Why Email Marketing Is the Highest-ROI Channel for Shopify Stores
For every £1 spent on email marketing, the average ecommerce store earns back £36–£42. No other digital channel — not paid ads, not social media, not SEO — consistently delivers that return. And unlike Meta or Google, you own your email list. Algorithm changes don’t wipe out years of list-building overnight.
Yet most Shopify store owners treat email as an afterthought — sending the occasional newsletter when they remember, with no flows, no segmentation, and no strategy. This guide changes that. We’ll build a complete email marketing foundation from scratch, even if you’ve never sent a single campaign before.
Step 1: Choose the Right Email Platform for Shopify
Shopify Email (the built-in tool) is fine for getting started, but it lacks the automation depth serious stores need. The three platforms worth considering are:
- Klaviyo — the industry gold standard for Shopify. Deep native integration, powerful flows, predictive analytics, and SMS built-in. Best for stores doing £5k+/month.
- Omnisend — strong automation, more affordable than Klaviyo, good for stores just scaling up. Includes email, SMS, and push in one tool.
- Mailchimp — familiar interface but weaker Shopify sync than Klaviyo. Fine for early-stage stores under 1,000 subscribers.
For most growing Shopify stores, Klaviyo is the right choice. Its Shopify integration syncs every order, browse event, and customer property in real time — making hyper-targeted automations possible.
Step 2: Build Your List — The Right Way
A healthy email list grows from multiple capture points, not just a footer form that nobody sees. Set up all of these:
- Popup with offer — 10–15% discount or free shipping for first-time subscribers. Trigger after 5 seconds or 30% scroll, not immediately on page load.
- Embedded form — in the footer and on the About page for visitors who scroll past the popup.
- Checkout opt-in — pre-ticked “Sign up for offers” checkbox at checkout captures buyers who haven’t subscribed yet.
- Post-purchase landing page — offer something extra (exclusive content, a loyalty tier unlock) in exchange for a confirmed opt-in.
- Quiz or tool — “Find your perfect [product]” quizzes capture emails at a 30–40% rate, higher than most popups.
Step 3: The 5 Essential Email Flows Every Shopify Store Needs
Flows (also called automations or sequences) are triggered emails that go out automatically based on subscriber behaviour. They run 24/7 without you touching them and typically account for 30–50% of total email revenue.
1. Welcome Flow (5–7 emails)
Sent to new subscribers who haven’t purchased yet. Structure: brand story → social proof → best-sellers → overcome objections → urgency/offer expiry. This single flow often generates 15–25% of all email revenue for newer stores.
2. Abandoned Cart Flow (3 emails)
Sent when someone adds to cart but doesn’t complete checkout. Email 1 at 1 hour (reminder, no discount). Email 2 at 24 hours (add social proof). Email 3 at 48 hours (small incentive if they haven’t purchased). Average recovery rate: 5–15% of abandoned carts.
3. Browse Abandonment Flow (2 emails)
Sent when a subscribed visitor views a product but doesn’t add to cart. Softer than cart abandonment — just a gentle nudge showing what they were looking at plus similar products.
4. Post-Purchase Flow (4–6 emails)
Starts after first purchase. Includes: order confirmation, shipping update, delivery confirmation with usage tips, review request, cross-sell recommendations, and a loyalty/referral invitation. Turns one-time buyers into repeat customers.
5. Win-Back Flow (3 emails)
Sent to subscribers who haven’t opened an email or purchased in 90–180 days. Last attempt to re-engage before suppressing to protect deliverability. Typically includes a “we miss you” message and a time-limited offer.
Step 4: Email Campaign Calendar
Flows handle the automated side. Campaigns are your regular broadcast emails to your full list or segments. A sustainable cadence for most stores:
- 1–2 emails per week to engaged subscribers (opened in last 90 days)
- 1 email per week maximum to less-engaged segments
- Campaign types to rotate: product launches, educational content, customer stories, seasonal promotions, behind-the-scenes, curated collections
Never email your full unengaged list — it tanks your deliverability and trains ISPs to put you in spam.
Step 5: Segmentation Basics
Send the right email to the right person. Start with these four core segments:
- VIPs — top 10–20% of customers by total spend. Get early access, exclusive offers, and personal touches.
- One-time buyers — purchased once, haven’t returned. Target with cross-sell and “what to try next” campaigns.
- Active subscribers, never purchased — still in consideration phase. Use social proof and objection-handling content.
- Lapsed customers — bought 6+ months ago, haven’t returned. Win-back campaigns or suppression.
Key Metrics to Track
- Open rate — benchmark 35–45% for flows, 20–35% for campaigns
- Click rate — 2–5% is solid; under 1% means your content or CTA needs work
- Revenue per recipient (RPR) — the truest measure of email effectiveness
- List growth rate — are you adding more subscribers than you’re losing?
- Deliverability rate — aim for 98%+ inbox placement
