Email marketing consistently delivers the highest return on investment of any digital channel for e-commerce. For Shopify stores, it's not just an option — it's the most reliable way to turn one-time buyers into loyal customers.
This guide covers everything you need to know: why email marketing matters for Shopify, which platform to choose, the automations you should set up on day one, and how to track whether any of it is actually working.
Why Email Marketing Matters for Shopify Stores
The average e-commerce store sees 2–4% of visitors convert on any given session. That means 96–98% of people who land on your store leave without buying. Email marketing is your best tool for capturing those visitors and converting them over time.
A few numbers that put this in context:
- $42 return for every $1 spent — Email marketing's average ROI consistently outperforms paid social and search ads.
- Owned audience — Unlike Facebook or Instagram followers, your email list belongs to you. Algorithm changes don't affect your reach.
- Purchase intent — People who subscribe to your list are signaling interest. They're not passive scrollers; they've actively opted in.
For Shopify specifically, email integrates directly with your order data, browse history, and customer segments. This lets you send messages that feel personal rather than generic — and that's what drives purchases.
Choosing an Email Marketing Platform for Shopify
The right platform depends on your store's size, budget, and how sophisticated you want your automations to be. Three platforms dominate the Shopify ecosystem:
Klaviyo is the industry standard for growing and established Shopify stores. Its native Shopify integration pulls in real-time order, browse, and cart data, making hyper-targeted automations straightforward. Klaviyo's flows are powerful and its segmentation engine is genuinely best-in-class. The tradeoff: it gets expensive quickly as your list grows, and the free tier is limited to 250 contacts.
Omnisend offers a strong Shopify integration at a lower price point than Klaviyo. It blends email with SMS and push notifications in a single workflow, which is useful if you want a multi-channel approach without managing separate tools. Omnisend's automation builder is more approachable for beginners than Klaviyo's.
Mailchimp is the name most people recognize, and it works with Shopify — but it's worth noting that the native integration has historically been less seamless than Klaviyo or Omnisend. Mailchimp is better suited to content businesses and smaller stores. If you're early-stage and budget-constrained, the free plan gives you room to learn.

Key Features to Look For
Not all email platforms are built the same. When evaluating options for your Shopify store, prioritize these capabilities:
Shopify-Native Integration
The platform should connect directly to Shopify — not through a third-party Zapier connection. Native integration means:
- Real-time sync of customer and order data
- Ability to trigger flows based on Shopify events (purchase, cart abandonment, product views)
- Revenue attribution tied to individual emails
Behavioral Triggers
The most effective emails aren't scheduled campaigns — they're triggered by what a customer actually does. Look for:
- Abandoned cart flows
- Browse abandonment (triggered when someone views a product but doesn't add to cart)
- Post-purchase sequences
- Win-back flows for lapsed customers
Segmentation Engine
Your ability to target the right people with the right message depends on segmentation. A good platform lets you build segments based on:
- Purchase history (what they bought, when, how much they spent)
- Email engagement (opens, clicks)
- On-site behavior
- Predictive data (predicted lifetime value, churn risk)
A/B Testing
Before scaling any campaign, you need to know what works. Look for platforms that support testing subject lines, send times, and email content.
Setting Up Your First Automations
If you do nothing else after connecting an email platform to your Shopify store, set up these three automations. They'll run in the background and generate revenue without ongoing effort.
1. Welcome Series (3–5 emails)
When someone subscribes to your list for the first time, you have their full attention. A welcome series is your chance to make a strong first impression and drive an early purchase.
A simple structure:
- Email 1 (immediately): Welcome + your brand story + soft offer
- Email 2 (Day 2): Best-sellers or most popular products
- Email 3 (Day 4): Social proof — reviews, press mentions, customer photos
- Email 4 (Day 7): Stronger offer or urgency if they haven't purchased
2. Abandoned Cart Recovery
Cart abandonment rates hover around 70% for most Shopify stores. An abandoned cart flow recovers a meaningful chunk of that revenue.
Start with a 3-email sequence:
- Email 1 (1 hour after abandonment): Gentle reminder, no discount
- Email 2 (24 hours): Highlight reviews or address common objections
- Email 3 (48–72 hours): Optional offer — but only if your margins support it
3. Post-Purchase Sequence
Most stores focus entirely on acquisition and forget about the customer once they've bought. Your post-purchase sequence changes that.
A basic 4-email sequence:
- Email 1: Order confirmation + what to expect
- Email 2 (Day 7): Check-in, care instructions if relevant, ask for a review
- Email 3 (Day 14–21): Cross-sell related products
- Email 4 (Day 30–45): Replenishment reminder if the product runs out
Segmentation Strategies That Drive Revenue
Batch-and-blast emails — sending the same message to your entire list — consistently underperform targeted campaigns. Once you've built a list of a few hundred subscribers, start segmenting.
By purchase history: Customers who've bought twice are your best candidates for a loyalty offer. First-time buyers need a different message than VIPs who've spent $500+.
By engagement: Separate your engaged subscribers (opened in last 90 days) from unengaged ones. Suppress the unengaged from your main campaigns — it keeps your deliverability healthy and lets you run a specific re-engagement flow for lapsed contacts.
By product interest: If someone bought running shoes, they're probably not interested in your dress shoe collection. Segment by product category and personalize accordingly.
By acquisition source: Subscribers from a pop-up discount offer behave differently than those who signed up after a purchase. Tailor the messaging.
Measuring ROI
Email marketing generates revenue, but you need to track it properly to know what's actually working.
Revenue per email sent (RPE): Total revenue from an email divided by the number of emails delivered. This normalizes for list size and lets you compare campaign performance over time.
Click-to-purchase rate: Of everyone who clicked, what percentage bought? This tells you whether your landing pages and offers are converting.
Flow revenue: For automations, track cumulative revenue and attributed revenue per recipient. Your abandoned cart flow should be generating meaningful revenue on its own.
List growth rate: A shrinking list is a warning sign. Track your net subscriber growth monthly.
One caveat on attribution: email platforms tend to over-attribute revenue using last-click models. Klaviyo's default attribution window is fairly generous. Treat email revenue numbers as directional, not exact.
Getting Started
The best time to connect an email platform to your Shopify store was before you launched. The second-best time is now.
For stores under 500 subscribers: Start with a free plan (MailerLite, Mailchimp, or Omnisend's free tier) and focus on the welcome series and abandoned cart flow. Don't overthink it.
For stores with 500–5,000 subscribers: This is where Klaviyo or Omnisend start paying for themselves. The advanced segmentation and flow triggers will generate measurable revenue lift.
For stores above 5,000 subscribers: Klaviyo is the clear choice at this stage. The investment in more sophisticated segmentation and predictive analytics pays off at scale.
