Yes, you can do marketing on WhatsApp, and businesses across Europe are already using it to reach customers directly on the world’s most widely used messaging app. WhatsApp Business marketing for companies gives companies the tools to send promotional messages, automate conversations, and build genuine customer relationships at scale, provided they follow the platform’s rules and obtain proper consent from recipients.
Ignoring WhatsApp is leaving a direct line to your customers unused
Most marketing channels are getting noisier and more expensive. Email inboxes are crowded, social media reach is shrinking, and paid ads require ever-larger budgets to deliver results. Meanwhile, WhatsApp sits on virtually every smartphone in Europe, with open rates that dwarf those of email. When customers already use WhatsApp daily to talk to friends and family, a well-timed, relevant message from a brand they trust lands in a completely different context than a promotional email. The fix is not to abandon your existing channels but to add WhatsApp where it makes sense: order confirmations, appointment reminders, post-purchase follow-ups, and targeted offers to opted-in contacts.
Treating WhatsApp like a broadcast channel will get your account banned
WhatsApp is not a mass email list. The platform actively monitors for spam-like behaviour, and users can block or report businesses with a single tap. Too many reports and your WhatsApp Business account can be restricted or permanently removed. The businesses that succeed on WhatsApp treat it as a high-trust, low-volume channel: they send messages that are genuinely useful, they only contact people who have explicitly opted in, and they make it easy for recipients to opt out. The shift in thinking is from “how many people can I reach?” to “how relevant is this message to this person right now?”
What is WhatsApp Business and how does it differ from the regular app?
WhatsApp Business is a separate application designed for companies rather than individuals. It adds a verified business profile, automated greeting and away messages, quick reply templates, and product catalogues. The WhatsApp Business API extends these capabilities to larger organisations, enabling integration with CRM systems, chatbots, and marketing platforms for high-volume, automated messaging.
The standard WhatsApp app is built for personal conversations between individuals. WhatsApp Business keeps the same familiar interface but adds tools that make it practical for customer communication. Small businesses often use the free WhatsApp Business app directly, while medium and larger organisations typically access the platform through the API, which requires working with an official WhatsApp Business Solution Provider.
One meaningful difference is scale. The free app is managed manually and works well for businesses handling a modest number of conversations. The API removes that ceiling and allows automated flows, integration with existing marketing stacks, and detailed reporting on message delivery and engagement.
What types of marketing messages can you send on WhatsApp?
WhatsApp marketing messages fall into two categories: session messages and template messages. Session messages are any messages sent within 24 hours of a customer contacting you first. Template messages are pre-approved message formats used to initiate or re-open conversations outside that 24-hour window, and they must be approved by WhatsApp before use.
Within those categories, the types of content businesses send include:
- Promotional offers and discount codes sent to opted-in subscribers
- Order confirmations, shipping updates, and delivery notifications
- Appointment reminders and booking confirmations
- Post-purchase follow-ups and review requests
- Personalised product recommendations based on purchase history
- Event invitations and registration reminders
- Customer service responses and support conversations
WhatsApp supports rich media, so messages can include images, videos, PDFs, and clickable buttons. This makes it possible to send a product catalogue, a discount voucher with a redemption button, or a video tutorial directly within the chat.
What are the rules and restrictions for WhatsApp marketing?
WhatsApp marketing requires explicit opt-in consent from every recipient before you send them any promotional message. You cannot import a contact list and start messaging people. Every contact must have actively agreed to receive WhatsApp communications from your business, and that consent must be documented. Sending unsolicited messages violates both WhatsApp’s policies and GDPR.
Beyond consent, WhatsApp enforces several additional rules:
- All outbound template messages must be submitted to and approved by WhatsApp before sending
- Messaging certain product categories is prohibited entirely, including tobacco, alcohol in some markets, gambling, and financial services in specific contexts
- You must honour opt-out requests immediately
- Message quality ratings affect your sending limits, so high block or report rates reduce how many messages you can send
From a GDPR perspective, WhatsApp marketing is subject to the same data protection obligations as email or SMS. You need a lawful basis for processing contact data, a clear privacy notice, and a straightforward way for people to withdraw consent.
How does WhatsApp marketing compare to email marketing?
WhatsApp typically achieves higher open rates and faster response times than email, but it reaches a smaller, more deliberately opted-in audience. Email scales more easily, costs less per message at volume, and has a longer history of marketing infrastructure and tooling. WhatsApp works best for high-value, time-sensitive communications where immediacy matters.
The two channels are not in competition. Most businesses that use WhatsApp marketing effectively also run active email programmes. Email handles newsletters, longer-form content, and broad audience communication. WhatsApp handles the moments where speed and a personal touch matter: a flash sale expiring in hours, a delivery that needs attention, or a service reminder the customer genuinely benefits from receiving immediately.
Cost is another distinction. Email marketing at scale can cost a fraction of a euro cent per message. WhatsApp Business API pricing is based on conversation windows rather than individual messages, with rates varying by country and conversation type. For high-volume campaigns, the cost per conversation is higher than email, which means WhatsApp performs best when the value of the interaction justifies the cost.
How do you build a WhatsApp contact list legally?
Building a legal WhatsApp contact list means collecting explicit opt-ins through channels your audience already uses. You cannot add people to a WhatsApp list without their direct, informed consent. Every opt-in must clearly state that the person is agreeing to receive WhatsApp messages from your business specifically.
Practical ways to collect WhatsApp opt-ins include:
- Adding a WhatsApp opt-in checkbox to your website sign-up forms, kept separate from email consent
- Including a WhatsApp opt-in option at checkout, alongside order confirmation preferences
- Running click-to-WhatsApp ads on Facebook or Instagram, where users initiate the conversation themselves
- Adding a WhatsApp link or QR code to printed materials, packaging, or in-store signage
- Asking existing customers during a service interaction whether they would like updates via WhatsApp
Each opt-in record should log what the person consented to, when they consented, and through which channel. This documentation is your evidence of compliance if a GDPR question ever arises. Never migrate an email list to WhatsApp and assume previous consent covers the new channel.
How can you automate WhatsApp marketing campaigns?
WhatsApp marketing automation works through the WhatsApp Business API connected to a marketing platform or CRM. Automated flows can trigger messages based on customer behaviour, such as an abandoned basket, a completed purchase, or an upcoming appointment, without manual intervention for each message.
Common automation scenarios include:
- Welcome messages sent when a new contact opts in
- Abandoned cart reminders triggered after a set time period
- Order status updates sent automatically as fulfilment progresses
- Re-engagement messages sent to contacts who have not interacted recently
- Drip sequences that deliver a series of messages over days or weeks
Chatbot integration adds another layer. A bot can handle common customer questions, qualify leads, or collect information before handing the conversation to a human agent. This makes WhatsApp practical for customer service as well as outbound marketing, with automation handling the volume and people handling the complexity.
The key technical requirement is API access through an approved provider. Most marketing automation platforms now offer WhatsApp as a channel alongside email and SMS, so you can manage campaigns, segment audiences, and report on performance from a single interface.
What results can businesses expect from WhatsApp marketing?
WhatsApp marketing typically delivers strong open and read rates compared to email, largely because messages arrive in an app people check frequently throughout the day. Response rates are also higher when messages are relevant and personalised. However, results depend heavily on message quality, audience relevance, and how well the channel fits the specific use case.
Businesses tend to see the strongest outcomes when WhatsApp is used for transactional and time-sensitive messages rather than bulk promotional broadcasts. A shipping update or appointment reminder is welcomed. A generic promotional message sent to a large list is more likely to generate opt-outs or reports, which damages your sender quality score and restricts future sending.
The most realistic expectation is that WhatsApp will outperform email on immediacy and engagement for the right messages, but it will not replace email for volume or breadth. Treat it as a precision tool for high-value moments in the customer journey, and measure success by conversion rates and customer satisfaction rather than raw reach.
