Complete Klaviyo Guide for Shopify: Setup and Strategy

The Complete Klaviyo Guide for Shopify in 2026

Klaviyo is the most powerful email marketing platform for Shopify. Full stop. At Growth Lab, it's the first tool we install on every eCommerce store we manage. Why? Because a properly configured Klaviyo account can add 15-30% in additional revenue to your store without spending a single extra dollar on advertising.

Here's how to set it up correctly and which flows to implement for maximum results.

Initial Setup: Building the Foundation

Step 1: Connect Klaviyo to Shopify

• In Klaviyo, go to Integrations > Shopify
• Enter your Shopify store URL and authorize the connection
• Klaviyo will automatically sync your products, orders, and customers
• Important: verify these events are properly tracked: Viewed Product, Added to Cart, Started Checkout, Placed Order

Step 2: Configure Your Sending Domain

• Add a dedicated sending subdomain (e.g., send.yourstore.com)
• Configure DNS records (DKIM, SPF) to maximize deliverability
• Don't skip this step: poor DNS setup = your emails land in spam

Step 3: Create Your Collection Forms

• Welcome pop-up: offer 10-15% off in exchange for email. Trigger after 5-10 seconds or at 50% scroll.
• Exit-intent form: capture visitors who are about to leave
• Footer form: always visible for those who prefer to scroll
• Target: a capture rate of 3-5% of your visitors

Step 4: Segment Your Existing List

Import your existing contacts and create these foundational segments:

• Engaged 30 days: opened or clicked an email in the last 30 days
• Engaged 90 days: same, 90 days
• VIP customers: spent more than $X (define your threshold)
• At-risk customers: purchased 60-90 days ago but haven't repurchased
• Never purchased: subscribers who haven't converted

The 6 Essential Flows to Set Up

1. Welcome Series

Trigger: New email list subscription

Recommended structure:

• Email 1 (immediate): Deliver the discount code + brand introduction
• Email 2 (day 2): Your story, your values, why you're different
• Email 3 (day 4): Best sellers and customer testimonials
• Email 4 (day 6): Reminder that the discount code expires soon

Expected revenue: This flow should generate 20-30% of your total email revenue.

2. Abandoned Cart

Trigger: Product added to cart, checkout not completed

Recommended structure:

• Email 1 (1 hour after): "Did you forget something?" + product image
• Email 2 (24 hours): Reminder with social proof (customer reviews)
• Email 3 (48 hours): Last chance + incentive (free shipping or small discount)

Expected revenue: Recovery rate of 5-15% of abandoned carts.

3. Browse Abandonment

Trigger: Product viewed but not added to cart

Recommended structure:

• Email 1 (2-4 hours after): "This caught your eye" + product image
• Email 2 (24 hours): Similar products + bestsellers

Important: Only send this flow to engaged contacts to avoid being flagged as spam.

4. Post-Purchase

Trigger: Order placed

Recommended structure:

• Email 1 (immediate): Confirmation + warm thank you (not just the transactional receipt)
• Email 2 (day 3): Product usage tips
• Email 3 (day 7): Review request
• Email 4 (day 14): Cross-sell complementary products

Goal: Turn a one-time buyer into a repeat customer.

5. Win-Back

Trigger: Customer hasn't purchased in 60-90 days

Recommended structure:

• Email 1: "It's been a while! Here's what's new"
• Email 2 (7 days later): Exclusive offer to come back
• Email 3 (14 days later): Final attempt with a more aggressive offer

Expected revenue: Reactivation rate of 3-8% of dormant customers.

6. Sunset (Disengagement)

Trigger: Contact hasn't opened an email in 120-180 days

Recommended structure:

• Email 1: "Do you still want to hear from us?"
• Email 2 (7 days): Last chance before removal

Goal: Clean your list to maintain strong deliverability. Remove those who don't respond.

Advanced Strategies to Maximize Revenue

Behavioural Segmentation

Don't treat all customers the same:

• New customer: focus on education and trust
• Repeat customer: focus on loyalty and what's new
• VIP customer: exclusive access, early releases, special treatment
• At-risk customer: personalized win-back offers

Systematic A/B Testing

Continuously test:

• Subject lines: try emoji vs. no emoji, questions vs. statements, short vs. long
• Send times: our data shows optimal times vary by segment
• Content: one image vs. many, long copy vs. short, with CTA vs. without

SMS as a Complement

Klaviyo also supports SMS. Use it for:

• Abandoned cart reminders (recovery rate 2-3x higher than email)
• Product launches
• Flash sales
• Caution: don't overdo it. 2-4 SMS per month maximum.

Metrics to Monitor

• Open rate: aim for 40%+ on flows, 25%+ on campaigns
• Click rate: aim for 3-5% on flows
• Revenue per recipient: the most important metric
• Unsubscribe rate: keep it under 0.3% per send
• Email attribution: aim for 25-35% of total revenue coming from email
