Using WhatsApp and RCS for marketing

Rich marketing campaigns

Both WhatsApp Business Platform and RCS allow businesses to create more engaging campaigns than traditional SMS. Instead of relying on text alone, you can include images, videos, documents and interactive buttons to encourage customers to take action.

Whether you’re launching a new product or offer, or sharing a limited-time discount, rich media helps capture attention and gives customers more ways to interact with your brand.

WhatsApp Business Platform also includes features such as product catalogues, carousels and click-to-chat adverts, making it easier for customers to browse products and start conversations without leaving the app.

Personalised customer journeys

Both channels support personalised messaging, allowing businesses to tailor communications based on customer information, preferences or previous purchases.

You can also automate messages based on customer actions, such as welcoming new subscribers, reminding customers about abandoned baskets or sending follow-up messages after a purchase. This helps businesses deliver more relevant communications while reducing manual work.

Customer service and automation

WhatsApp Business Platform and RCS both support two-way conversations, making it easier for customers to ask questions and receive support through a familiar messaging channel.

Businesses can also use chatbots to answer common questions, qualify enquiries and direct customers to the right team. This helps reduce response times while allowing staff to focus on more complex conversations.

Customer loyalty

Rich messaging channels are also well suited to loyalty and retention campaigns. Businesses can send personalised offers, early access to promotions, event invitations or exclusive content to encourage repeat purchases and strengthen customer relationships.

Interactive features such as buttons and calendar links also make it easier for customers to redeem rewards, register for events or respond to invitations directly from the conversation.

Should you choose WhatsApp, RCS or both?

WhatsApp Business Platform and RCS are both powerful messaging channels, but they’re suited to slightly different situations.

RCS is a strong choice if you want to reach customers through their phone’s native messaging app without asking them to download another application. If a customer’s device doesn’t support RCS, messages can automatically be delivered as SMS instead, helping improve delivery rates.

WhatsApp Business Platform is better suited to businesses looking for a more established marketing and customer communication platform. Features such as product catalogues, click-to-chat adverts, broadcast messaging and end-to-end encryption make it a flexible option for organisations running marketing campaigns at scale.

For many businesses, the best approach is to use both channels together. RCS helps extend your reach, while WhatsApp Business Platform offers additional marketing features and richer customer interactions. Using both allows you to meet customers on their preferred channel while delivering a more consistent communication strategy.
