In context
Abandonment is not a single failure mode - it's many. Price shock at checkout (shipping, tax) is a common cause. So do account-creation friction, payment-method gaps, trust concerns on first-time visitors, and simple distraction on mobile.
The industry has invented many names for adjacent moments - browse abandonment (no cart at all), checkout abandonment (started checkout, did not complete it), and post-purchase returns or regret. There is no universal 24-hour definition of post-purchase regret. Each requires a different intervention. Generic "you left items in your cart" emails are only a fraction of the actual playbook. For a stated observation window, cart abandonment rate is carts without a completed purchase divided by eligible carts created, multiplied by 100. Define cart deduplication and late-purchase handling before comparing rates.
How Zubby uses this
Zubby watches for abandonment signals in the session, such as exit intent and an idle cart, and the agent can step in with a clarifying question or an offer you have approved. If the shopper still leaves, Zubby sends a recovery email written from the cart contents - from your own connected mailbox (Microsoft 365, Google Workspace, or SMTP) when configured, or an available platform fallback sender. A fallback depends on operator configuration and does not guarantee delivery. Consent, unsubscribe and purchase suppression still apply. Klaviyo and Mailchimp connections sync shopper data for your own flows; they are not used to send Zubby's recovery emails.
Recovered carts are reported per store in the dashboard, so you can judge the result on your own numbers rather than an industry average.
