Most abandoned cart flows have one problem: they exist, so everyone assumes they work. The trigger fires, an email goes out, and nobody looks at it again for two years.
This is the three-email abandoned cart email sequence we build in Klaviyo, the timing behind it, and the setup checks that matter more than the copy.
Looking for the copy and examples? Our abandoned cart email sequence guide covers that. This post is about the Klaviyo setup behind it.
Start with the trigger, not the subject line
Before you write a word, confirm three things in the flow settings.
- The trigger is Checkout Started, not Added to Cart. Added to Cart catches browsers. Checkout Started catches people who gave you an email address and a shipping intent.
- The flow filter excludes anyone who has placed an order since starting the flow. Without it, someone who bought after email one still gets email two.
- Smart sending and profile filters are set on purpose. If smart sending is on, a customer who got a campaign an hour ago may skip your cart email entirely.
Fix these first. A great email sent to the wrong person, or not sent at all, recovers nothing.
The three emails
Email 1: about one hour after checkout starts. The reminder. No discount. Show the cart contents with images, the price, and one clear button back to checkout. The goal is to remove friction, not to persuade. Most people who abandon were interrupted, not undecided.
Email 2: about 24 hours later. The objection handler. This is where you answer the questions that stop people at checkout: shipping time, return policy, what it feels like to use the product, a short review or two. Pick the two objections your customers raise most often and answer them directly.
Email 3: 48 to 72 hours after the start. The last nudge. Create honest urgency if you have it, such as limited stock or a shipping cutoff. If you offer an incentive anywhere in this sequence, this is the place, and only for customers who have not bought from you before. Giving a code in email one trains your customers to abandon on purpose. We cover that pattern in why welcome flow discounts teach customers to wait.
What to add after the basics work
- A split on cart value. A $30 cart and a $300 cart should not get the same sequence. Higher carts can justify a fourth email or a plain-text note from a real person.
- A split on new versus returning customers. Returning customers rarely need an incentive. New customers might.
- Product-specific content. If a product has a common question, pull it into the email dynamically for carts that include it.
- SMS as a second channel, but only for people who gave SMS consent, and only for the first or last touch.
How to tell if it is working
Open the flow analytics in Klaviyo and look at three numbers per email: placed order rate, revenue per recipient, and unsubscribe rate. Open rate alone tells you very little. If email 1 has a healthy open rate and a low placed order rate, the email is being read but the checkout is the problem. If opens are low across the whole flow, look at deliverability before you rewrite anything. Our guide to reading your flow numbers walks through that order of diagnosis.
The mistakes we see most often
- Only one email in the flow
- A discount in the first email
- No flow filter, so buyers keep getting cart reminders
- Cart emails going to spam because the sending domain was never authenticated
- Dynamic cart blocks that break on mobile and show an empty box
If your abandoned cart revenue has dropped and you are not sure why, start with the sending domain. A broken flow and a blocked flow look identical in a dashboard. Run the free scan and we will check the three settings inboxes look at first, SPF, DKIM and DMARC, in about ten seconds.
