"How much does it bring in?" That's THE question your executives ask you when you ask them to invest in Klaviyo. And you know what? It's totally legitimate. In a world where every euro counts, measuring the ROI of your email marketing is no longer optional, it's vital.
But here's the problem: calculating ROI with Klaviyo isn't as simple as they say. Between scattered data, conflicting attribution models, and metrics that don't tell the whole story... How do you make sense of it all?
In this article, we're going to break down together how to precisely measure Klaviyo's profitability, with concrete figures and methods that really work.
Why email marketing ROI is crucial (and misleading)
The dream figures
Email marketing is the king channel in terms of ROI. The statistics are impressive: €36 to €38 in revenue for every euro invested on average, which means an ROI of 3600% to 3800%. Some sectors do even better:
- E-commerce: €45 for €1 invested
- Travel and tourism: €53 for €1 invested
- Software and technology: €40 for €1 invested
And Klaviyo? Brands that switch to Klaviyo see an average revenue increase of 46% in two years, with an average ROI of €68 for every euro spent.
But beware of misleading averages
These figures can be misleading. They hide huge disparities between companies. Some literally explode their results, while others struggle to achieve profitability.
Your ROI depends on:
- Your industry
- The quality of your list
- Your automation strategy
- Your ability to segment
- The relevance of your content
How to calculate Klaviyo ROI: the basic formula
The simple mathematical formula
ROI = (Revenue generated by email – Email marketing costs) / Email marketing costs
Concrete example:
- Revenue generated: €50,000
- Klaviyo costs: €2,000
- ROI = (50,000 – 2,000) / 2,000 = 24, or 2400%
But it's more complicated than that…
This simple formula hides several difficulties:
- Defining email-attributable revenue How to isolate sales due to your emails? A customer might see your Facebook ad, receive your newsletter, then buy via Google. Who gets the credit?
- Calculating all costs Costs include: Klaviyo subscription, team time, additional tools, content creation, training...
- Taking into account temporality Especially in B2B, the sales cycle can last for months. A lead generated in March might buy in June.

The 5 attribution models for measuring your ROI
1. Last-click attribution
All credit goes to the last touchpoint before purchase. Simple, but reductive.
Advantages:Easy to understand and implement
Disadvantages:Ignores all nurturing work
2. First-click attribution
All credit goes to the first touchpoint (often the ad that brought the visitor).
Advantages:Recognizes the importance of acquisition
Disadvantages:Minimizes the role of conversion
3. Linear attribution
Each touchpoint receives equal credit. If 10 interactions lead to a €200 purchase, each interaction receives €20 of credit.
Advantages:More equitable
Disadvantages:Not all touchpoints are equal
4. Position-based attribution
You assign different weights based on the importance of each stage (e.g., 40% first click, 40% last click, 20% distributed among others).
5. Time decay attribution
The closer to the sale, the more credit the stages get. The idea: the prospect gradually moves closer to purchase.
Which model to choose?
For e-commerce with many automations:Time decay or last-click attribution
For a multi-channel strategy:Linear attribution
To measure the pure effectiveness of Klaviyo:Last-click on emails

Levers to optimize your Klaviyo ROI
1. Maximize the value of automations

- Abandoned cart: €3.65 on average, €28.89 for the top 10%
- Post-purchase: Reactivation and cross-sell
- Win-back: Re-engaging inactive users
2. Advanced segmentation
Precise segmentation can double your ROI. Segment by:
- Purchase behavior (frequency, amount)
- Lifecycle stage (prospect, customer, VIP)
- Engagement (highly active, moderately active, dormant)
- Geography and demographics
Concrete example:A cosmetics brand segments by skin type mentioned in a quiz. Result: +85% click-through rate, +127% revenue per email.
3. Systematic A/B testing
Companies that regularly A/B test have an ROI of 4200% versus 2300% for those that never do.
Elements to test:
- Email subject lines (impact: +20-50% opens)
- CTAs and colors (+15-30% clicks)
- Send times (+10-25% engagement)
- Send frequency (find the sweet spot)
4. Data optimization and cleanup
Regularly clean your list by removing hard bounces and creating re-engagement flows for inactive users.
Monthly action plan:
- Automatically remove hard bounces
- Identify inactive users 90+ days
- Launch a win-back campaign
- Remove non-responders after 6 months
5. Dynamic personalization
Use behavioral data to personalize:
- Product recommendations based on history
- Content adapted to the customer journey stage
- Personalized offers based on customer value
- Messages adapted to the preferred channel (email vs SMS)
Avoiding ROI calculation pitfalls
Pitfall #1: Calculating too early
Especially in B2B, wait until the end of the quarter or semester to get a complete picture, as the sales cycle can be long.
Pitfall #2: Ignoring indirect conversions
Not all emails generate direct sales. Also consider:
- Content downloads
- Webinar registrations
- Demo requests
- Website traffic
Calculate a "Return on Objective" (ROO) for these actions that prepare the sale.
Pitfall #3: Comparing the incomparable
Do not compare:
- Campaigns vs. automations
- B2B vs. B2C
- Acquisition vs. retention
- New customers vs. existing customers
Pitfall #4: Forgetting customer lifetime value
If you know the Customer Lifetime Value, attribute this total value to the conversion rather than just the first purchase. This is more accurate for measuring long-term impact.
