Why we choose Klaviyo as the Best Email Marketing Platform for eCommerce

When it comes to email marketing platforms, there’s no shortage of options. From Mailchimp and Constant Contact to ActiveCampaign and HubSpot, each tool has its pros and cons. But when it comes to eCommerce specifically, Klaviyo stands out as the ultimate platform—and here’s why.

1. Built Specifically for eCommerce

Klaviyo wasn’t designed as a general email platform. It was built from the ground up with eCommerce in mind. This means everything—from data structure to automation—is tailored to online stores.

It integrates seamlessly with Shopify, WooCommerce, BigCommerce, and more, making setup and syncing data smooth and intuitive.

2. Deep Data Integration

This is where Klaviyo really leaves other platforms in the dust. It doesn’t just collect basic info like name and email—it tracks:

• Purchase history

• Browsing behavior

• Abandoned cart activity

• Average order value (AOV)

• Lifetime value (LTV)

• Predicted next order date

All of this data is available in real-time and can be used to segment, trigger flows, and personalize content. With Mailchimp or Constant Contact, you often have to rely on third-party apps or workarounds to get this level of detail.

3. Powerful Automation (Flows)

With Klaviyo, you can set up automated flows that are genuinely intelligent. These are just some of the flows you can easily build (and customize):

• Welcome Series

• Abandoned Cart

• Checkout Abandonment

• Post-Purchase Follow-Up

• Winback

• Birthday & Anniversary

• Browse Abandonment

• VIP & Loyalty Flows

Each flow can be tailored based on behavior, preferences, timing, and more. Platforms like Mailchimp offer basic automation, but Klaviyo takes it to a whole new level with granular control and logic-based branching.

4. Advanced Segmentation

Forget blasting your entire list. With Klaviyo, you can create hyper-targeted segments using behavioral and transactional data.

Want to email everyone who:

• Opened a campaign in the last 30 days and

• Added a product to cart but didn’t buy and

• Has spent over $200?

Easy. And you don’t need to be a developer to do it. The UI is friendly, and the results? Way more relevant messages = better performance.

5. Transparent, Real-Time Reporting

Klaviyo gives you crystal-clear reporting on how your emails and SMS are performing. You’ll see revenue generated per campaign, per flow, per recipient, and even per product. This is eCommerce-native reporting, built for marketers who care about ROI.

And unlike some platforms, Klaviyo doesn’t hide performance data or delay reports. It’s instant and actionable.

6. Native SMS Marketing

Klaviyo offers built-in SMS marketing, so you can run both email and SMS campaigns from the same dashboard, using the same customer data.

Why does this matter?

Because unified communication = better customer experience. And you can coordinate email + SMS together in one flow (ex: abandoned cart SMS sent 2 hours after email if no action is taken).

7. Scalability Without Complexity

Whether you’re just getting started or sending millions of emails a month, Klaviyo can scale with you. It offers robust features without requiring an enterprise-level team to manage them.

Some platforms claim to be “enterprise-ready,” but they’re often bloated, clunky, or just not intuitive. Klaviyo keeps things powerful and user-friendly.

8. A/B Testing & Deliverability Tools

Want to test subject lines, send times, or CTA buttons? Klaviyo makes A/B testing simple and powerful. You can test multiple variations and optimize for open rate, click rate, or revenue.

And in terms of email deliverability, Klaviyo offers advanced tools to manage your sender reputation, warming up IPs, and keeping your domain healthy.

If you're running an eCommerce brand and want to grow through email and SMS, Klaviyo is hands-down the best tool on the market.

It gives you the control, insights, and automation you need to deliver personalized experiences and drive serious revenue. Yes, there are cheaper options out there—but none match Klaviyo’s eCommerce-specific power, flexibility, and scalability.

Whether you're a startup or scaling to seven figures, this is the platform that grows with you.
