Let's be honest, keeping up with the latest marketing trends as a DTC founder can be exhausting. But if you want to win in 2026, you can't afford to put all your eggs in one basket anymore. The brands that are standing out have moved beyond just sending a weekly newsletter or occasional text. They're showing up everywhere their customers are (email, SMS, WhatsApp, push notifications) and personalising the channels and frequency to the specific subscriber.

That's where Klaviyo comes in. It's hands-down the best platform for pulling off an omnichannel strategy without getting overwhelmed by tech or duct taping several different tools together.

In this article, I'm walking you through exactly how to build your next campaign across every channel that actually matters. By the time you finish reading, you'll have a campaign ready to launch and a repeatable system to make sure every future campaign hits all your customers, wherever they're paying attention.

WHAT IS AN OMNICHANNEL MARKETING CAMPAIGN?

Most marketing campaigns focus on one single channel, or when they involve multiple channels, they're often siloed and treated separately. An omnichannel marketing campaign exists across multiple channels such as email, WhatsApp, SMS, and push notifications, ensuring a single consistent message across all of them while tailoring delivery to the channels each individual subscriber responds best to.

This makes your campaign much more effective and far easier to track, especially when all of your stats live within a single platform that follows your customer across all channels plus their activity on your site.

The best results come when this is linked to your other marketing touchpoints, social media, on-site messaging, or even direct mail, so customers see a single, unified message no matter where they encounter you.

CASE STUDY: OATSOME

I'll be honest, I used to be really bad at eating breakfast. Between packing orders and marketing my business, I'd be lucky to eat before lunch. Thankfully, I'm a little less frantic running my service business now, and I've found simple breakfasts that don't take up my time. That's exactly why I love businesses like Oatsome.

They spotted busy people like us (founders, marketers, hustlers) and created smoothie bowls ready in 60 seconds. But it wasn't just their product that won. It was their omnichannel strategy. Their winback flow combines surveys, WhatsApp messages, and even physical postcards (via a Klaviyo integration with Deutsche Post). The result? A 50% open rate and double the revenue.

What made this work wasn't complexity for the sake of it, it was a single, cohesive message delivered wherever their customer was most likely to pay attention.

WHY KLAVIYO IS BUILT FOR THIS

There are plenty of platforms that claim to be omnichannel. Most of them mean they have an email tab and an SMS tab that don't really talk to each other. Klaviyo is different because it's built around the customer profile, not the channel.

Every action a subscriber takes, opening an email, clicking a link, browsing a product, abandoning a cart, replying to an SMS, all feeds back into a single unified profile. That means when you're building a campaign, you can use that data to decide who gets what message, on which channel, and at what time. That level of personalisation used to require a team of developers and a five-figure tech stack. Now it's genuinely accessible to a DTC founder running a lean operation.

HOW TO BUILD YOUR OMNICHANNEL CAMPAIGN IN KLAVIYO

Here's the exact framework I use when building omnichannel campaigns for my clients, and that I use in my own business. Think of it as five phases.

1. Define your campaign goal and message

Before you touch Klaviyo, get crystal clear on one thing: what action do you want the customer to take? Whether it's a seasonal sale, a product launch, or a loyalty reward ,your entire campaign needs to ladder up to a single, clear objective. Every channel you use should reinforce the same core message, even if the format changes.

2. Segment your audience by channel preference

In Klaviyo, use your engagement data to identify how different customers prefer to hear from you. Some subscribers open every email but never click an SMS. Others bounce straight past email but respond to a well-timed WhatsApp message. Build segments based on this behaviour — not guesswork — and route people into the right channel from the start. This is where most DTC brands leave money on the table.

3. Map out your channel sequence

A typical omnichannel campaign might look like this: start with an email teaser 3–4 days before launch, follow up with an SMS on launch day for your most engaged subscribers, send a WhatsApp message on day two for those who didn't convert, and use a push notification on day three as a final nudge for app users. The key is to think of these as one connected experience, not four separate messages. Use Klaviyo's flow logic and conditional splits to prevent customers from receiving the same message on multiple channels at the same time.

4. Personalise at the channel level

Your email can carry long-form storytelling, beautiful imagery, and product carousels. Your SMS needs to be under 160 characters with a single link. Your WhatsApp message can include a short video or image. Your push notification needs a punchy six-word headline. Write each message natively for its channel — don't just copy and paste. The message is the same; the delivery is bespoke.

5. Track, suppress, and optimise

Once someone converts, suppress them immediately from the remaining steps of the campaign. There's nothing more frustrating as a customer than buying something and then receiving four more messages pushing you to buy it. Klaviyo makes this easy with goal events and flow filters. After the campaign wraps, pull a unified report across all channels to see where the revenue came from — and let that data shape the next one.

WHAT GOOD LOOKS LIKE: THE METRICS TO WATCH

When you're running an omnichannel campaign in Klaviyo, stop thinking in channel-by-channel metrics and start thinking in unified revenue attribution. Here's a quick benchmark breakdown to aim for across your channels.

Email: 35–45% open rate for engaged segments, 2–4% click rate. If you're below this, look at subject lines and send time.

SMS: 98% open rate (yes, really), but conversion is where it earns its keep. Expect 5–10% click-through on a well-timed, relevant SMS. Keep lists clean and frequency tight, two to four sends per month maximum for most brands.

WhatsApp: Early data is strong, 60–80% open rates for brands using it correctly, and response rates that email can't touch. Use it sparingly and conversationally, not as a broadcast channel.

Push notifications: Low effort to send, but opt-in rates can be low. Aim for personalised triggers over broadcast blasts, cart abandonment, price drops, and back-in-stock alerts convert far better than generic promotional pushes.

Pro tip: In Klaviyo, tag all of your campaign messages with UTM parameters and use the unified revenue reporting dashboard to see which channel combination drove the most attributed revenue, not just which channel had the highest open rate. Open rates are vanity; revenue is the metric.

THE MINDSET SHIFT THAT CHANGES EVERYTHING

Most DTC founders I work with approach omnichannel marketing as a complexity problem. "I can barely manage email, how am I supposed to add SMS and WhatsApp too?" The answer is: you don't add channels, you migrate from channel-thinking to customer-thinking.

When you build inside Klaviyo with the customer profile at the centre, when you're thinking about what this specific person needs to see next, based on their behaviour and preferences, the channels become secondary. They're just delivery mechanisms for a conversation you're already having with your customer.

That's the shift. And once you make it, the complexity melts away, because every decision has a clear answer: what does this customer need to hear, and where are they most likely to hear it?

READY TO BUILD YOUR FIRST OMNICHANNEL CAMPAIGN?

If you've been relying on email alone, or running campaigns that feel disconnected and reactive, this is your signal to change that. The brands winning on retention right now aren't spending more on ads, they're just getting better at converting and keeping the customers they already have.

Klaviyo gives you all the tools. The framework above gives you the process. All that's left is to build it.

If you want a hand getting this set up properly, whether that's auditing your current flows, mapping out your first omnichannel campaign, or building the whole system from scratch, that's exactly what I help DTC brands do through the Omnichannel Sprint. Get in touch and let's talk.
