Email Marketing for Shopify — From Setup to Automation

Email marketing has the highest ROI of any digital channel — roughly $36 for every $1 spent. With Shopify, you already have a list of real customers ready to engage. The problem is most merchants do almost nothing with it beyond the automatic order confirmation email.

Shopify Email vs Klaviyo — when to use which

Shopify Email is the right starting point. It lives inside Admin — no extra integration needed, drag-and-drop templates are easy to use, and emails are sent from your store's own domain. The first 10,000 emails per month are free, then $1 per additional 1,000 — very cheap compared to Klaviyo at equivalent list sizes.

When to switch to Klaviyo? When your list exceeds 500–1,000 subscribers and you want more sophisticated segmentation — like sending different emails to first-time buyers, second-time buyers, and fifth-time buyers; or predictive analysis of "is this customer likely to buy again within 30 days?" Klaviyo is also stronger for A/B testing individual email elements — essential when you're optimizing at scale.

Building your email list — don't just wait for purchases

Customers who place orders are automatically subscribed if they check the "Subscribe" box at checkout. But that checkbox opt-in rate is typically only 30–50%, meaning more than half your paying customers aren't being nurtured further. You need active collection points:

• Popup with a real offer — "10% off your first order" massively outperforms "Subscribe to our newsletter" alone. Add light urgency: "Valid today only" — but only if it's actually true, not perpetually recycled
• Footer form — Always present, for people who actively want to follow along. Simple: email input + button
• Checkout opt-in — Enable in Settings → Checkout → "Email marketing." Best practice: pre-checked for returning customers, unchecked for new (for deliverability)
• Content / free resource — Offer a guide or checklist in exchange for an email. Subscribers who sign up for content have higher quality intent than discount-hunters

⚠️ Never buy email lists or import emails without clear opt-in. Beyond the legal issues (GDPR, CAN-SPAM), sending to non-subscribers generates spam reports — and after a few reports, your domain enters blacklists, meaning even legitimate customer emails stop reaching inboxes. This takes months to recover from.

The 5 essential email automations

1. Welcome email series

The first email after signup — sent within 5 minutes. Welcome emails have the highest open rates of any type: 50–70%. This isn't the time to push a sale — introduce your brand story, why you do what you do, and your bestselling products. Email 2 (2–3 days later): a specific offer or strong social proof (reviews, customer case studies). Email 3 (5–7 days): if no purchase yet, revisit the offer with slightly more urgency.

2. Abandoned cart (1hr and 24hr)

First email (after 1hr): keep it simple — "Did you forget something?" + product image + link back to cart. No discount needed. This email works through pure reminder, not incentive. Second email (24hr): add social proof — "238 people bought this product this week" — or a small offer if you want. Average abandoned cart open rate: 40–45%; recovery rate: 5–15% depending on category.

3. Post-purchase series

Email 1 (immediately): confirmation + tracking. Email 2 (3–5 days after delivery): "Got your order? How's it going?" + link to leave a review. Review request emails sent at the right time (when the customer is using the product for the first time) get 3x higher response rates than emails sent too late. Email 3 (2 weeks later): suggest related products based on what they bought.

4. Basic segmentation

Three most important segments to start with: (1) Subscribers who haven't bought — they need trust-building and social proof, (2) One-time buyers — need nurturing to become repeat customers, use the post-purchase series, (3) VIP / high-spend customers — give them exclusive early access and offers, don't lead with discounts since they're already loyal. Each group needs different content — a mass blast to everyone is the fastest way to spike unsubscribe rates.

5. Win-back campaign

Customer hasn't opened emails in 60 days or hasn't purchased in 90 days — send a "We miss you" email with a special offer and warm tone. If no response in 2 weeks, send a "sunset" email: "We'll stop emailing you — click here if you'd like to stay subscribed" — those who don't click get unsubscribed. A clean list beats a large list because deliverability stays strong.

Metrics to track weekly

Low open rate: problem is the subject line or sender name. Low click rate: problem is the content or CTA placement. High unsubscribes: you're sending too frequently or the content isn't relevant. Prioritize fixing unsubscribe and spam rates first — they affect the deliverability of your entire list, not just individual campaigns.
