Klaviyo Omnichannel Campaigns Just Cracked the Code on Email, and I’m Obsessed with It

The new Klaviyo Omnichannel Campaigns completely changed the game for email marketing, and it’s the best new feature I have seen in years.

In this post you will learn:

• What Klaviyo’s new Omnichannel Campaigns feature is and how it is turning email campaigns into coordinated multi-channel, multi-message sequences.
• How to set up and optimize Klaviyo omnichannel campaigns.
• Power moves to drive maximum revenue with Klaviyo omnichannel campaigns and a Klaviyo AI audience agent.

Klaviyo Omnichannel Campaigns vs. Traditional Email Campaigns

Most email marketers don’t want to admit it, but traditional email campaigns are dumb.

Not unsophisticated, just one-dimensional. You pick a list segment. You write a subject line. You hit send. And wait to see if the gods of the inbox smile upon you.

This blast-and-pray model treats every recipient identically, regardless of how they behave. Whether someone opened an email immediately, didn’t open it for three days, or lives in SMS but barely checks email, he gets the same experience.

Klaviyo flows are better, but even they are always-on automations, not coordinated campaign pushes. When you want to drive urgency around a product launch, a flash sale, or a seasonal moment, you’re back to a one-size-fits-all blast.

Or at least, you were.

Klaviyo Omnichannel Campaigns bring the dynamic, behavior-responsive intelligence of flows into the campaign format across every channel you care about. 

Email, SMS, push notifications, WhatsApp, and more. All designed, launched, and optimized from a single campaign builder. No stitching tools together. No channel silos. No guesswork.

Why care what I think? CustomersAI is an official Klaviyo partner that integrates directly with Klaviyo. Our AI retention suite optimizes email deliverability, increases audience engagement, and supercharges DTC revenue.

What Are Klaviyo Omnichannel Campaigns?

“Omnichannel Campaigns” is Klaviyo’s best new feature in quite a while. 

Omnichannel campaigns for ecommerce are a single marketing campaign designed in Klaviyo to send a sequence of multi-channel messages like email, SMS/text, push notifications, and WhatsApp from one unified interface. 

Omnichannel Campaigns let you reach contacts based on what they’re interested in and where they are engaging, without building a separate campaign from scratch.

• Traditional email campaigns: Manage single blasts to various segments on different platforms
• Klaviyo omnichannel campaigns: Use a visual user interface within Klaviyo to coordinate a multi-step, multi-channel, behavior-adapted customer engagement campaign. All from one place.

Email, SMS, WhatsApp, products of interest, openers/non-openers, clickers/non-clickers. You can reach people differently, at different times, in different contexts, based on recent interactions. 

A few things Klaviyo Omnichannel Campaigns can do:

• Someone opens your email? Great! Follow up with another or with an SMS. 
• Someone doesn’t open your email? Give them a break and stop sending unwanted emails that they won’t open anyway. 
• Have a customer who’s a WhatsApp person? Route them there. 

Additionally, Klaviyo Channel Affinity (Klaviyo’s AI predictive analytics that ranks a customer’s preferred marketing channels) analyzes each individual customer’s engagement patterns and dynamically routes messages to the channel they’re most likely to respond on.

What Are the Benefits of Klaviyo Omnichannel Campaigns?

Let’s talk about what omnichannel campaigns mean for your numbers.

• Get campaign-level agility with flow-level intelligence. Omnichannel Campaigns unifies campaigns and flows. You can run a time-sensitive promotional campaign that still responds intelligently to behavior.
• AI does the heavy lifting. Klaviyo’s Channel Affinity actively optimizes which channel each customer gets based on real-time engagement data. It also helps predict churn, identify new segments, and even write copy for A/B testing. Your team focuses on strategy.
• Your reporting finally tells the full story. Multi-touch attribution is one of the most underrated parts of this feature. Instead of email analytics in one dashboard and SMS in another, you get a unified view of which combinations of messages actually drove conversions. That’s how you make smart decisions about sequencing and spend.
• Improve team efficiency. No more jumping between tools to coordinate a multi-channel push. Plan, build, launch, and measure an entire omnichannel journey from one drag-and-drop interface. Brands like Glossier, Bala, and Nomad are already using this to scale personalized campaigns without scaling their teams.
• [Advanced] Unlock more revenue by priming Gmail priority delivery signals. Klaviyo’s Omnichannel Campaigns feature has enabled a new email strategy, and I’ll show you how our customers use it to increase engagement and revenue per email across a retention audience.

How Do You Set Up Klaviyo Omnichannel Campaigns?

Klaviyo’s setup process is more intuitive than you’d expect for something this powerful. Here’s the architecture:

Step 1: Create a new Omnichannel Campaign (Figures 1 and 2)

Step 2: Define your audience. Use Klaviyo’s segmentation to target high-intent or high-value customers based on behavior and profile attributes. Multi-audience orchestration lets you customize sequences and offers by segment, loyalty tier, or behavior All within the same campaign (Figures 3 and 4).

Step 3: Build your campaign journey. Map out your message sequence in the omnichannel campaign builder with a drag-and-drop interface that lets you visualize the full journey across channels, timing, and audience logic in one place (Figures 5-8).

Step 4: Let AI optimize delivery. Channel Affinity routes messages in real time to the channel each person is most likely to engage with. You just set the sequence logic.

Step 5: Measure and refine. Use multi-touch revenue attribution and channel-specific insights to adjust frequency, creative, or sequencing based on what’s actually driving conversions.

Klaviyo Omnichannel Campaign Power Move: “Engagement Stacking” with CustomersAI

Omnichannel campaigns for email, SMS, WhatsApp and more are a powerful feature, no doubt. Multi-threaded, multi-channel touchpoints will always outperform a one-channel approach.

But you can do more than sending email and SMS messages to a contact.

I’m going to show you a deliverability and email revenue-driving power move we developed that you can unlock using AI Omnichannel Campaigns using a predictive audience agent. We call it “engagement stacking.”

First, a little background on how the Gmail algorithm works.

Gmail has an AI and machine-powered algorithm for sorting a recipient’s emails within the primary inbox, the promotions tab, and the spam folder.

The Gmail algo is looking for things like:

• Are other people opening and clicking on emails that have similar content?
• Is this sender trusted?
• Have other recipients marked emails from this sender as spam?
• Do the contents of this email fit a known pattern of important, promotional or spam content?

In other words, when an email demonstrates signals that Gmail associates with an “important” email, Gmail will deem future similar emails to be important as well.

With this understanding of the Gmail algorithm in mind, consider the “engagement stacking” tactic.

1. Front-load a campaign with the most likely to open, click and purchase segment of a Klaviyo audience.
2. Gmail receives signals that is an important email.
3. Gmail delivers every subsequent email with the same content as though it is an email of high importance.

How Do You Know Which Email Audience Segment Is Most Likely to Open, Click and Buy?

Great idea in theory, but how do you know the audience segment that is most likely to open, click and buy? 

That’s where CustomersAI’s AI predictive audience agent, Alfred, comes in.

Alfred is CustomersAI’s list intelligence layer. It reads your entire Klaviyo account and uses machine learning to classify contacts into three buckets:

• Highly Engaged
• Recommend Suppress
• Recommend Reactivate

Alfred uses off-platform behavioral signals like anonymous site browsing, product views, and return visit frequency and syncs them back into Klaviyo as tags so you can build smarter send lists.

With this smarter send list, your first emails will go to your most engaged recipients, where they will have very high inbox delivery and open rates.

Gmail will take those signals and deliver emails to the inboxes (instead of spam or promotions) of your less engaged recipients, raising your success rates and your revenue per email.

Engaged recipients > Better signals > more revenue. That’s the flywheel.

Klaviyo’s Omnichannel Campaigns is the engine. CustomersAI Alfred AI predictive audience agent is the high-octane fuel that makes email perform to a higher potential.
