Klaviyo Rebuilt Itself Around AI Agents. What to Turn On Before BFCM

In the first week of August, Klaviyo made three announcements that, taken together, amount to a redesign of what the platform is.

August 4: Composer, which had been generating campaigns since its public beta debut at K:LDN in late June, expanded to generate entire flows, segments, and push campaigns from a single prompt.

August 5, alongside Q2 results: Klaviyo announced it's acquiring Agency, the AI agent company founded by Elias Torres. Torres becomes Chief Product Officer and takes over the agent product line, with the deal expected to close in Q3. The same day, Customer Agent picked up a Conversational Agent Builder, Custom Skills, Simulations, and API access, and K:Social went to general availability.

August 6, almost as a footnote: a Figma integration and a Social Insights Analyst that reads your Instagram engagement and UGC.

You don't hire an agent-company founder as CPO to keep shipping email templates. Klaviyo has decided agents are the product. So with BFCM roughly 13 weeks out, the practical question isn't "is this the future," it's "which of these do I turn on before my biggest revenue quarter, and which do I leave alone until December."

Here's how we're calling it for our clients.

Turn on: Composer for drafting, with a human on final cut

The August 4 expansion is the real story. Composer generating a campaign was a copywriting assist. Composer generating a flow, trigger, timing, branching, emails, from one prompt is a builder assist, and flow builds are exactly the kind of pre-BFCM work that piles up in September.

Where it earns its keep right now:

• Drafting the flows you know you're missing. If your browse abandonment flow has been "on the list" since March, a Composer draft gets you 70% of the way in minutes. You spend your time on the 30% that matters: offer logic, brand voice, and where the flow forks for VIPs versus first-timers.
• BFCM variants of existing flows. Seasonal forks of your core flows are tedious to build by hand and exactly the kind of structured, well-specified task generation is good at.
• Push campaigns, if you're using Klaviyo push at all. Most brands under-invest here because building them felt like a separate skill. That excuse is now gone.

Pricing is credit-based with a slider, from a $14 per month introductory tier, and Klaviyo has been throwing in 10,000 free credits for the first 90 days. That's cheap enough to evaluate honestly during September sends.

The caveat we keep repeating: Composer builds on whatever is already in your account. Generated segments inherit your data hygiene. Generated flows inherit your deliverability posture. Our full Composer review covers the prompt patterns that work; the short version is that Composer is a fast junior builder, and you're still the reviewer.

Test now, decide by October: Customer Agent

Customer Agent was the underrated launch of the spring release, and the August upgrades address its two biggest adoption blockers.

Simulations let you run the agent against scenarios before it ever talks to a real customer. This was the missing piece. "Where's my order" is easy; "your BFCM discount code didn't work and I already checked out" is where an untested agent embarrasses you. Now you can watch it handle both before going live.

The Conversational Agent Builder and Custom Skills mean you can shape what the agent is allowed to do and teach it account-specific behavior instead of accepting a generic support bot. API access means it can plug into whatever else you run.

The BFCM calculus is a timing question. Cyber Week support volume is brutal, and an agent that deflects the routine half of it is genuinely valuable. But the setup, simulation, and transcript-review cycle takes weeks to do responsibly. If you start in early September, you can be confident by late October. If it's already November, wait until December and configure it in the quiet season instead.

Worth a look, not a priority: K:Social and the Figma integration

K:Social hitting GA plus the Social Insights Analyst (it reads your Instagram engagement and UGC and surfaces what's resonating) points at where Klaviyo is heading: one system that knows your customer across email, SMS, push, and social. The Figma integration does the same for design workflow.

If your team already plans social inside spreadsheets and your designer already works in Figma, these are quality-of-life upgrades worth trialing in a slow week. None of them will move your BFCM number the way flow coverage and deliverability will. Park them.

Two quieter items that actually matter

Stripe integration (July 28). If you sell anything off-Shopify through Stripe, subscriptions, digital products, services, that revenue and its events can now feed Klaviyo properly. For hybrid brands this quietly fixes a long-standing attribution blind spot before Q4, when you most want clean numbers.

France and Italy consent enforcement (July 13). Klaviyo now requires consent before tracking pixels fire for visitors in France and Italy. If you sell into the EU, check how your onsite tracking and signup forms behave for those visitors, because "abandoned cart" flows only trigger for profiles you're allowed to track. Better to find the gap in August than during Cyber Week.

What agents can't do, and why it's the whole game

Here's the pattern under every item above: the agent executes, the account decides.

Composer will happily build a beautiful flow on top of segments that are wrong. Customer Agent will faithfully follow skills configured around a returns policy nobody updated. The AI layer makes a well-structured account dramatically faster to operate, and it makes a badly structured account wrong at scale, with more confidence and higher volume than a human would ever manage.

Which is why our advice for the next 13 weeks hasn't changed shape, only urgency: fix the foundation first. Get your segments right, get your deliverability triaged, get the BFCM plan on paper. Then point the agents at it.

An agent can draft your flow in forty seconds. It cannot tell you that your engaged segment definition is inflated by Apple's privacy opens, or that 20% of your list should be suppressed before you 3x your volume. Finding that is diagnostic work, and it's exactly what our free Klaviyo audit does: a human review of the foundation the AI is about to build on, delivered in 48 hours. Get it done in August, and September becomes the month you switch the good tools on with confidence.
