Two-way text messaging

Two-way text messaging with RCS allows brands to go beyond static SMS blasts and engage in dynamic, interactive conversations with their customers.

While traditional SMS relies on one-word replies or keyword prompts, with two-way texting customers can respond using tappable buttons, quick replies, or natural language—all within the native messaging app. And with read receipts, typing indicators, and rich media support, conversations feel real-time, branded, and personal.

Whether you’re confirming an order, re-engaging a shopper, or answering questions post-purchase, RCS makes it easy to turn every message into a meaningful moment.

Implementing two-way messaging with RCS doesn’t just enhance the customer experience—it transforms how marketers build trust, engagement, and conversions.

Here’s what it unlocks:

– Personalized communication: Show customers your brand is listening with branded sender profiles, conversational replies, and typing indicators that mirror app-like chats.

– Faster responses: Suggested replies and action buttons remove friction, letting customers engage with a tap.

– Deeper engagement signals: Read receipts and click tracking provide precise insights into performance and interest.

– Campaign control: Interactive messaging lets you guide customers through product discovery, reordering, opt-ins, and more—without leaving the inbox.

RCS is a gamechanger for messaging. It turns the basic messaging thread into an interactive experience—supporting true, real-time conversations between your brand and your customer.

Here’s how RCS makes two-way messaging possible:

– Suggested replies and actions: Send messages that include pre-set response buttons (e.g., “Yes, I’m interested” or “Remind me later”)—making replies intuitive, fast, and trackable.

– Dynamic threading: RCS supports structured message threads, so you can build guided experiences like product recommendation flows, appointment confirmations, post-purchase feedback requests, and subscription management.

– No character code workarounds: No need for “Text STOP to opt out” or keyword-only replies—RCS enables natural-language interactions, making it easier for consumers to engage without friction.

– Rich conversational capabilities: Klaviyo’s upcoming RCS roadmap includes support for two-way messaging logic, automated flows, and personalization based on customer replies—unlocking new use cases for customer support, guided selling, and retention campaigns.

The result? A richer, more natural conversation that feels less like a broadcast—and more like a relationship.

Klaviyo’s RCS-powered two-way messaging is designed to make conversations scalable, measurable, and deeply personalized. It’s built on four pillars that unlock the full potential of mobile engagement:

– Build trust with a verified brand presence: Every message comes from a verified business profile, complete with your logo and contact info—helping customers recognize and trust your brand instantly.

– Optimize performance with real-time insights: Get native read receipts, click tracking, and fallback analytics across SMS and MMS, so you can test, learn, and improve with every send.

– Drive action and personalization with replies: Use suggested replies to gather zero-party data, personalize follow-ups, and trigger flows—turning every interaction into a conversion opportunity.
