.
The value proposition is deliberately simple: easy for customers, lower costs for brands. It is not intended to eliminate WhatsApp. It gives marketers another option when a structured campaign journey should not inherit the economics of a general-purpose messaging platform.
WhatsApp will remain an important part of South Africa’s communications landscape. Its scale and familiarity are real advantages. But the arrival of paid service messaging makes automatic channel selection harder to justify.
Before the next competition or rewards campaign goes live, marketers should map the journey message by message. Which interactions need the reach and flexibility of WhatsApp? Which are predictable enough for a campaign platform? Where does the customer need a person, and where do they simply need a quick, data-free way to enter or respond?
When every message has a price, the answer is not to abandon a trusted channel. It is to make every channel earn its place.
