For years, marketing technology asked you to do more. More campaigns. More A/B tests. More channels. More segmentation. And for the most part, “more” meant more hours from your team, more tools duct-taped together, and more manual work disguised as “automation.”
That era is ending.
Klaviyo's newest release of tools and features introduces the next generation of AI agents built to actually do the work of marketing and customer service, not just suggest what you should do next.
It’s the latest step in Klaviyo’s vision for the autonomous B2C CRM: a platform where real-time data, intelligence, and agents work together so your brand can grow faster with fewer manual steps.
Here’s what’s new, why it matters, and what it looks like in practice.
Composer: full campaigns from a single prompt
Composer is a new agentic experience and it fundamentally changes how campaigns and flows get built. Describe what you want in plain language (i.e, “Run a winback campaign for lapsed VIP customers with a 20% incentive”) and Composer generates a complete, coordinated campaign.
Composer draws on 14+ years of marketing performance intelligence and data from billions of consumer interactions across 193,000+ brands to not just generate campaigns, but make decisions. It determines who to reach, what to say, when to send, how many messages to include, and which channels to use––based on what’s most likely to drive results.
It also learns from your own business. Composer analyzes your flows to identify what’s working and what’s not, then recommends optimizations to drive better conversion. It understands your brand voice, your visual assets, and your broader business context - so every campaign is both on-brand and optimized from the start.
Now, campaigns that used to take days and multiple steps to assemble can be created in minutes. The team that ran 3 campaigns a month can run 15. The idea that was shut down on Tuesday because nobody had bandwidth launches on Wednesday.
Composer is currently in private beta.
Customer Agent: smarter, more capable, across more channels
Customer Agent, built to autonomously answer customer questions and resolve issues, released three interconnected updates that make it a powerful solution for service teams.
Expanded pre-built retail skills
New out-of-the-box skills let you automate high-volume support from day one.
- Enhanced order tracking.
- Order editing.
- Subscription editing.
- Returns and exchanges.
- Loyalty lookup.
These are skills purpose-built for retail, and they run on the same data platform that powers your marketing so every response has full context about who the customer is, what they’ve purchased, and how they’ve interacted with your brand.
A new Skills page gives your team visibility into what’s automated and how each skill is performing.
Agent Guidance
Your AI agent should sound like your brand, not a generic bot. Agent Guidance gives your team control over tone, conversational style, decision-making rules, and escalation criteria so your automated support feels as intentional as your marketing.
Omnichannel expansion to WhatsApp and email
Customer Agent now works across chat, text messages, email, and WhatsApp. Your customers get help wherever they are, and you don’t need separate tools for each channel.
For brands trying to scale support without scaling headcount, you’re getting an AI agent with real customer context, real retail skills, and real brand controls across every channel that matters.
More features, channels, and ways to grow across the Klaviyo platform
Here’s what else is new to help your brand show up where your audience is.
RCS: branded, interactive text messaging
RCS brings rich, branded messaging into the native messaging app.
- Verified business profiles.
- Rich cards and carousels.
- Tappable buttons.
All of this is within the same flows and campaigns you already use in Klaviyo, so you need no new tools or separate setup.
RCS is generally available now.
Social auto-replies
Turn social engagement into owned list growth with automated replies on Instagram. When someone comments or DMs, instantly respond and convert them into a new subscriber.
Social auto-replies are available now.
Personalized send time
Every customer has a window when they’re most likely to open, engage, and convert. Personalized Send Time identifies that window for each individual and delivers your message at exactly the right moment, automatically.
Top-performing campaigns in Klaviyo saw a 35% lift in click rate when using this feature. It is generally available now.
Audience Optimization: Refine
Audience Optimization uses a predictive model to decide who should receive each campaign - before it’s sent. It scores every recipient’s likelihood to unsubscribe using real-time signals like engagement and behavior, then automatically removes high-risk profiles. No major competitor offers anything like it.
This is another layer of AI-driven personalization, alongside Personalized Send Time, Next Best Product, and Channel Affinity, that ensures not just the right message, offer, and timing, but the right audience for every message.
Campaigns continuously adapt based on customer behavior, not static segments. And with a built-in cooling period, previously excluded profiles can re-enter the audience over time - creating opportunities to re-engage with better timing and relevance.
This feature is currently available in beta.
Next best product in mobile channels
Personalized, dynamic product recommendations are no longer email-only. Next best product recommendations now work across text, mobile push and WhatsApp, delivering personalized suggestions in the channels with the highest open rates.
Next best product is generally available in email and mobile channels now.
Multi-Email Profiles
A single Klaviyo profile stores up to 5 email addresses, each with independent consent, suppression, and history. Less duplicate profiles, cleaner data, a complete view of every customer in one place.
This is the foundation for advanced identity resolution, and it will be generally available by the end of March 2026.
Customer Hub updates
Personalized Onsite Banners bring dynamic, individualized messaging to your storefront. These feature real-time, personalized content driven by who’s visiting.
WooCommerce support for Customer Hub is coming at the end of Q1 2026, extending personalized on-site service experiences to a wider range of ecommerce platforms.
The AI gap is already widening
Software is moving from tools you operate step-by-step to systems where agents do the work. And agents need two things to perform well: the intelligence to make good decisions, and the infrastructure to act on them.
Klaviyo is building both. Composer and Customer Agent are the intelligence layer. Real-time customer data, 350+ integrations, and 14 years of marketing performance data are the infrastructure. Together, they create a flywheel: more customers, more interactions, more data, better agents, better outcomes.
If you’re still assembling campaigns by hand across 3 different tools, or managing support with a ticketing system that can’t see your customer data, this release should make you pause. The gap between brands that adopt this kind of technology and brands that don’t is widening, and it’s widening fast.
What’s next
Composer is in private beta now. Customer Agent’s expanded skills are generally available. RCS, Personalized Send Time, and Next Best Product in text are live today.
If you’re already on Klaviyo, explore these features in your account. If you’re not, this is a good moment to see what you’re missing.
