If you’re spending thousands every month on Meta and Google ads but barely investing in email, you’re essentially pouring water into a leaky bucket. Paid traffic is expensive, competitive, and entirely out of your control — a single algorithm update can wipe out your results overnight. Klaviyo is the tool that seals the leaks.
Klaviyo is an email and SMS marketing platform built specifically for ecommerce. Unlike generic email tools, it connects directly to your store — whether you’re on Shopify, WooCommerce, BigCommerce, or Magento — and turns your customer data into personalised, automated revenue.
Abandoned cart flows are the most well-known, but most stores set them up once and forget them. A properly optimised abandoned cart sequence — timed correctly, personalised to the product left behind, with smart incentive logic — typically recovers 5–15% of abandoned sessions. That’s revenue that would simply disappear without it.
Browse abandonment flows take things a step further. Someone looks at a product page but doesn’t add to cart? They’re still a warm prospect. A well-crafted browse abandonment email, sent within the right window, brings them back before your competitors do.
Post-purchase flows are arguably the most underused sequence in ecommerce. The period immediately after a customer buys is when trust and excitement are at their peak. It’s the perfect moment to cross-sell, encourage a review, introduce your loyalty programme, or simply build the kind of relationship that turns a one-time buyer into a loyal customer worth five times more over their lifetime.
Win-back flows target customers who haven’t bought in 90, 120, or 180 days. Rather than letting them quietly churn, Klaviyo lets you create intelligent re-engagement sequences that acknowledge the gap and offer a compelling reason to return.
Where Klaviyo truly separates itself from platforms like Mailchimp or Omnisend is its segmentation depth. You can build audiences based on predicted lifetime value, purchase frequency, product categories bought, average order value, engagement level, geographic location, and dozens of other data points. This means your campaigns land with relevance rather than feeling like spam.
The platform also integrates SMS seamlessly alongside email, letting you build coordinated multi-channel flows that reach customers wherever they prefer to engage.
For a mid-sized ecommerce brand turning over £500k–£2m per year, a fully built-out Klaviyo setup typically generates between 20–40% of total revenue from email and SMS alone. That’s revenue driven by owned channels, not paid ones.
The brands achieving this aren’t doing anything mysterious. They have the right flows active, they’re testing their messaging consistently, their lists are healthy and growing, and their segmentation ensures the right message reaches the right person at the right time.
If your email channel is currently sitting below 15% of revenue, there’s work to do — and it’s very worth doing. Getting Klaviyo set up properly isn’t just about clicking “activate” on a few default flows. Strategy, copywriting, design, segmentation logic, and ongoing optimisation all play a role.
