Benefits of bulk RCS messaging

Verification

Brand registration allows you to receive a verification checkmark and make your messages stand out from the crowd. Customers will understand that they are receiving messages from a verified company.

Company information

RCS messaging allows you to edit the sender name. You can add a logo, profile cover, company description, website link, and contact details.

Built-in app

Google has added RCS to the standard Messages app on Android, where regular SMS messages are received. Your customers do not need to download a separate app, as they do with Viber, to receive next-generation messages.

SMS fallback (cascade)

If a customer’s device does not support Google RCS, a regular SMS can be sent. This allows you to deliver an important message to every customer.

You may have these questions

RCS messaging is a modern message format that has replaced classic SMS. Notifications are sent through the mobile network while supporting multimedia features — images, videos, call-to-action (CTA) buttons, product cards, and logos.

The main difference from messengers is that users do not need to install a separate app to receive messages. Multimedia RCS messaging works on most modern Android smartphones and is displayed immediately in the standard format. As a result, customers receive brighter, more informative, and more engaging content, while businesses get new communication opportunities.

Advantages of interactive RCS messaging compared to SMS and Viber

Compared to familiar ways of sending information, connecting RCS messaging for business provides a number of advantages:

  1. Branded sending. The message is displayed with the company logo and name. This increases recipient trust.
  2. CTA buttons. For example, buttons such as “Go to website”, “Request a call”, or “Pay”. The customer can immediately complete the target action.
  3. The ability to expand content in real time. You can add images, videos, and product cards. The message looks like a mini landing page inside the chat.
  4. Reports and delivery statuses. It is easy to track message sending and read times. This option simplifies counting customers who clicked the buttons.
  5. Bulk RCS messages have compared to regular SMS and Viber campaigns, a higher conversion rate. The service does not require downloading apps. The standard messenger preinstalled on the smartphone is enough.

Where interactive RCS messaging is used

Interactive RCS messaging is suitable for business tasks in various industries. It is used for appointment reminders, delivery notifications, or upcoming payment reminders. Customers see the information on time and can respond quickly.

Product advertising campaigns look modern and attract attention. You can add a photo, description, and a button redirecting to the website or order form to the product card. Request confirmations with details and the ability to immediately go to tracking or payment help the customer feel in control of the process. Surveys and polls allow you to collect feedback without calls or extra links. Personalized offers with a direct transition motivate customers to use a promotion or special discount directly from the chat.

Examples of RCS messages with buttons and images

Modern RCS messaging for business resembles a mini landing page. For example, a customer receives a message with a bright product photo, company logo, short text, and a “Buy” button. This format may look like this: [Product image] “Season’s new arrival — stylish headphones. High sound quality and comfortable wearing.” [Buy] [Learn more].

This is what a modern campaign looks like — one that actually works and brings more conversions.

Another example is a notification with buttons for choosing a service: “Reminder about your consultation appointment. Choose a convenient time.” [Book] [Call me back].

App-free communication makes these messages accessible to a wide audience, while button integration speeds up interaction.
