New Klaviyo Updates Are ABSURD (Use These ASAP)

Klaviyo just rolled out a handful of updates that are game-changers for ecommerce brands. From real-time WhatsApp messaging to interactive SMS and even AI-driven channel optimization, these features are designed to help you get more out of your existing list and future-proof your retention strategy.

At ASPEKT, we’ve already started testing these updates across client accounts. Here’s a breakdown of the most impactful Klaviyo features you should be using in 2025 if you want to stay ahead.

WhatsApp Integration

WhatsApp is now natively available in Klaviyo, and it’s a big deal for brands selling internationally. If SMS has been your fast lane for conversions, WhatsApp is the autobahn.

With WhatsApp in Klaviyo, you can:

Trigger welcome flows with browse buttons.
Send campaigns directly in a chat thread.
Recover abandoned carts with product images and buy links.
Handle customer service and upsells in one conversation.

From Klaviyo’s beta test, brands saw a 22% higher opt-in rate and 2x revenue per recipient compared to SMS.

Pro tip: Collect WhatsApp opt-ins via your pop-up or checkout page, then send product recommendations complete with dynamic images and CTAs. It feels more personal, which drives higher engagement.

RCS Messaging

If you’re not familiar with RCS, think of it as the next generation of SMS. It allows for high-resolution visuals, tappable buttons, and even swipeable carousels inside a text message. Right now it works only for Android users, but Klaviyo automatically falls back to SMS for anyone else, so there’s no downside.

Here’s how we’re planning to use RCS at ASPEKT:

Product drops: Full images with a buy-now CTA.
Back-in-stock alerts: Verified logos, product visuals, and reply buttons.
Quick promos: One-tap replies like “Yes, send me 10% off.”

Instead of sending plain text, RCS creates a mobile-first shopping experience, bridging the gap between SMS and email.

Omni-Channel Campaign Builder with Channel Affinity AI

One of the biggest updates is Klaviyo’s new omni-channel campaign builder. It lets you plan, map, and deploy campaigns across email, SMS, and WhatsApp from a single visual board. Think of it as your campaign war room.

What makes it even smarter is channel affinity AI. This technology learns which channels each subscriber prefers and automatically routes them to the one that gets the highest response.

Example:

Day 1: You send an email.
Day 2: If the subscriber doesn’t open it, Klaviyo knows they usually click SMS, so it fires off a text automatically.
Day 3: VIPs might get a WhatsApp message, while app users receive a push notification.

This makes your campaigns adaptive and personalized without extra manual setup.

Multi-Touch Attribution

Ever wonder which email or SMS touchpoint actually contributed to a sale? Klaviyo’s new multi-touch attribution answers that question. Instead of giving all credit to the last click, it shows the full journey.

Why this matters:

You’ll see how welcome flows, abandoned carts, and product launches all work together.
You can justify increasing SMS sends when you see they assist conversions alongside email.
You can spot hidden trends by adjusting attribution windows.

For example, a cart recovery email might look underwhelming at first. But with multi-touch attribution, you may find it assisted 35% of conversions when paired with an SMS 24 hours later. This keeps you from scrapping flows that are actually driving impact.

AI Service Agent

Klaviyo’s AI service agent is like hiring a customer support rep that works 24/7. It pulls data from your product catalog, order history, and policies to answer questions, recommend products, handle returns, and even upsell.

Use case: Add the AI agent into your post-purchase flow inside the customer hub. It can automatically handle FAQs like shipping updates or return requests, while nudging the customer toward another purchase with personalized recommendations.

Other Notable Updates

While the five features above are the most impactful, Klaviyo has also released several smaller but useful updates:

Customer profile data: Store things like loyalty tiers or birthdays and trigger flows based on them.
Segmented content blocks: Show different modules to different customers dynamically in the same email.
Dark mode testing: Preview how emails render across inboxes in both light and dark mode.
Inbox opt-in buttons: Push subscribers to confirm their opt-in right after signup, reducing friction.
Gamified spin-to-win forms: While gimmicky, they can boost opt-in rates in the right context.
International SMS and smart translations: Streamline global messaging without extra manual work.
Conversational SMS: Run text-based quizzes that guide shoppers to the right product.
AI campaign planner and alerts: Automate campaign mapping, subject line testing, and get alerts when flows underperform.

Why These Updates Matter

Not every new feature will fit your brand today, but ignoring them means leaving money on the table. WhatsApp is already outperforming SMS in global markets. RCS makes SMS look and feel like a shopping app. AI-driven attribution and service agents simplify decision-making and save time.

The brands that adopt early will see the biggest gains in revenue and customer experience.

Quick Recap

Here are the Klaviyo updates worth testing in 2025:

WhatsApp integration for international, high-engagement messaging.
RCS messaging for richer, mobile-first SMS experiences.
Omni-channel campaign builder with AI for automated, adaptive routing.
Multi-touch attribution for true performance insights.
AI service agent for instant, scalable customer support and upsells.
