Best omnichannel marketing platforms for eCommerce

Your customer browses on Instagram and adds your product to the cart using their phone. Then they get distracted. A text comes through, an email pings, it’s dinner time. Three days later, they finally buy your product using their laptop.

But along the way, they got an email, an SMS and a retargeting ad. Did those messages work together, or did they just pile up?

If you run email in one tool, SMS in another and paid social somewhere else, you know the pain. Three dashboards, three versions of the truth and no clear answer on what's actually driving sales.

An omnichannel marketing platform fixes that. It puts your channels, customer data and reporting in one place.

The hard part is choosing the right marketing technology for your online store. We’re guiding you through the process and comparing six of the best marketing platforms for ecommerce brands, from a full omnichannel suite to a simple email marketing platform. You'll get honest pros and cons for each, so you can choose the best one for you.

2. Omnisend: Ecommerce-first platform with email, SMS and push in one builder
3. ActiveCampaign: Marketing automation with 900+ integrations and a built-in CRM

How we picked the best

Your marketing technology affects how you recover abandoned carts, but it also affects how you win that second order. So we looked at the full customer lifecycle, not just the feature list.

• Channel range: Can you run email, SMS, push and social retargeting from one place?
• ECommerce integration depth: Does it pull purchase, browsing and cart data from Shopify, WooCommerce or BigCommerce?
• Email automation and flows: Can you build cross-channel flows that react to what customers do?
• Campaign management: Can you plan, send and track omnichannel campaigns from one calendar?
• Segmentation and personalisation: Can you segment by buying patterns, engagement and lifetime value?
• Revenue reporting: Does it show which channels made money, not just opens and clicks?
• Room to grow: Will it still suit you when your list doubles?

Now, let's break down these omnichannel platforms. 

1. Klaviyo: Best overall for growing eCommerce brands

Klaviyo is built for eCommerce. It connects email, SMS, RCS, mobile push and WhatsApp to your store data. Every message reflects what a customer browsed, bought or left in their cart. Its AI even predicts which channel each customer prefers.

Omnisend is built for online stores. Its single builder handles email, SMS and push notifications. You can create cross-channel workflows without stitching tools together. It also integrates directly with Shopify, WooCommerce and BigCommerce.

Its pre-built email automation is the standout. Cart abandonment, welcome and post-purchase flows are ready to go. You can drop SMS or push steps into the same workflow.

In a 2026 eCommerce marketing report from Omnisend, they found that “automations made up just 2% of all email sends, yet generated 30% of total email-driven revenue."

Drip pros and cons

Let’s compare the omnichannel marketing platforms

What’s the difference between omnichannel and multichannel?

The omnichannel vs multichannel question comes down to data. Multi-channel marketing means you're on several channels. Omnichannel marketing means those channels share data and work together.

Picture a multi-channel marketing setup. A customer buys a product at full price. An hour later, they get a 20% off email for the same product. Ouch.

Now picture an omnichannel setup. The purchase updates their profile instantly. The discount email never goes out. Instead, a friendly SMS with care tips arrives. Same channels, very different experience.

What to look for in an omnichannel marketing platform

The right platform depends on where your store is now and where it's headed. A brand turning over six figures a month needs something different from one sending its first welcome email.

Start with integration depth. Your platform needs real-time data from your store. That includes purchase history, cart activity and browsing behaviour. Without it, your marketing automation runs on guesswork.

Then look at channel coverage. Email alone isn't enough for most growing ecommerce brands. SMS, push and social retargeting each play a role in the journey. Decide whether you need them all in one tool.

Finally, be honest about capacity. Even the best platform won't help if nobody has time to build and test flows. Campaign management takes real hours every week. Factor in who will actually run it.

How to measure omnichannel marketing success

Open and click rates only tell you so much. You need to know which channels lead to purchases and how they work together.

Say a customer finds you through a social ad. Next, they get a welcome email. Finally, an SMS reminder seals the deal.

If your reporting only credits the last touch, you'll undervalue the ad and the email. That's why choosing attribution data you can trust matters.

Track these across channels for a clearer picture:

• Revenue from automated flows versus one-off campaigns
• Customer lifetime value by acquisition channel
• Conversion rate by message type (email, SMS, push)
• Repeat purchase rate within 90 days of first order

Omnichannel marketing platforms for eCommerce FAQs

What is an omnichannel marketing platform?

An omnichannel marketing platform runs your email, SMS, push and social campaigns from one place. Every channel shares the same customer data. So each message reflects what the customer has already done, wherever they did it.

How is omnichannel marketing different from multichannel marketing?

Multichannel marketing means using several channels. Omnichannel marketing means those channels share data and work together. An action on one channel shapes what the customer sees on the next.

Do I need a Klaviyo agency to run omnichannel campaigns?

Not always. A self service email marketing platform handles the basics well. But cross channel strategy takes real time and skill.

An ecommerce marketing automation partner like Refuel Creative handles setup and ongoing strategy. Your team can then focus on running the business.

Which omnichannel platform works best with Shopify?

All six platforms in this guide integrate with Shopify, but the depth varies. Klaviyo and Omnisend focus purely on ecommerce. Both pull in detailed purchase, browsing and cart data for behaviour-based automation.

How long does it take to see results from omnichannel marketing?

Core email automation, like abandoned cart and welcome flows, usually starts generating sales soon after launch. Bigger gains come from testing and refining over the following months. We tackle the high-impact automations first, so you see returns early.
