From Static Automation to Agentic Marketing Execution
Klaviyo AI agents—Composer for marketing and Customer Agent for service—are autonomous tools embedded in a CRM platform that use shared, real-time customer profiles to audit campaigns, resolve support conversations, and feed signals back into cross-channel marketing automation agents, replacing brittle rule-based workflows with AI-driven decision-making across email, SMS, chat, and other surfaces. This is the real story behind their public beta launch: CRM is no longer just a place to store data or trigger flows, but a system that can decide what to do next and then execute it. That shift should matter to every retention and CX leader. If you still treat AI as a copy generator or forecasting widget, you will be slow compared with brands that let agents handle orchestration. The question is no longer whether to use AI, but whether you trust it with the actual work.

What Composer Actually Does: Not Copy, Orchestration
Composer is Klaviyo’s AI marketing agent, now in public beta, built to decide where to focus and then assemble full campaigns from a plain-language brief. It runs full audits of live campaigns, flows, and segments, then surfaces a ranked list of revenue opportunities—essentially pointing out underperforming automations and missed segments before stitching together the fix. Once you choose an opportunity, Composer builds the campaign across email and SMS: audience selection, cross-channel copy drafts, and send timing, with campaigns staged for approval rather than pushed live without review. The opinionated takeaway: this is “agentic marketing execution,” not AI copywriting. The value lies in saving lean teams from the drudgery of auditing flows and configuring segments at scale. For brands that drove more than $9 billion in ecommerce sales through Klaviyo in 2025, even small uplifts from better orchestration compound fast.

Customer Agent Turns Service Into a Data Engine
Customer Agent started as a prebuilt support bot; it is now framed as a Customer Agent CRM platform that spans marketing and service workflows, with a conversational agent builder, connectors, and open APIs. It can resolve common questions, complete returns, apply loyalty points, and work across web chat, email, SMS, WhatsApp, and custom surfaces, while writing back preferences, product interests, and intent signals to the customer profile when a conversation is resolved. According to Klaviyo, some brands now see about 65% of questions resolved automatically within 90 days—a number that turns service volume into a powerful source of segmentation data. The strategic point: support is no longer a cost center; it becomes a live intent stream that marketing automation agents tap into. If you keep service and marketing in separate tools, you are leaving behavioral data—size, color preferences, repeat issues—locked away from your campaigns.
Shared Real-Time Context: The Real Breakthrough
The most important design choice is that Composer and Customer Agent operate on the same real-time customer profile and event stream inside one CRM platform. When Customer Agent resolves a chat, it records preferences, intent signals, and product interests; Composer then uses those signals to build smarter email and SMS campaigns. When Composer launches a campaign, engagement data informs how Customer Agent personalizes the next interaction. This shared context finally addresses the messy handoffs between marketing and service that frustrate customers and waste revenue opportunities. In practical terms, it means a DM-based auto reply that captures an opt-in can flow straight into a segmented nurture, and the next support contact already “knows” that context. This is why Klaviyo argues businesses struggle not from a lack of AI tools, but from AI that cannot act on the context that matters.
Why This Matters Now—and What Comes Next
Composer public beta is available now, and Customer Agent is live as a full AI-powered service platform with more functionality scheduled throughout 2026. The timing is not accidental: CRM vendors are shifting from assistive widgets to agents that assemble campaigns, resolve tickets, and reuse learnings across channels. That evolution makes data hygiene and governance a growth risk. If your rules are messy, your policies inconsistent, or your edge cases undocumented, agentic marketing execution can amplify confusion instead of revenue. Teams will still need QA, holdouts, brand and legal guardrails, and clear escalation paths when automation should stop. My view is blunt: brands that treat these AI agents as co-workers—auditing them, coaching them, and feeding them clean data—will move faster and personalize better than those clinging to static flows. The CRM is now a co-pilot; if you do not trust it with execution, your competitors will.
