On the stores I manage, cart abandonment recovery alone accounts for 8 to 15% of total revenue. It's by far the best return-on-investment feature in all of e-commerce: it costs a few dozen euros a month in tooling and generates thousands of euros in sales that would otherwise be lost for good. Yet most stores I audit at the start of an engagement have either no sequence at all, or a sloppy single-email version. Here's the full sequence, tested and refined across more than 50 PrestaShop, Shopify, and WooCommerce stores.
Why customers abandon their cart
Before building the sequence, you need to understand the causes. Studies converge on the same patterns: shipping costs discovered too late (48% of cases), a forced account creation step (24%), a checkout process that's too long or confusing (18%), lack of trust in payment security (17%), and simple distraction or price comparison on another site (a large share of the remainder). Some of this is fixed upstream — showing shipping costs on the product page, offering guest checkout — but a meaningful share will always remain, and that's exactly where a recovery sequence comes in.
Email 1 — Sent at T+1 hour
Subject: Forgot something? The tone should feel like a helpful service, never salesy or guilt-tripping. Include a clear photo of the products left in the cart, a button that leads directly back to the filled cart (not the homepage), and nothing else. Crucially, offer no discount at this stage: a customer who was simply interrupted — a phone call, a kid demanding attention — will come back on their own if you make the path easy. On my clients' stores, this single email alone recovers 30 to 40% of the total sales generated by the whole sequence.
Email 2 — Sent at T+24 hours
Subject: Still interested in [product]? At this stage, focus on building trust rather than pushing the product itself: verified customer reviews on the items in question, concrete reassurance (real delivery timelines, a simple return policy, secure payment methods), and possibly a short FAQ addressing common objections (size, compatibility, lead time). Still no discount. This is the email that addresses the psychological friction points identified above.
Email 3 — Sent at T+72 hours
Subject: One last thing… This is where, and only where, the commercial incentive comes in: a 10% discount valid for 48 hours, with a unique, tracked code so you can measure this email's performance precisely. The sense of urgency needs to stay genuine — a real expiry date, not a fake countdown that resets on every visit: customers spot fake urgency very quickly, and it damages brand trust over the long run.
Optional SMS — Sent at Day+5
Reserved for carts above €100, a short SMS with a direct link back to the cart can unlock the undecided shoppers who no longer check their inbox. SMS conversion rates are typically 3 to 5 times higher than email for this type of recovery, provided you don't overdo it — a single SMS, never more, so it doesn't feel intrusive.
Recommended tools by platform
On PrestaShop, native modules are enough for a basic sequence; for finer segmentation, I connect Sendinblue (Brevo) or Mailchimp via API. On Shopify, Klaviyo remains the undisputed industry reference, with ready-made flows and advanced behavioral segmentation. On WooCommerce, MailPoet works well for small stores, while Klaviyo or Brevo take over once order volume grows.
Mistakes that kill your recovery rate
The first, very common mistake is waiting 24 hours before the first email: beyond 2 to 3 hours, purchase intent has already largely faded. The second is opening directly with a discount: it conditions customers to systematically abandon their cart to get a markdown, which erodes your margins over time. The third is forgetting the SMS channel for high-value carts, even though it's often the only channel that still cuts through customer attention today. Finally, a sequence that doesn't segment by cart value or product category loses relevance, and with it, effectiveness.
What to remember
A well-built recovery sequence isn't a marketing gimmick — it's a profitability pillar for any online store. With just three emails and an optional SMS, properly sequenced and without an early discount, recovering 15 to 25% of otherwise fully lost sales is a realistic outcome.
