What makes a great marketing automation app?

Omnisend and Klaviyo are ecommerce-focused marketing automation tools deeply integrated with Shopify.

Both tools have plenty in common. So you’ll need to pick one based on something more specific. Here are the differences you should consider:


Omnisend is a better choice if you don’t have experience working with marketing automation tools. Klaviyo has an intuitive interface, but you’ll need some previous experience to make the best use of its advanced features.

Feature set

Klaviyo offers a broader range of features. That said, Omnisend also offers a few features you won’t find on Klaviyo, such as the ability to create landing pages and gamified popups.

Email builder

Klaviyo and Omnisend’s email builders are neck and neck, though with a few differences. Omnisend’s email builder offers fewer templates but comes with more customization options. For example, you can use the Product Picker option to add products from your store to your email.


Both tools offer segmentation, but Klaviyo is a segmentation powerhouse. With Klaviyo, you can create unlimited segments, use as many criteria as you feel is necessary, and use as much data as you need for your email marketing campaign.

A/B testing

Omnisend allows A/B testing subject lines and sender names. On the other hand, Klaviyo allows testing almost everything, including email content, preview text, and send time.

Abandoned cart tracking

Omnisend uses cookies to track an item whenever a customer adds an item to their cart. This means it’s easier to track abandoned carts with Omnisend than with Klaviyo.

Klaviyo uses flow triggers and filters. You’ll need to set up a trigger event, following which Klaviyo will start tracking an abandoned cart. While you get many customization options while creating a flow, it can quickly become intimidating if you’re only getting started.


Both tools offer triggered and conditional splits and can build complex workflows. However, Omnisend has an edge since it allows adding multiple channels to a workflow. Omnisend also lets you customize analytics, but you only get up to 18 months of historical data. Not terrible, but older data can sometimes be valuable.

This is excellent for ecommerce businesses because you can reach out to customers via multiple channels to elicit a response. For example, you can email a customer right after they abandon the cart. Send them an SMS later the same day, and follow up with an offer via a push notification.

Why automate marketing tasks?

You can’t send 5,000 messages manually — whether it’s via email or SMS. That’s why you need a marketing automation tool. It allows you to connect with your customers and leads at scale, helping you grow your business.

Marketing Automation Report 2021 reveals that 49% of participants cite time savings as a major benefit of automating repetitive tasks. You can spend the time you save with automation on strategic tasks or tasks that need a human touch — such as brand strategy, blog content, and video production.

Automation also helps collect information efficiently. A marketing automation tool centralizes data from all marketing channels, giving you a better sense of where your customers are and how often they engage with your brand. This information helps you draw a roadmap for achieving business goals.

For example, you can personalize your messaging based on customer data, campaign engagement, and customer behavior to increase average order value and improve other financial metrics.

Marketing automation tools like Omnisend and Klaviyo make it easier to market to shoppers where they are, at the right time. They provide centralized access to marketing platforms so you can control campaigns for email, SMS, and other channels from a single dashboard.
