Our customers' return on spend is core to Zembula's long term success

Zembula’s Dimensions™ delivers on the promise of daily email personalization.

Marketers have known the potential for years, but until now, it hasn’t been possible to efficiently deliver an automated personalization program in the daily retail marketing email.

Zembula Dimensions provides the first solution to fully automate daily email personalization and deliver over an 11x return on spend without changing your daily workflow.

Below is the week-over-week graph of Zembula’s total revenue compared to the click-attributed revenue generated by our customers each week with Zembula-powered content.

As our Dimensions program grows, we continue to learn and expand the use cases we power for customers. The secret to performance has been the extensive long-tail of personalized use cases.

Currently, our customers average $16 in revenue for every $1 they spend with Zembula YTD in 2024.

The rapid customer adoption and use case expansion of Zembula Dimensions have continued to improve the efficiency of every dollar spent with Zembula.

We want to be the most efficient next dollar you can spend in marketing.

Click attribution is a great way to monitor daily performance and provides creative-level insights. But it’s not the only method we use for monitoring the performance we deliver to our customers. We also include longitudinal testing, which is the gold standard.

Check out how we track performance over time with these two tests.

The four-week longitudinal audience test

The first method is a longitudinal audience test over four weeks (sometimes, we extend this time period). We split the audience 50/50; half will see Dimensions, and the other half will see an email without Dimensions™.

Each audience is assigned to a group as an email is opened. This helps reduce noise and has the added benefit of attracting new subscribers as they begin to engage.

During the test, we maintained the audiences and tracked the revenue and transactions from each group. At the end of testing, we checked that 95% statistical significance had been achieved and compared the revenue and transactions from each group.

The longitudinal audience test results regarding the revenue lift Zembula Dimensions drives are extremely reliable. We also have the audience data that we can provide to customers so they can do their own analysis and verify the results.

Seven-day click-based revenue attribution

We’ve found click-based revenue attribution on just the content Zembula powers is a good indicator of program performance.

We’ve seen the click attribution on Dimensions track pretty closely to the revenue lift we see in our longitudinal audience-based testing.

Our methodology is a seven-day click-based attribution on the Zembula Dimensions banners displayed across our customers’ email program. This click-based attribution provides our customers with valuable creative-level insights on content performance, leading to improvements that have greatly boosted results over time.

We’re always looking at new ways to track and analyze content performance so that our customers can continuously improve their marketing programs.
