Step-by-Step Guide:

  1. Open Templates: From your Clerk Chat dashboard, go to Templates → Create → RCS.

  2. Choose Your Layout: Select from hero images, multi-card carousels, or video cards — all optimized for RCS delivery.

  3. Customize Your Message:

    • Upload images or videos

    • Add a headline and short description

    • Add up to 3 interactive buttons (link, call, or trigger a chat flow)

  4. Preview in Real Time: Instantly preview how your message will appear across Android, iOS, and SMS fallback views.

    1. Test Internally: Send a test to yourself or your team to check design, functionality, and fallback content.

    2. Launch Your Campaign: When you’re ready, deploy it directly from Clerk Chat by hitting the + sign and selecting the template when writing a message.

Best Practices

  • Always include fallback text to ensure a clean experience for users without RCS support.

  • Limit to 2–3 buttons for the cleanest user experience

  • Test thoroughly on both Android and iOS views

  • Use consistent branding in your logo, colors, and message tone

  • Follow media specs to avoid display issues or carrier rejections

  • Leverage carousels to showcase products, promotions, or appointment types

  • Add descriptive alt text or video captions to ensure inclusivity.

Additional Template Features:

RCS templates support dynamic variables. Insert fields such as name, account info, or appointment details into your messages for a personalized experience at scale.

  • The RCS Template Builder now displays your company logo in real time as you design messages.

    • Ensures consistent brand representation

    • Shows exactly how messages (media, buttons, variables, and calendar links) will appear to customers in RCS-supported apps
