Why Email Marketing Still Matters for Ecommerce Brands
Many ecommerce businesses install Klaviyo expecting email marketing to become a strong revenue channel.
But in reality, email often ends up underperforming.
Brands set up a basic welcome email, send the occasional campaign, and then move on to focusing on ads, product launches, and social media.
The problem is that email marketing only becomes powerful when it’s structured properly.
When lifecycle flows, segmentation, and campaign strategy work together, email becomes one of the most predictable revenue channels in an ecommerce business.
Below are three real examples of what email marketing generated for different ecommerce brands using Klaviyo.
Example 1: $84,554 in Email Revenue in One Month
One ecommerce client generated $84,554 in revenue from email in a single month.
Most of this revenue came from automated flows rather than a single promotional campaign.
These flows included:
- A welcome flow converting new subscribers
- Abandoned cart emails recovering lost purchases
- Post-purchase emails encouraging repeat orders
- Campaign sends to engaged subscribers
When these systems are built properly, email runs continuously in the background of the business.
Instead of relying solely on advertising, brands start generating revenue from subscribers who have already shown interest in their products.
This is where Klaviyo becomes significantly more powerful than basic email platforms.
Example 2: 49% of Total Store Revenue From Email
In another ecommerce brand we worked with, 49% of the store’s total revenue came directly from email marketing.
This type of performance typically happens when a brand has a strong lifecycle email strategy in place.
Instead of sending the same campaigns to every subscriber, emails are triggered based on behaviour.
For example:
- New subscribers receive a welcome sequence
- Browsers receive product reminder emails
- Customers receive post-purchase follow-ups
- Inactive subscribers receive winback emails
This behaviour-based automation allows Klaviyo to deliver highly relevant emails at the right stage of the customer journey.
As a result, engagement increases and email becomes a major driver of repeat purchases.
Example 3: 102% Growth in Email Revenue
Another ecommerce brand saw email-generated revenue increase by 102% after restructuring their Klaviyo system.
The brand already had email marketing in place, but the setup lacked structure.
Some flows existed, but they weren’t optimised. Campaigns were being sent inconsistently, and segmentation was limited.
After improving the system, results came from several areas:
- Higher-converting welcome flows
- Additional abandoned cart reminders
- Better segmentation for campaigns
- A stronger post-purchase strategy
None of these changes were dramatic on their own.
But together they created a system where email started performing far more consistently.
This is a common pattern in ecommerce email marketing, small improvements across multiple lifecycle flows can significantly increase revenue over time.
What High-Performing Klaviyo Accounts Have in Common
Although these ecommerce brands were in different industries, their Klaviyo accounts shared several important characteristics.
They all had a structured customer lifecycle email system, including:
- Welcome flows for new subscribers
- Abandoned cart recovery sequences
- Post-purchase follow-up emails
- Winback campaigns for inactive customers
They also used segmentation to send more relevant campaigns rather than broadcasting the same message to every subscriber.
When these systems work together, email becomes one of the most reliable revenue channels in an ecommerce business.
The Most Common Klaviyo Problem We See
When reviewing ecommerce Klaviyo accounts, one issue appears repeatedly.
Brands rely heavily on campaign emails, but their automation flows are underdeveloped.
Campaigns are useful, but flows are what create consistent revenue.
Flows run continuously in the background of the business:
- converting new subscribers
- recovering abandoned carts
- encouraging repeat purchases
- re-engaging inactive customers
Without these systems, email marketing becomes inconsistent and underperforms its potential.
When Email Becomes a Reliable Revenue Channel
When Klaviyo is implemented strategically, email marketing becomes a powerful retention channel.
Instead of relying entirely on paid traffic to generate sales, brands start generating revenue from their existing subscribers and customers.
Welcome flows convert new visitors.
Abandoned cart emails recover lost orders.
Post-purchase emails drive repeat purchases.
Winback flows bring customers back who might otherwise disappear.
Together, these systems create a lifecycle email strategy that generates revenue every day.
Improving Your Klaviyo Email Marketing System
If your ecommerce brand already uses Klaviyo but email marketing isn’t generating consistent results yet, the issue usually isn’t the platform itself.
More often, it’s the structure behind it.
Many brands have the right tools but haven’t yet built the lifecycle systems that allow those tools to perform properly.

FAQ
How much revenue can email marketing generate for ecommerce brands?
Email marketing can generate a significant percentage of ecommerce revenue when implemented properly. Many brands see email contribute between 20% and 40% of total store revenue, particularly when lifecycle flows such as welcome emails, abandoned cart recovery, and post-purchase emails are optimised.
Why do many Klaviyo accounts underperform?
Many Klaviyo accounts rely primarily on promotional campaigns instead of lifecycle automation. Without flows like welcome sequences, abandoned cart emails, post-purchase follow-ups, and winback campaigns, email marketing often underperforms its potential.
What are the most important Klaviyo flows for ecommerce brands?
Most high-performing ecommerce email systems include four key flows:
- Welcome flow for new subscribers
• Abandoned cart recovery emails
• Post-purchase follow-up emails
• Winback emails for inactive customers
These flows create a lifecycle email strategy that generates revenue continuously.
Is Klaviyo worth it for ecommerce email marketing?
Klaviyo is widely used by ecommerce brands because it integrates directly with platforms like Shopify and provides strong automation, segmentation, and analytics features designed for online stores.
