Automated < Autonomous: Klaviyo's 50+ feature drop
What Klaviyo's 50+ feature drop tells you about where lifecycle marketing is going — and if you’re running email and SMS for a DTC brand, you should be paying attention more than just the changelog.
Klaviyo is going all-in on AI-first CRM.
The foundation was laid last year. At K:BOS in September 2025, Klaviyo launched Marketing Agent — the autonomous strategist that plans campaigns, creates content, personalizes sends, and learns without prompting — alongside the broad release of Customer Agent for 24/7 personalized support. In December, they appointed Chano Fernández as Co-CEO effective January 1, freeing co-founder Andrew Bialecki to focus entirely on AI product development.
This January’s 50+ features aren’t the big strategic bet. They’re the proof that the bet is already being operationalized. The AI infrastructure is in place. Now Klaviyo is building the connective tissue around it.
What Actually Matters
Not all 50+ features are created equal. Here’s where I’d focus:
1. Personalized Send Time
(Jan. 8) Send time optimization is a tale as old as time, and even AI-driven send time optimization isn’t new conceptually, but Klaviyo integrating it natively means one less third-party tool, one less data handoff, one less point of failure.
2. Videos in Mobile Messaging
(Jan. 14) Video in messaging isn’t revolutionary. But native support across channels without third-party encoding or hosting removes friction. The question is whether your team has the creative bandwidth to produce video at the velocity messaging requires. The feature is almost ready. Most teams aren’t.
3. Shopify Markets Locale-Aware Catalogs
(Jan. 15) For brands selling internationally through Shopify Markets, this solves a genuinely painful problem. Syncing localized product catalogs — pricing, language, regional availability — directly into Klaviyo means your flows and campaigns can actually reflect what a customer in Berlin sees versus what a customer in Brooklyn sees. If you’ve been hacking around this with conditional blocks and workarounds, you know how overdue this is.
4. Social Auto-Replies
(Jan. 20) I’m excited to see Klaviyo’s acquisition of Gatsby, the third-party app that built its name doing exactly this — connecting social engagement to owned channels — make it into the feature releases this month. Gatsby allowed marketers to meet the acquisition moment where it happened, shortening the conversion path when the intent signal was high and neatly wrapped in an Instagram DM. Klaviyo’s CPO Adil Wali framed it as filling a gap that’s been hard to close.
”What Gatsby introduces is a layer of visibility that has historically been difficult to operationalize: real-time social engagement.”

If you were a Gatsby customer, you already know the playbook. If you weren’t, Klaviyo just made the on-ramp native. The feature is still in beta, but if you’re a socially active brand you should be testing this today.
The AI Agent Question
Marketing Agent and Customer Agent have been live since September, and the early returns are telling. Features like Coupon Retrieval — where Customer Agent instantly surfaces the right promo code mid-conversation — show how quickly these agents are gaining new skills (and valuable ones). The trajectory is clear: more autonomy, more channels, more decisions made without a human in the loop. That’s worth watching closely, because “autonomous AI that plans and launches campaigns in minutes” raises the question of what happens to brand voice, strategic nuance, and the kind of judgment that comes from actually knowing your customer.
I’ve seen what happens when brands ‘automate’ their lifecycle marketing. The team sets it and forgets it. The emails are technically correct and emotionally empty. The flows are optimized for open rates of the moment but stripped of anything that makes a human feel seen and are left there to decay for 6 or more months. The campaigns are frequent, ‘personalized’, and utterly forgettable.
AI agents will be extraordinary for the operational middle — the scheduling, the A/B testing, the segment building, the compliance checking. Where I’d hold the line is on the strategic edges. The campaign that takes a risk. The subject line that sounds like a person, not a model. The decision to not send an email because the moment doesn’t call for it.
The best use of these agents is probably the least exciting one: free your team from the operational grind so they can spend real time on the work that actually differentiates you.
The Bet
Lifecycle marketing has always been infrastructure. First-party data, zero-party data, CRMs, CDPs, ESPs, DMPs, custom events, profile properties, behavioral triggers, conditional splits, attitudinal filters, suppression lists, deliverability monitoring, sunset policies, preference centers, seed lists, engagement scoring, RFMT models, dynamic content, catalog feeds, inventory triggers, loyalty cadences, post-purchase sequences... I could go on, but you get it.
The whole point was automation and personalization. That battle was won years ago.
Klaviyo’s bet isn’t that the infrastructure gets better. It’s that the infrastructure starts thinking for itself. Automated to autonomous. That’s the line, and it’s an exciting one.
Just remember: your flows can be automated. Your voice shouldn’t be.
