How is RCS different from SMS and MMS?

RCS adds rich media, interactive elements, and verified sender profiles to the messaging experience. It’s delivered natively in the messaging app and includes features like read receipts and branded messaging, giving marketers a more engaging and secure way to connect with customers.

Will my messages still reach customers who don’t support RCS?

Yes. Klaviyo automatically falls back to SMS or MMS if a recipient’s device or carrier does not support RCS, so you never lose reach or message delivery.

Where is RCS available?

RCS is supported on most Android devices and major global carriers, and is now available on iPhone with iOS 18+. Klaviyo automatically detects device compatibility and will deliver your message via SMS if RCS is not supported, ensuring consistent reach and performance.

We are continuing to expand to new regions, but RCS is currently available in:

US, UK, DE, FR, IT, ES, PL, AT, SE, NO, and DK.

What are verified business profiles?

Verified profiles (also known as RCS agents) display your brand name, logo, and business information in the message thread. This builds trust with your audience and helps your messages stand out in a space increasingly flooded with anonymous texts.

Can I personalize RCS messages like I do with SMS or email?

Yes. RCS in Klaviyo is powered by the same real-time customer data and can be incorporated into any campaign or flow that you use for email and SMS, so you can personalize at scale without rebuilding your strategy.
