Whatsapp has about 200 million users in Southeast Asia and is the preferred messaging platform in Singapore, Malaysia, and Indonesia. When you combine that with a 98% open rate, businesses would be hard-pressed to find a better marketing channel in the region. In this guide, we’ll explore WhatsApp marketing campaigns—what they are, how they work, and the strategies that drive actual results.
What is a WhatsApp marketing campaign?
A WhatsApp marketing campaign is a targeted messaging strategy that businesses use to reach customers through WhatsApp. It involves sending promotional messages, updates, or automated responses to engage audiences, drive sales, or improve customer relationships.
Depending on the business goal, these campaigns can be one-time broadcasts, automated workflows, or interactive conversations. Below are some common examples of WhatsApp marketing campaigns:
Promotional campaigns and product launches
Abandoned cart recovery and retargeting
Event or webinar reminders
Customer support automation
Loyalty programs and engagement
How it works:
Businesses use WhatsApp Business API or the WhatsApp Business App to send messages.
Messages include text, images, videos, product catalogues, and interactive buttons.
Campaigns can be manual (broadcasts) or automated (chatbots, scheduled messages, drip campaigns).
Businesses can track engagement and measure their WhatsApp ROI through read rates, replies, and conversions to optimise future campaigns.
How to use WhatsApp for marketing in 7 steps
To use WhatsApp for marketing, set up a WhatsApp Business account, collect opt-ins, segment your contacts, and get message templates approved. Then send campaigns, automate replies, and track results. The steps below cover each one
1. Choose the free app or the WhatsApp Business API
The free WhatsApp Business app suits very small businesses. You get a business profile, a catalogue, quick replies, and broadcast lists, but each list is capped at 256 contacts, and only people who saved your number receive your broadcasts. The WhatsApp Business API, accessed through a provider like SleekFlow, lets you message large opted-in lists, give your whole team access, automate conversations, and connect your CRM. Our WhatsApp Business API guide compares the two in detail.
2. Complete your business profile
Add your logo, business description, address, opening hours, and website, so customers know they're talking to the real business. If you qualify, you can also apply for a verified business badge.
3. Collect opt-ins
WhatsApp only allows marketing messages to people who have agreed to receive them. Collect opt-ins with a checkbox at checkout, a website form, a QR code on packaging or in-store, or click to WhatsApp ads on Facebook and Instagram. Keep a record of when and how each person opted in.
4. Segment your contacts
Group contacts by purchase history, interests, or how recently they engaged, so each campaign only reaches people it's relevant to. Fewer, more relevant messages also protect your number's quality rating, which drops when people block or report you.
5. Get your message templates approved
Marketing messages to customers who haven't messaged you in the last 24 hours must use a template that Meta has approved. Give each template a clear offer and one call to action, and add buttons, images, or product cards where they help.
6. Send campaigns and automate replies
Send broadcasts to your segments, and set up automated flows for moments that repeat, such as welcome messages, abandoned carts, and back-in-stock alerts. Hand the conversation to a person whenever a customer needs one. For ready-made campaign messages, see the templates in our WhatsApp broadcast guide.
7. Measure and improve
Track delivery, read, click, reply, and conversion rates for every campaign, along with opt-outs and blocks. Use the results to refine your segments, timing, and offers. Our guide to WhatsApp marketing ROI explains how to tie campaigns to revenue.
How much does WhatsApp marketing cost in Singapore?
The free WhatsApp Business app costs nothing. With the WhatsApp Business API, you pay Meta for each message delivered, plus your provider's platform fee.
Meta charges per delivered message, at a rate set by the message category and the recipient's country, so messages to Singapore numbers are billed at Singapore rates. Marketing templates are usually the most expensive category.
Since 1 Oct 2026, Meta also charges for service messages, the free-form replies you send within 24 hours of a customer's message, after the first 1,000 a month for each phone number. Utility templates sent inside that 24-hour window are charged too.
When someone messages you from a click to WhatsApp ad, replies inside the free entry point window are free. Meta's pricing page says the window can last a maximum of 7 days.

How to use WhatsApp at every stage of the marketing funnel
SleekFlow goes beyond being a WhatApp Business API platform. It is an omnichannel conversational AI suite designed to help businesses scale their sales, marketing, and customer engagement efforts.
Using SleekFlow through the marketing funnel
Rather than just sending messages, an effective WhatsApp marketing strategy guides potential customers through a structured marketing funnel, from awareness to conversion and long-term loyalty.
The marketing funnel represents the different stages a customer goes through before purchasing. It starts with awareness, where potential customers first learn about your brand, and moves to interest and consideration, where they evaluate their options. Then comes conversion, where they decide to buy, followed by retention, where businesses nurture relationships to encourage repeat purchases.
SleekFlow seamlessly supports each stage of this journey, ensuring that brands can attract, engage, and convert customers with strategic messaging and automation. Here’s how:
For awareness: Click-to-WhatsApp (CTWA) ads
At the top of the funnel, it's all about attracting potential customers. SleekFlow integrates with Click-to-WhatsApp ads, allowing you to:
Run targeted Facebook and Instagram ads that direct users to WhatsApp with a single click.
Automatically start conversations with prospects through chatbots or live agents.
Capture first-party data for future retargeting.
For interest: WhatsApp broadcast messages
Once potential customers are aware of your brand, the next step is nurturing interest. You can do this with WhatsApp broadcasts, allowing you to:
Send personalised promotions, product updates, and educational content to segmented audiences.
Leverage high open rates (98%) to ensure key messages reach customers.
Use interactive elements like images, videos, and buttons to keep users engaged.
For consideration: retargeted WhatsApp campaigns
At this stage, prospects are evaluating their options. Re-engage potential buyers by using:
Automated WhatsApp follow-ups for abandoned carts, enquiries, or previous engagements.
Personalised offers based on browsing and purchase history.
Human agents to offer instant support and encourage customers to ask questions.
For conversions: checkout buttons and CTAs
Driving sales is seamless with SleekFlow. You can facilitate your customer’s check-out process with:
In-message CTAs and checkout links to reduce friction in the buying process.
eCommerce integration with platforms like Shopify to send cart reminders and payment links.
Automated purchase confirmations and order updates, enhancing the customer experience.
For retention: loyalty programme messages
Customer relationships don’t end at checkout. SleekFlow helps brands maintain engagement and boost retention through:
Personalised loyalty rewards and VIP offers via WhatsApp.
Automated reminders for membership renewals, repeat purchases, and referrals.
Interactive surveys and feedback collection to improve service and drive long-term customer loyalty.
