WhatsApp Marketing: A Comprehensive Guide

WhatsApp is among the top digital marketing tools because it’s accessible, practical and comprehensive. The app had more than 3 billion active users in 2025 and is the most widely used instant messaging app worldwide.

WhatsApp covers about 180 countries. Thousands of companies have use it as a marketing, sales, and customer service channel. However, many brands still view WhatsApp as a separate platform that doesn't require the same planning as other communication channels. While it generates results, this view reduces the omnichannel model and can put your business at a disadvantage compared with the competition.

In this article we'll explain what WhatsApp marketing is and why using the app alone isn't enough to implement this strategy. You'll understand:

• What exactly is WhatsApp marketing
• Why is it important to apply this strategy
• What are the benefits of WhatsApp for your digital marketing
• How to connect the app to the channels you already use (and how Salesforce can help with this process)

Created in 2009, WhatsApp became popular by as a free version of SMS messaging. With internet access and a linked mobile phone number, it was possible to synchronize contacts on the device and exchange text messages, audio messages, images and videos, as well as make phone calls and video calls.

In 2014, the app was acquired by Facebook (now Meta) for $22 billion. Initially, this move brought WhatsApp closer to social networks by introducing new features, such as status sharing (a feature of Snapchat and Instagram Stories) and image editing capabilities.

Later, as with Meta's previous acquisitions, certain new developments expanded its corporate use, culminating in the launch of WhatsApp Business in 2018. At that time, WhatsApp was already being used for scheduling services, executive meetings and even video conferencing.

However, the app already announced possibilities such as:

• Real-time customer service
• Promotion of products and services
• Customer loyalty initiatives (such as sending discount coupons and exclusive promotions)
• Direct contact with suppliers
• Closing sales and other commercial transactions

WhatsApp Business launched with a similar interface to the regular version and features that improved business interaction management. These are some of the app's main features:

When registering an account, the company can add a brief description and details such as segment, address, opening hours, website and primary email.

You can set up automatic messages to greet customers in chat, confirm receipt of messages, and communicate when agents are unavailable.

The company can create a portfolio within the app , including descriptions, photos, typical prices, and even featured offers for products and services.

Conversations can be tagged according to company criteria, classifying contacts as "customers," " prospects ," "suppliers," and more. Tags can also indicate the stage each negotiation is in ("proposal sent," "order received," etc.).

They allow you to send the same message to up to 256 contacts at once. They were created as an alternative to groups, to facilitate secure content distribution (only the company can send messages to its broadcast lists).

The company can create a portfolio within the app , including descriptions, photos, typical prices, and even featured offers for products and services.

According to Meta data, more than a billion users connect corporate accounts to the company's messengers every week – which reiterates WhatsApp's dominance as a channel for direct interaction and engagement, followed by Facebook Messenger and Instagram Direct.

WhatsApp for Business has brought benefits to small, medium, and large businesses. For small businesses, direct and personalized chat simulated normal customer interactions, and conversations were relatively simple to manage.

Large companies, on the other hand, were attracted by the platform's reach and faced some challenges. How can brands with a global customer base leverage a one-on-one interaction tool? If a WhatsApp account can only be accessed by one user at a time, how can they respond to hundreds of thousands of messages simultaneously?

Above all: how can we meet such a large demand without compromising personalized service?

The WhatsApp Business API was the solution launched to address these issues. The API provides large-scale customer service by connecting the app to other digital marketing technologies, such as chatbots, social media, and software like CRM and CDP.

In addition to automating processes and facilitating handovers to human agents, the API enhances WhatsApp campaign creation by retrieving data from other systems. It also grants a verification seal to linked accounts, reinforcing brand credibility.

In short, WhatsApp marketing is the strategic use of the app to promote a brand, its products, services, and actions, aiming to leverage customer relationships and generate value for the company.

You know that WhatsApp is a powerful marketing channel for promoting offers and strengthening customer relationships. However, not all promotional communication through the app qualifies as WhatsApp marketing .

To achieve this, messaging should be tailored to meet your business objectives. In other words, the app's use should fit within a broader marketing plan, linked to other channels and sales promotion strategies, content marketing, and relationship building.

Having this vision is essential because consumers do not use WhatsApp in isolation in their daily lives.

Between visits to the platform, users check their email inbox, Instagram feed, Facebook timeline, TikTok reels, and various other digital content sources. With their phones in hand, they can also navigate different channels, interacting with your brand through offline touchpoints .

So, it's best for your team to orchestrate multiple strategies simultaneously to optimize the chances of attracting the public's attention and having a positive impact.

Investing solely in WhatsApp or separating it from other marketing channels can:

• Decrease your brand visibility: If not completely ignored, your messages can get lost among countless conversations and available options.
• Lower conversions: Channels that attract audiences don't always retain their attention. And when they don't progress through the sales funnel , missed opportunities result in wasted resources.
• Increase the chances of spam: To avoid being forgotten, some brands bombard customers with messages, damaging their reputation without necessarily achieving results.
• Complicate the user experience: Although WhatsApp has a thousand and one uses, there are channels that can showcase your work and record interactions with customers in a more organized way.
• Create data silos: Having too many active channels and little exchange between them creates confusion, setbacks, and unnecessary effort for both the company and the customer.
• Fragment the brand persona: without a brand identity guide, rotating between agents can alter the tone and language of communication, conveying inconsistency.
• Overload your marketing team: With so many tasks to handle, your team can become disengaged and act less strategically, losing innovation and productivity.

You can see that WhatsApp without a strategy is more of a hindrance than a help, right? However, a digital marketing strategy without WhatsApp is also incomplete. This is because the app can be a leading or supporting player in an operation — it all depends on your goals.

It's important to understand the benefits of WhatsApp to determine what role the app can play for you. This role can be achieved throughout the entire purchasing journey, as long as communication is customer-centric.

Compared with email marketing, for example, WhatsApp guarantees nearly 100% delivery and a much higher open rate. This is because most users access the app daily. Meta estimates that more than 65 billion messages are sent through the app every day.

If the recipient's settings allow it, you can also confirm whether messages have actually been viewed. These features make this tool ideal for critical communications, such as bottom-of-the-funnel or timed deliveries (flash sale announcements, abandoned cart reminders, etc.).

After viewing the message, users can respond at their own pace and through a channel they already use (even more than their phone). Besides giving customers a certain level of autonomy, communicating via WhatsApp is natural, which increases the chances of feedback .

For companies, the ease of creating and converting a business account also plays a role in choosing the app.

With a simple and intuitive interface, WhatsApp has managed to bring together audiences of virtually all ages. To date, no other tool or social network has achieved such a broad reach in such a short time— a very important factor for brands investing in "numbers games" (campaigns that prioritize sales volume or market share ).

Furthermore, the app's evolution hasn't made it more difficult to manage . With a predefined strategy, operating the app itself doesn't require as much marketing and technology knowledge.

Have you noticed how viral memes and news often spread through WhatsApp?

This app is famous for its emphasis on sharing , driven by groups whose dynamics resemble word -of-mouth marketing . This represents immense potential for brands looking to generate engagement and strengthen a sense of community, whether among their own base or not.

Forget long minutes on the phone and days (or even weeks) waiting for an email. Just like you, customers want quick responses and simple solutions via WhatsApp.

This is the ideal way to streamline communication and speed up the sales cycle, using marketing automation to streamline tasks. Agility also encourages a more relaxed human exchange, enhanced by the use of emojis, GIFs, and stickers (within the bounds of professionalism, of course).

WhatsApp's free nature was one of its biggest attractions for the population compared with traditional text messages (SMS/MMS) and call centers.

It's important to note that integrating the app into an omnichannel strategy requires contracting services such as CRM software and a WhatsApp Business API provider. Even so, using the app is free and offers a significant financial return.

There are plenty of reasons to invest in WhatsApp marketing. Let's see how this strategy works in practice.

Let's say you have a business account set up, with complete information, welcome messages, and absence notifications. Your company likely uses WhatsApp to contact customers and qualified inbound marketing leads, who are attracted enough to provide their cell phone number.

Therefore, the first step is to respect the privacy of your contacts. Always prioritize relevance, disclose your cybersecurity measures, and, when planning your messages, be mindful of the frequency and tone of these messages.

We've mentioned WhatsApp several times as a highly personalized, high-impact channel. All your planning should consider the potential of conversations to better understand and delight your customers .

Therefore, your strategy should include actions and technologies that support contact segmentation. Remember that the massive use of WhatsApp can weigh on your budget, so you should optimize the effectiveness of interactions as much as possible.

Landing pages, WhatsApp redirect links (such as buttons and QR codes ), and even registration update triggers help obtain more complete data about users, associating the cell phone number with a series of other attributes and building a rich profile of each customer.

These tools can automatically connect to CRM software, such as Salesforce Marketing Cloud Next. Salesforce's features an integrated CDP, which facilitates list creation and feeds campaigns managed by the platform in real time.

Once you've defined your audience, you need to understand what you want to communicate – and what people would most like to hear from you.

Remember that WhatsApp is a conversational marketing channel; therefore, your brand should talk to customers, not preach at them. Define your WhatsApp marketing objective and assess whether your proposal aligns with customer expectations. For example, you could launch a solution suggested by your audience or provide guidance on joining an exclusive brand community.

Afterwards, conduct an audience study to determine:

• Conversation topics (vary depending on the stage of the customer journey);
• Message format and additional resources (audios, videos, campaign sticker pack , among other examples);
• Customer response protocol;
• Time slot and frequency of submissions (including for status posting);
• Triggers for sending messages (registration, sending orders, etc.).

We mentioned that a WhatsApp campaign is enhanced by its interface with other channels.

This strategy makes your placement less invasive and encourages you to "recapture" users who haven't engaged on other channels, increasing your chances of conversion.

Here are some ideas for applying this tip:

• Customers who engage via email marketing can be notified about promotions and launches more directly via WhatsApp
• Customers interested in specific products or services (product lines, items in the same category, etc.) can be notified about new collections and even included in cross-sell and upsell campaigns
• Customers who abandon their cart can be invited to complete their purchase, check out similar items, and take advantage of promotional periods (a strategy especially valid for holidays and sales)
• Customers who have expressed interest in unavailable items can be alerted about the restock and redirected to the product page

Personalization is the number one rule of WhatsApp marketing. But that doesn't mean starting every interaction from scratch.

Marketing automation serves both to speed up customer responses and to streamline campaigns. Because communication is asynchronous, customers can return at any time — and you should be prepared to follow up on the conversation.

Agents are essential in this regard, already capable of directing sales and performing more sophisticated operations. Another important measure is the creation of service templates. This involves mapping users' most frequent prompts and creating a predefined response that can be adapted as needed.

Imagine, for example, that your customers have been expressing interest in an out-of-stock item. When communicating the product's shortage, you can ask if they want to be notified about the restock and provide a direct link to the WhatsApp chat.

This is a simple idea of how the journey can be planned to consider this channel and provide a relevant solution that improves the customer experience.

In WhatsApp marketing, a significant portion of your target audience is already your customer. Therefore, it makes sense to use this channel in post-sale processes, such as follow-up and satisfaction surveys .

This is relevant from a marketing perspective because it influences the creation of new plans , such as brand loyalty campaigns and even entry into new markets. Conversational marketing initiatives generate valuable first-hand insights about customers, serving as a privileged channel for connecting with your base.

Design messaging solutions that support sales and service efforts. Because it's part of the Salesforce ecosystem, Marketing Cloud Next integrates with other cloud platforms, such as Commerce Cloud and Service Cloud, and can easily exchange data.

Congratulations: you've completed the entire WhatsApp marketing planning process! Now it's time to roll up your sleeves and implement what we've discussed to make the most of this channel.

Remember to set realistic and measurable campaign goals along with your objectives. With CRM software, your performance analysis will be facilitated by generating customized reports, updated in real time, and within the context of an omnichannel strategy .

Recalling the previous topic, always focus on interacting with your contacts to further refine this overview. And believe me: by striving for the best customer relationships, you'll continually improve the performance of your entire operation.

With each new version, the app brings benefits and features that reinvent the way we sell. To make the most of these new features, we need to think big and help people connect.
