One way of achieving this is through the support of some sophisticated email marketing automation software. Such a tool can ensure every email marketing campaign is engaging for current and potential customers alike, using a variety of advanced features and data sources to do so.

Create targeted audience segments based on product purchases, discount code use, demographic data and other key metrics. Number of segments allowed are limited based on subscription plan.

Ease of use and dashboard

Omnisend is ideal if you are a novice email marketer and are looking for beginner-friendly automation, rather than advanced features and subscriber segmentation. The simple backend design and easy-to-use dashboard mean you can set up and implement your first campaign and welcome series quickly.

Klaviyo, on the other hand, does have a more advanced feature set and this comes with a comparatively steeper learning curve. This is easy enough to overcome, however, and you will find that the intuitive tool has everything a growing ecommerce store could need from an email marketing platform including built-in templates and automation workflows to help your first campaign get up and running in no time.

The Klaviyo dashboard is clean and clear, displaying key information relating to analytics, lists and segments, campaigns and automation flows, as well as total revenue from the past seven, 30, 90 or 365 days.

Email marketing features

Email marketing is at its best when it has a wide range of features for companies to access. For example, segmentation should be one of the key aspects of any marketing campaign, ensuring that each email reaches the right customer.

Klaviyo does not limit the number of segments you can create or the criteria and data used to build them. Omnisend do offer segmentation, but the number of segments you can create depends on your subscription plan and the capabilities are not as advanced as Klaviyo’s.

The same is true for A/B testing; with Omnisend this is limited to sender name and subject lines only, whereas Klaviyo offer this as well as email send time, content and more.

Automated workflow capabilities are another important factor to look for in an email marketing platform. For example, you can start a welcome series that is triggered when a customer creates an account with your online store or places their first order. Klaviyo and Omnisend both provide this type of automation, but Klaviyo has a more extensive feature set than Omnisend. This includes automated emails about product restocks, price drops and personalised discount codes to encourage customers to complete a cart abandonment.

Ecommerce viability

In terms of the viability of each piece of software for ecommerce purposes, both are strong platforms in their own right that specialise in different areas of the industry.

Klaviyo is incredibly sophisticated marketing software that allows users to tailor every email campaign in an intelligent and meaningful way, informed by historical and recent data from a number of sources. This is ideal for ecommerce businesses in need of a data-driven approach to growth and boosting sales.

Because Omnisend is simpler to use initially, it is better suited to email marketing beginners and businesses with a small budget that can’t currently accommodate the time or energy needed for training and knowledge development. It is also more appropriate for marketers working in other online industries, as Klaviyo is designed specifically for ecommerce.
