For years, "AI in your marketing stack" mostly meant a tool that suggested a segment or predicted what a customer might buy. Useful, but you were still the one doing the work: writing the brief, drafting the copy for each channel, lining up the timing, and answering the same "where's my order" question for the hundredth time.
This quarter, that changes for Klaviyo customers.
Now, Composer builds the campaign. Customer Agent resolves the ticket. Klaviyo Social Marketing turns followers into subscribers, then finds your top-performing content and the creators most worth partnering with. The full funnel production work that used to fill your week now runs on its own, grounded in your customer data, and nothing goes live without your sign-off.
The agents do the work, you set the direction. Here’s what we launched, and how it works.
Composer is now in public beta
Klaviyo's AI marketing agent, Composer, is now in public beta. Describe the outcome you want in plain language, and Composer builds a complete campaign, grounded in your customer data and past performance, ready for you to review in minutes.

Try "spring reactivation for customers who haven't purchased in 90 days, email and SMS, fresh tone," and it builds the audience, drafts the copy for each channel, coordinates the timing, and stages the send. You refine in follow-up messages and approve. Nothing goes live without you.
The difference is where Composer starts. A generic AI tool hears "win back lapsed customers" and writes a discount email that could belong to anyone. Composer is built inside Klaviyo, so it already knows who counts as lapsed for your business, what those customers respond to, and which brand rules to follow. You get a campaign that's ready to run.
Klaviyo customers get free credits to start, so you can build real campaigns against your own data right now. Get started.
Customer Agent becomes a platform you can build on
Customer Agent launched as an AI service agent. This quarter, it became a platform you can build on.
It still runs on the same profile as your marketing programs. When a customer reaches out, it already knows their order history, loyalty status, and purchase behavior, so it can resolve and recommend in the same conversation. Pre-built skills for order tracking, returns, recommendations, and loyalty mean you're live from day one.
And, Customer Agent is driving real business results. Naked Wardrobe reached 86% autonomous resolution within 90 days. NANUK saw a 100% increase in product recommendation, return, and exchange queries resolved within 90 days. Customer Agent resolves 65% of questions automatically.
What's new is how much you can now build yourself.
Conversational Agent Builder
With the new Conversational Agent Builder, you describe what you want in plain language, and Klaviyo builds it for you. A running brand describes a "Find My Perfect Gear" quiz, and Klaviyo builds the entire experience: the questions, the logic, and the recommendations, with no engineering or manual work required.
The quiz can also enrich your customer profiles as it runs. When a shopper tells the agent their favorite size, color, or activity, those details write straight back to their Klaviyo profile in real time, so every follow-up message and marketing email can speak to what they actually told you. Once it's built, test it before a single customer sees it. Run simulations and see how the agent responds. If something's off, click "Improve," describe the fix, and it updates itself.
Pre-built connectors and open APIs
Pre-built connectors let the agent act in the systems you already run, so it doesn't just talk about a subscription change, it makes the change.
And the open APIs mean Customer Agent isn't limited to Shopify. If you run a headless or fully custom storefront, you can embed the agent right into it, so the same resolve-and-recommend experience shows up wherever your customers already shop.
Customer Agent now speaks more than 100 languages
Customer Agent now also speaks your customers' language, more than 100 of them, across web chat, email, SMS, RCS, and WhatsApp.
This is what B2C AI service looks like when it's built on your data. Get started with Customer Agent now.
More access to Klaviyo Social Marketing
You built that following on your social platforms, but you don't really own it. One algorithm change or one lost account, and the audience you worked for is gone.
That’s because your social followers don't belong to you. Your subscribers do, and Klaviyo Social Marketing is how you turn more of those followers into subscribers, turning social engagement into customer growth.
Klaviyo Social Marketing connects what happens on social platforms, like Instagram DMs, comments, and mentions, directly to your unified Klaviyo profiles, so you can build targeted social segments, trigger flows to nurture top creators, and bring your best-performing posts into campaigns.
Get started for free by capturing email, text, and WhatsApp opt-ins directly from your DMs with Social Auto-replies. Set up a keyword-triggered reply, and when a follower responds, Klaviyo captures their consented email or phone number, so that they’re ready to enter your welcome flow.
The paid plan adds even more ways to grow, including
- Rich social engagement events you can use to segment, trigger flows, and personalize campaigns
- Webhook events to loyalty platforms, so you can reward top creators and engagers
- A social content library that centralizes all of your top user-generated content (UGC) and owned posts
- AI insights that automatically identify your best content and highlight who to partner with next
- Custom questions to capture preferences and interests from right inside auto-replies
- One-to-many Instagram account support.
