Email marketing automation

Email Marketing Automation#

Overview#

Triggered email flows automatically send personalized messages based on customer behavior and lifecycle stage, achieving 3–5x higher open rates than broadcast campaigns. Klaviyo (for Shopify/BigCommerce) and AutomateWoo or Klaviyo plugin (for WooCommerce) provide pre-built flow templates for the four critical flows: welcome series, post-purchase nurture, win-back campaigns, and browse abandonment. Most merchants can set these up without writing any code.

When to Use This Skill#

• When setting up a new store and needing baseline lifecycle email coverage
• When replacing manual one-off campaigns with behavior-triggered sequences
• When recovering revenue from customers who browsed but did not purchase
• When re-engaging lapsed customers who have not ordered in 60–180 days
• When personalizing post-purchase communication to reduce returns and increase LTV

Core Instructions#

Step 1: Choose the right tool#

Step 2: Set up the four core flows#

Shopify with Klaviyo#

Install Klaviyo from the Shopify App Store. Klaviyo automatically tracks Shopify events — no additional setup required for event capture.

Flow 1: Welcome Series

1. Go to Klaviyo → Flows → Create Flow → Welcome Series (use the pre-built template)
2. The default template sends 3 emails:
   • Email 1 (immediate): Welcome + brand story + 10% discount for first purchase
   • Email 2 (day 2): Bestsellers or curated collection
   • Email 3 (day 7): Brand mission / social proof
3. Customize the email copy and design using Klaviyo's drag-and-drop editor
4. The flow triggers automatically when someone subscribes via your Shopify popups, checkout opt-in, or newsletter form
5. Add a conditional split on "Has placed an order" to skip the discount email for customers who already purchased after subscribing

Flow 2: Post-Purchase Series

1. Go to Klaviyo → Flows → Create Flow → Post-Purchase (use template)
2. Default 4-step structure:
   • Email 1 (immediate): Order confirmation + product care tips
   • Email 2 (day 2): Shipping notification (Klaviyo connects to Shopify's fulfillment events)
   • Email 3 (day 7): Delivery check-in + cross-sell recommendations
   • Email 4 (day 21): Review request (connects to Klaviyo's review integration or Judge.me)
3. Add a filter: "Has NOT placed order since starting this flow" → skip the review request if they ordered again (they are already happy)

Flow 3: Browse Abandonment

1. Go to Klaviyo → Flows → Create Flow → Browse Abandonment (use template)
2. Trigger: Viewed Product metric
3. Wait 30 minutes → Check: "Has NOT started checkout since flow start" → send email
4. Email content: Use Klaviyo's Dynamic Product Block — it automatically shows the exact product the customer was viewing with live price and image
5. Wait 24 hours → Send follow-up with "Others also liked" product recommendations

Flow 4: Win-Back / At-Risk

1. Go to Klaviyo → Flows → Create Flow → Win Back (use template)
2. Trigger: Segment membership → "Predicted Churn Risk: High" (Klaviyo calculates this automatically)
3. Default 3-step structure:
   • Email 1 (day 0): "We miss you" + personalized product recommendations based on past purchases
   • Email 2 (day 7): Social proof + new arrivals
   • Email 3 (day 14): Final offer with 10–15% discount + expiry date
4. Add a flow filter: "Has not placed an order" — this ensures the flow stops immediately when the customer converts

WooCommerce with AutomateWoo#

1. Go to AutomateWoo → Workflows → Add Workflow

Welcome Series:

• Trigger: Customer → Created (new customer account) or Subscribe → Newsletter (with your email plugin)
• Add 3 email actions with timing delays: immediate, +2 days, +7 days
• Use AutomateWoo's variable system to insert first name, recommended products, etc.

Post-Purchase Series:

• Trigger: Order → Status Changed to Completed
• Action 1 (immediate): Send order confirmation email
• Action 2 (+7 days): Send review request (AutomateWoo integrates with YITH Reviews and WooCommerce Reviews Pro)
• Add Rule: "Order was placed by this customer" and "Customer has not created a review for this order"

Browse Abandonment:

• Requires: AutomateWoo Pro + the Browse Abandonment add-on
• Trigger: Browse Abandonment → Wait 30 minutes → Send email with viewed product

Win-Back:

• Trigger: Customer → Win Back (built-in AutomateWoo trigger)
• Set "No order in the last" to 60 days
• Create 3 workflows for escalating interventions at 60, 90, and 120 days

BigCommerce#

1. Install Klaviyo from the BigCommerce App Marketplace
2. Klaviyo syncs all BigCommerce order and browse events automatically
3. Follow the same Klaviyo flow setup as the Shopify instructions above
4. BigCommerce does not have an equivalent to Shopify's native abandoned checkout emails — Klaviyo handles this entirely

Custom / Headless#

Send behavioral events to Klaviyo's API, then build flows in Klaviyo's visual editor:

// Track key events via Klaviyo's Events API
async function trackKlaviyoEvent(email: string, eventName: string, properties: object) {
  await fetch('https://a.klaviyo.com/api/events/', {
    method: 'POST',
    headers: {
      'Authorization': `Klaviyo-API-Key ${process.env.KLAVIYO_PRIVATE_KEY}`,
      'Content-Type': 'application/json',
      'revision': '2024-10-15',
    },
    body: JSON.stringify({
      data: {
        type: 'event',
        attributes: {
          metric: { data: { type: 'metric', attributes: { name: eventName } } },
          profile: { data: { type: 'profile', attributes: { email } } },
          properties,
          time: new Date().toISOString(),
        },
      },
    }),
  });
}

// Usage:
await trackKlaviyoEvent(customer.email, 'Viewed Product', {
  ProductName: product.name, ProductID: product.id,
  ImageURL: product.imageUrl, URL: product.url, Price: product.price,
});

await trackKlaviyoEvent(customer.email, 'Placed Order', {
  $value: order.subtotal, OrderId: order.id,
  Items: order.lineItems.map(i => ({ ProductName: i.name, ItemPrice: i.price })),
});

Once events are flowing into Klaviyo, build the flows in Klaviyo's visual editor using the same instructions as the Shopify section.

Step 3: Configure suppression and frequency rules#

In Klaviyo:

• Enable Smart Sending on all flows: go to each flow, click the email step, and toggle "Smart Sending" on — this prevents sending more than 1 email per 16-hour window to any contact
• Set a daily message limit under Account Settings → Email Sending Limits
• Add "Unsubscribed from email" as a Flow Filter on every flow — contacts unsubscribed from Klaviyo will not receive flow emails regardless, but this makes the logic explicit

In AutomateWoo:

• Go to AutomateWoo → Settings → Email and configure sending limits
• Add "Customer has unsubscribed" as a Rule on every workflow

Step 4: Measure flow performance#

In Klaviyo: go to Flows → [Flow name] → Analytics to see revenue, open rate, and click rate per email step.

Best Practices#

• Use Klaviyo's pre-built flow templates — they incorporate years of industry learning; customize the copy and design, not the flow structure
• Cancel competing flows — in Klaviyo, use flow filters: "Has placed an order since starting flow → exit flow"; this prevents win-back emails reaching customers who just bought
• Personalize with dynamic product blocks — Klaviyo's product recommendation blocks automatically show the right products based on browsing and purchase history
• Respect quiet hours — Klaviyo's Smart Sending respects timezone-based sending windows; enable it on all flows
• A/B test subject lines — Klaviyo's built-in A/B test sends to 20% of recipients and picks the winner automatically; use it on every flow's first email
