Quick summary
This post explains how automated email flows, such as abandoned cart, welcome series, post-purchase, and win-back sequences, outperform broadcast campaigns and account for 25 to 40 percent of revenue in high-performing Shopify stores. It covers which email platforms integrate best with Shopify, with Klaviyo recommended as the standard choice, and walks through how to set up and optimise each core flow. Benchmarks, timing guidance, and split-testing advice are included throughout.
You are sending the occasional promotional email to your full list and wondering why email only accounts for a fraction of your revenue. The stores generating 25 to 40 percent of their total revenue from email are not sending more campaigns. They are running automated flows that trigger at exactly the right moment, delivering the right message when a customer is most likely to act.
What are email flows and why do they outperform campaigns?
Email flows (also called automations or sequences) are pre-built email sequences triggered by customer behaviour. Someone abandons their cart, and they receive a reminder. A customer makes their first purchase, and a welcome series begins. A loyal buyer goes quiet for 60 days, and a win-back email lands.
Flows outperform campaigns because they are contextual. A campaign goes to everyone at the same time. A flow reaches a specific person at a specific moment based on what they just did. According to Klaviyo's benchmark data, automated flows generate 29 times more revenue per recipient than campaign emails.
The other advantage is that flows run on autopilot once set up. You build them once, optimise over time, and they generate revenue around the clock.

If you are just starting out and your list is small, Shopify Email handles the basics at no cost. But you will outgrow it quickly once you want proper flow logic, A/B testing, and advanced segmentation.
What are the essential Shopify email flows to set up first?
Build these five flows in order of revenue impact. Each one addresses a specific stage of the customer journey.
1. Abandoned cart flow
This is the single highest-revenue automation for most Shopify stores. On average, 70 percent of online shopping carts are abandoned. An abandoned cart flow recovers 5 to 15 percent of those lost sales.
Recommended sequence:
- Email 1 (1 hour after abandonment): Reminder with cart contents, product images, and a direct link back to checkout. No discount yet.
- Email 2 (24 hours after abandonment): Address common objections. Include social proof, shipping info, and returns policy.
- Email 3 (48 hours after abandonment): Final nudge. Consider offering a small incentive (free shipping or 5 to 10 percent off) if margins allow.
Key tips:
- Include product images and prices in every email. Customers forget what they were looking at.
- Use a clear, single call-to-action button: "Complete your order."
- Do not lead with a discount in email one. Many abandoned carts convert with a simple reminder.
2. Welcome series
First impressions set the tone for the entire customer relationship. A welcome series introduces your brand, builds trust, and nudges the subscriber toward their first purchase. Welcome emails have an average open rate of 50 percent, which is double the rate of standard campaigns.
Recommended sequence:
- Email 1 (immediately on sign-up): Thank them, deliver any promised incentive (discount code), and introduce your brand story in two to three sentences.
- Email 2 (day 2): Highlight best sellers or curated collections. Help new subscribers find what is relevant to them.
- Email 3 (day 4): Share social proof: customer reviews, press mentions, or user-generated content.
- Email 4 (day 7): If they have not purchased, remind them of the welcome offer with urgency ("Your 10% off expires in 48 hours").
3. Post-purchase flow
The sale is not the end of the relationship. It is the beginning. Post-purchase emails drive repeat purchases, reduce buyer's remorse, and turn one-time buyers into loyal customers.
Recommended sequence:
- Email 1 (immediately after purchase): Order confirmation with expected delivery timeline and a thank you message.
- Email 2 (3 days after delivery): Ask how they are finding the product. Include care tips or usage suggestions.
- Email 3 (7 days after delivery): Request a product review. Include a direct link to leave a review on the product page.
- Email 4 (21 days after purchase): Cross-sell complementary products based on what they bought.
The review request email is particularly valuable. Stores that automate review collection see three to five times more reviews than those relying on customers to leave feedback unprompted.
4. Win-back flow
Customers go quiet. It happens. A win-back flow re-engages lapsed customers before they forget about you entirely. It costs far less to reactivate an existing customer than to acquire a new one.
Recommended sequence:
- Email 1 (60 days since last purchase): "We miss you" message with new arrivals or best sellers since their last order.
- Email 2 (75 days): Offer an incentive to return. A percentage discount or free shipping works well.
- Email 3 (90 days): Final attempt. Stronger offer or a "last chance" message before you reduce email frequency to this contact.
If a customer does not engage after three win-back emails, move them to a suppressed segment. Continuing to email unengaged contacts hurts your deliverability.
5. Browse abandonment flow
This catches customers who viewed products but did not add anything to their cart. It is higher up the funnel than cart abandonment, so conversion rates are lower, but the volume of triggers is much higher.
Recommended sequence:
- Email 1 (2 hours after browsing): "Still thinking about [product name]?" with an image and link.
- Email 2 (24 hours): Show similar products or the same product with reviews and social proof.
Keep this flow to two emails maximum. More than that feels intrusive for someone who only viewed a product page.
How do you segment your Shopify email list effectively?
Sending the same email to everyone wastes your best-performing content on people who do not care about it. Segmentation ensures the right message reaches the right customer.
Essential segments to create:
| Segment | Definition | Use For |
|---|---|---|
| First-time buyers | Purchased once, never returned | Post-purchase nurture, second purchase incentive |
| Repeat customers | Two or more purchases | Loyalty programme promotion, VIP offers |
| High spenders | Top 20% by lifetime value | Exclusive early access, premium product launches |
| Lapsed customers | No purchase in 60 to 90 days | Win-back flows |
| Engaged non-buyers | Opens emails but has not purchased | Targeted offers, social proof content |
| VIPs | High spend and high frequency | Personal outreach, exclusive previews |
Klaviyo builds most of these segments automatically from Shopify data. You set the conditions once, and the segments update dynamically as customer behaviour changes.
What metrics should you track for email flow performance?
| Metric | Good Benchmark | What It Tells You |
|---|---|---|
| Flow revenue per recipient | £2 to £5 for cart abandonment | Revenue efficiency of each flow |
| Open rate | 40 to 60% for flows | Subject line and sender reputation |
| Click rate | 5 to 10% for flows | Content relevance and CTA effectiveness |
| Conversion rate | 3 to 8% for cart abandonment | Overall flow effectiveness |
| Unsubscribe rate | Below 0.3% per email | Content quality and frequency balance |
| List growth rate | 5 to 10% per month | Sign-up form and lead magnet effectiveness |
Review flow performance monthly. The most impactful optimisation is usually A/B testing subject lines, which can swing open rates by 10 to 20 percent.

Which email flow should I set up first on Shopify?
Start with your abandoned cart flow. It targets customers who have already shown purchase intent, making it the highest-converting automation available. A three-email sequence over 48 hours, without a discount in the first email, typically recovers 5 to 15 percent of abandoned carts.

Klaviyo's native Shopify integration syncs purchase history, browsing behaviour, and product data in real time, which is what makes flows genuinely personalised and commercially effective.
How often should I review and update my email flows?
Review flow performance monthly. Focus on open rate, click rate, and conversion rate for each email in the sequence. The most impactful single change is usually A/B testing subject lines, which can shift open rates by 10 to 20 percent. Refresh email copy and imagery quarterly to avoid creative fatigue.
