Abandoned Cart Email Strategy & Ecommerce Email Automation That Actually Recovers Revenue
The average ecommerce store loses 70% of its carts to abandonment. Most of that revenue is recoverable—if you have the right flows in place. And abandoned carts are just one piece of the puzzle. The brands seeing 30–40% of revenue from email have an entire automation system working behind the scenes.
Flypost builds Klaviyo email automation for ecommerce brands—abandoned cart recovery, welcome series, post-purchase flows, browse abandonment, winbacks, and more. Every flow is built with revenue as the KPI, not open rates.

The Klaviyo Flows That Drive Ecommerce Revenue
There are dozens of possible automations in Klaviyo. These are the ones that move the needle for ecommerce brands, in order of revenue impact:
1. Abandoned Cart Email Strategy
This is usually the single highest-revenue flow in any Klaviyo account. When a shopper adds to cart and leaves without buying, you have a narrow window to bring them back before they forget or buy elsewhere.
A strong abandoned cart email strategy isn't just one reminder email. We build multi-step sequences with strategic timing, dynamic product content, social proof, urgency triggers, and coordinated SMS follow-ups. The goal is to recover as much revenue as possible without training customers to wait for discounts.
For Lofi Girl, we rebuilt their abandoned cart flow and drove a 3.2x increase in cart recovery revenue. For Linus Bikes, the optimized cart flow generated $67K in recovered revenue.
2. Welcome Series Email Flow
Your welcome series sets the tone for the entire customer relationship. It's also the flow with the highest open rates you'll ever see—subscribers are paying attention right now, so make it count.
We build welcome flows that go beyond "thanks for subscribing." The best welcome series for ecommerce brands introduce the brand story, highlight bestsellers, address common objections, and create a clear path to first purchase—all within 3–5 emails over the first week.
Smart branching matters here. Someone who buys on email one shouldn't get the same sequence as someone who hasn't clicked anything. We use Klaviyo's conditional splits to route subscribers based on engagement and purchase behavior, so every message is relevant.
3. Browse Abandonment
Browse abandonment catches the shoppers who looked at specific products but didn't add to cart. It's a higher-funnel flow than cart abandonment, so the messaging needs to be different—less urgency, more inspiration and social proof.
We trigger these flows in Klaviyo based on Shopify product views, with dynamic content that shows the exact products they browsed plus related recommendations. Timing is key: too soon feels pushy, too late and they've forgotten.
4. Post-Purchase Sequences
The sale isn't the end of the journey—it's the beginning of retention. Post-purchase flows handle order confirmation, shipping updates, product education, review requests, and cross-sell recommendations.
We build these sequences to match the product's use cycle. A skincare brand needs different timing than a bike brand. The goal: reduce buyer's remorse, increase product satisfaction, and drive the second purchase as fast as possible.
5. Winback Campaigns
Customers go dormant. That's normal. What matters is having a system to re-engage them before they churn for good. Winback flows target customers who haven't purchased in a defined window (typically 60–120 days depending on your product cycle).
We layer winback flows with product recommendations based on past purchase history, exclusive offers for returning customers, and SMS touchpoints for customers who've gone cold on email.
6. VIP & Loyalty Flows
Your top 10% of customers drive a disproportionate amount of revenue. They deserve a different experience. We build VIP segments in Klaviyo based on lifetime spend and purchase frequency, then create exclusive flows—early access to drops, private discounts, loyalty milestones, and personal touches that keep your best customers buying.
What Automation Results Look Like
These aren't hypothetical benchmarks. Lofi Girl had zero automation before working with Flypost—we built their entire Klaviyo program from scratch, including every flow listed above. Linus Bikes had basic flows that were underperforming—we rebuilt and optimized them, resulting in 42% of total revenue attributed to Klaviyo. See the full details in our case studies.

We don't use templates from a playbook and call it done. Every automation we build is customized to your brand, products, and customer behavior. Here's the process:
Step 1: Audit Your Current Flows
We map everything that's live in Klaviyo—triggers, timing, content, performance data. We identify what's working, what's broken, and what's missing entirely. Most brands have 2–3 flows running. They need 6–8 to capture the full revenue opportunity.
Step 2: Design the Automation Blueprint
We create a flow-by-flow plan with defined goals, email count, timing logic, conditional splits, SMS touchpoints, and KPI targets. You approve the blueprint before we build anything.
Step 3: Build, QA, Launch
We build every flow in Klaviyo—writing copy, designing templates, configuring triggers, setting up A/B tests, and running deliverability checks. Every flow is QA'd across devices and email clients before going live.
Step 4: Optimize Monthly
Flows aren't "set and forget." We review performance weekly, run A/B tests on subject lines, timing, and content, and make data-driven refinements every month. The brands that see compounding results are the ones that keep optimizing.
Why We Build on Klaviyo
We're a certified Klaviyo agency partner because Klaviyo is the best email automation platform for ecommerce. It's not even close for Shopify brands.
Klaviyo's deep Shopify integration means we can trigger flows based on real purchase data, product views, cart activity, and customer segments that update in real time. Advanced features like predictive analytics, conditional splits, and dynamic product feeds let us build automation that's genuinely personalized—not just "Hi {first_name}" personalization.
If you're currently on Mailchimp, Omnisend, or another platform that wasn't built for ecommerce automation, migrating to Klaviyo is often the single biggest unlock. We handle Klaviyo migrations end-to-end. Read our breakdown of Klaviyo vs Mailchimp for ecommerce if you're weighing the switch.

SMS + Email Automation: Better Together
The highest-performing ecommerce automation stacks combine email and SMS. We coordinate both channels through Klaviyo and Postscript so they work as a system, not in silos.
For abandoned carts, that means an email at 1 hour and an SMS at 4 hours—or vice versa depending on what the data shows. For welcome series, it means a text with a discount code arriving right after the first email. For winbacks, it means reaching customers on the channel they're most likely to engage with.
The key is coordination. We manage send frequency across both channels so customers get the right number of touchpoints without feeling spammed. Every SMS automation we build is TCPA-compliant with proper opt-in flows and easy unsubscribe.
Automation Only Works if Emails Reach the Inbox
The most sophisticated flows in the world are worthless if they're landing in spam. Deliverability is baked into how we build automation—proper sending domain setup, DMARC/DKIM/SPF authentication, list hygiene, sunset flows for unengaged subscribers, and ongoing monitoring.
We've seen brands come to us with 15–20% of emails going to spam without knowing it. Fixing authentication and sender reputation is often a quick win that immediately improves flow performance across the board.

Frequently Asked Questions
How many flows does my ecommerce brand need?
At minimum, you need an abandoned cart flow, welcome series, and post-purchase sequence. A fully built-out Klaviyo program typically has 6–10 active flows including browse abandonment, winback, VIP, replenishment, and sunset flows. We prioritize by revenue impact so the highest-value flows go live first.
What's a good abandoned cart recovery rate?
A well-optimized abandoned cart flow should recover 5–15% of abandoned carts, depending on your product and price point. If you're below 3%, there's significant room for improvement. High-AOV products like bikes and jewelry tend to have lower recovery rates but higher revenue per recovery.
How long does it take to build out all my flows?
Core flows (cart, welcome, post-purchase) can be live within the first 2–3 weeks. A full automation buildout with 6–8 flows, A/B tests, and SMS integration typically takes 6–8 weeks. We prioritize by revenue impact so you start seeing results from day one.
Should I offer discounts in my abandoned cart emails?
Not in the first email. Leading with a discount trains customers to abandon carts on purpose. We structure cart recovery sequences to start with reminders and social proof, then escalate to incentives only in later emails for customers who haven't converted. The goal is to recover revenue without eroding margins.
Can you fix my existing Klaviyo flows or do you rebuild from scratch?
It depends on what you have. If the flow architecture is solid but the content and timing need work, we optimize. If the flows are fundamentally broken or missing key logic, we rebuild. Either way, we audit first and recommend the approach that gets results fastest.
What's the difference between flows and campaigns?
Flows are automated sequences triggered by customer behavior (added to cart, made a purchase, signed up). They run 24/7 without manual effort. Campaigns are one-time sends you schedule for specific dates—promotions, product launches, content drops. You need both. Flows build the foundation; campaigns drive revenue spikes. We handle both as part of our email marketing services.
