Klaviyo's New "Composer" Agent Builds Your Entire Campaign From One Plain-English Prompt — 193,000 Brands Are Already on the Platform
Klaviyo (NYSE: KVYO) launched Composer on March 24 — an AI agent that takes a single plain-language prompt and builds a complete, launch-ready omnichannel marketing campaign including audience segments, email copy, SMS messaging, channel selection, and timing optimization. Example prompt: "Build me a fun spring re-activation campaign targeting lapsed customers across email and text." In minutes, a full campaign is ready to review and approve. Every campaign Composer generates is grounded in Klaviyo's 14+ years of marketing intelligence and billions of consumer interactions across 193,000 brand customers — not generic templates. Human approval is required before anything goes live.

Alongside Composer, Klaviyo expanded its Customer Agent with new retail skills: order tracking, returns and exchanges, subscription editing, and loyalty lookup — all running on real-time customer data. New Agent Guidance controls let brands define voice, tone, and escalation rules so the AI always knows when to hand off to a human. Klaviyo co-CEO Andrew Bialecki framed the shift plainly: "The execution layer in software is moving from humans to agents."
🔥 80/20's Hot Take
Composer isn't a copywriting shortcut — it's a strategic acceleration layer. The difference is important. You're not replacing judgment; you're eliminating the execution tax that slows down the time between strategy and launch. But here's the Human Leader in the Loop truth: Composer is only as good as the brand guardrails, approval workflows, and voice guidelines you build into it. Set those well and you have a competitive weapon. Skip that step and you have a mediocre campaign factory running on autopilot.

Composer is a live case study for the "humans in the loop" debate. Klaviyo's co-CEO says execution is moving from humans to agents — but they still require human approval before launch. Ask: where exactly should humans remain in the loop in an AI-driven marketing stack? What does Klaviyo's model get right?

Google Used NewFronts to Show How Deep Gemini Now Runs Through Display & Video 360 — The "Ads Advisor" Can Build a Full Campaign From a Uploaded Media Plan
At IAB NewFronts this week, Google showcased how Gemini is now embedded across its entire marketing platform. The headline feature: a new Ads Advisor inside Display & Video 360 that can take an uploaded media plan and translate it into a full campaign setup with a single prompt. Also demoed: SKU-level conversion reporting in DV360, and a privacy tool called Confidential Publisher Match that connects first-party data with streaming signals from publishers like Roku without either party's data being exposed. Brands that added just one additional Google Marketing Platform product saw a 76% lift in return on ad spend according to Google's own data. That's the recruitment pitch.
🔥 80/20's Hot Take
Google's DV360 move and Shopify's Agentic Storefronts both point to the same truth this week: the infrastructure layer of marketing is being rebuilt around AI agents that execute decisions, not humans who operate tools step by step. The marketers winning in 2026 aren't the ones who know how to use the most tools — they're the ones who know which outcomes to define and which guardrails to set.
