Klaviyo Abandoned Cart Flow Not Sending? How to Fix It

An abandoned cart flow is usually the single most profitable automation a store has. When it stops sending, you do not get an error. You just stop recovering orders, and nobody notices for weeks. If yours is not sending, work through this list in order.

1. Is the flow actually live?

Open the flow and check its status. Draft, manual and paused flows send nothing. Also check each email inside the flow. An individual email set to draft or manual will block everything after it. This is the most common cause and takes thirty seconds to rule out.

2. Is the store integration sending the event?

The flow is triggered by a Started Checkout event from your store. In Klaviyo, open Analytics, then Metrics, and look at Started Checkout over the last few days. If the count is zero or has dropped sharply, the integration has a problem: a disconnected app, an expired connection or a checkout change. Reconnect the integration and place a test checkout.

3. Did the trigger or filters change?

Read the trigger and the flow filters. A filter such as "has not placed an order" is normal, but stacked filters, an old list requirement or a rule that excludes anyone without a particular property can quietly remove most of the audience. Compare how many people entered the flow this month with last month.

4. Is the person even eligible to receive email?

Klaviyo only emails people who have given consent and are not suppressed. If your checkout does not collect email consent clearly, many abandoners will never be emailed. Check how your checkout and signup forms handle consent, and look at the suppression list for unexpected growth.

5. Check smart sending and timing

Smart sending skips a message to anyone who recently received an email from you. If you send frequent campaigns, a large share of cart abandoners may be skipped. Review the setting on each email and decide whether the abandoned cart emails should override it. Also look at the delays: a wait that is too long means people come back and buy before the email arrives.

6. Look at the exit conditions

People should leave the flow the moment they buy. If the flow is configured to filter out anyone who recently placed an order, check that the filter looks at the right metric. A mistake here can remove nearly everyone.

7. Rule out deliverability

If emails are marked as sent but revenue is near zero, they may be landing in spam. Authentication gaps in SPF, DKIM or DMARC and a damaged sender reputation are common causes, and they hit every flow at once. Read why Klaviyo emails go to spam and see how the deliverability fix works. For the full process, use the Klaviyo flow performance audit.

Want a second pair of eyes?

If you have been through the list and the flow still is not performing, I can look at it. The Flow Bundle covers the audit, the deliverability fix and four core flows, including abandoned cart, for $2,500 one time. Compare the options on the pricing page.
