Cart Abandonment Flows That Recover 15–25% of Lost Revenue

Nearly 70% of online shopping carts are abandoned. For a store doing $50K per month, that means roughly $115K in potential revenue was left behind. You won’t recover all of it, but a well-built abandoned cart flow in Klaviyo can realistically recover 5–15% of those abandoned checkouts.

Here’s how to set it up properly with exact Klaviyo settings, proven subject lines, and the email structure that gets results.

Klaviyo Flow Settings

• Trigger: Metric — Checkout Started
• Flow Filter: Has not Placed Order since starting this flow
• Profile Filter: Has been in this flow zero times in the last 7 days (prevents repeat sending)
• First email delay: 1 hour after trigger
• Smart Sending: ON

The 3-Email Cart Recovery Sequence

Email 1 — The Simple Reminder (1 Hour)

Don’t overthink this one. Show the product image with dynamic cart contents (Klaviyo pulls this automatically), a clear headline like “You left something behind,” and one big CTA button back to checkout. No discount in this email — many people just got distracted and will complete the purchase with a simple reminder.

Email 2 — Address Objections (24 Hours)

If they didn’t buy after Email 1, something is holding them back. This email should address the most common objections for your store. Include your shipping policy, return/exchange guarantee, sizing guide if applicable, and 1–2 customer reviews for the specific products in their cart. Build confidence.

Email 3 — Final Nudge with Incentive (48 Hours)

This is your last attempt. If your margins allow, offer a small incentive — 5–10% off or free shipping. Create urgency by giving the offer a 24-hour deadline. Use a subject line that signals this is the final reminder.

10 Subject Lines That Recover Carts

1. You left something behind
2. Still thinking it over?
3. Your cart is waiting — complete your order
4. Did something go wrong? Your items are saved
5. [First Name], your cart expires soon
6. Don’t miss out — these sell fast
7. Complete your order and get free shipping
8. Your [Product Name] is almost gone
9. We saved your cart (but not for long)
10. Last chance: [X]% off your cart — today only

Preheader Examples

• Your items are still in your cart — complete your order before they’re gone
• We saved your cart. Come back and finish what you started
• This is your last reminder — your cart expires tonight

A/B Testing Ideas

• Timing: Test 1-hour vs 4-hour delay for Email 1. Some audiences respond better to a longer gap.
• Discount vs no discount: Test Email 3 with a 10% off code vs no discount. You may find the reminder alone is enough.
• Subject line style: Test question-based (“Still thinking?”) vs urgency-based (“Your cart expires soon”) subject lines.
• Social proof placement: Test adding customer reviews to Email 1 vs keeping it minimal.

Performance Benchmarks

If your recovery rate is below 5%, the most common issues are: sending the first email too late (should be 1 hour, not 24 hours), weak CTAs that don’t link directly back to the checkout, or missing product images in the email.
