Key takeaways
- Most abandoned baskets reflect distraction, doubt or friction, not rejection, so emails should remind and reassure.
- Cart reminders are likely to be direct marketing in the UK, so build consent or the soft opt-in into checkout.
- Use two or three emails with distinct jobs, and hold discounts back rather than leading with them.
- Measure incremental sales with a holdout group instead of trusting platform-reported recovered revenue.
Abandoned cart emails are automated messages sent to shoppers who added products to their basket or started checkout but did not complete the purchase. A good sequence usually has two or three emails over a few days, reminds people what they left, removes the doubt that stopped them, and makes it effortless to return to a saved basket. Done well, it is one of the most directly profitable automations an online shop can run.
This guide covers how to set one up properly: the data you need, the legal position in the UK, timing, content, discounts and how to tell whether your emails are actually recovering sales.
Why shoppers abandon carts in the first place
Before writing a single email, it helps to understand that most abandonment is not a rejection of your product. People leave baskets for ordinary reasons:
- They were browsing or comparing. The basket doubled as a wish list while they checked other shops.
- Unexpected costs. Delivery charges or taxes appeared late in checkout.
- Delivery or returns uncertainty. They could not see when the item would arrive or how easy it would be to send back.
- Checkout friction. A forced account creation, a long form or a missing payment option.
- Distraction. A phone call, a meeting, a child, a train stop.
- Doubt about the product. Sizing, compatibility or quality questions that the product page did not answer.
Some of these are best fixed on the website rather than in email. If the same objection keeps appearing, such as surprise delivery costs, solving it at source will lift your conversion rate for every visitor, including the many you have no email address for. Our guide on what a good conversion rate looks like is a useful companion here.
How cart, checkout and browse abandonment differ
These terms are often used interchangeably, but they describe different moments and need slightly different emails.
| Type | Trigger | What you know | Typical tone |
|---|---|---|---|
| Browse abandonment | A known subscriber viewed products but added nothing | Interest in a product or category | Light, helpful, suggestion-led |
| Cart abandonment | A known contact added items to the basket and left | Specific products and quantities | Reminder with product details |
| Checkout abandonment | Someone entered their email at checkout but did not pay | Products, often delivery details, strong intent | Direct, reassuring, easy return to checkout |
The key constraint is that you can only email people you can identify. That means logged-in customers, existing subscribers recognised by your email platform’s tracking, or shoppers who typed their email into the checkout before leaving. This is why many shops ask for the email address as the first checkout field.
PECR, consent and the UK rules
An email reminding someone about products they left behind, especially one that encourages them to complete the purchase, is likely to count as direct marketing under the Privacy and Electronic Communications Regulations (PECR). That means you need a lawful basis to send it.
You have two routes open to you:
- Consent. The shopper has opted in to marketing email, for example through an unticked box at checkout or an earlier newsletter sign-up.
- The soft opt-in. You collected their email during the negotiation of a sale of your products, you are marketing your own similar products, and you gave them a clear chance to opt out at the point of collection and in every message. A checkout where the shopper has entered their email address and you have shown a clear opt-out at that point may fit this, but it needs to be designed with that in mind.
For most shops, that means adding a clear notice and opt-out option at the email field in checkout, recording it, and honouring opt-outs in your automation. UK GDPR also applies to the personal data you process, so your privacy notice should explain that you may send reminders. Because guidance is updated from time to time, check the ICO’s current position when you configure your checkout, and take advice if you are unsure.
Every abandoned cart email should also include a working unsubscribe link and identify your business clearly.
What you need before you build the flow
Most ecommerce email platforms and shop systems support abandoned cart flows, and Shopify includes a basic abandoned checkout email out of the box. For anything more sophisticated, check these foundations first:
- Store integration. Your email platform must receive cart and checkout events, including product names, images, prices and a link that restores the basket.
- Identity capture. Email collected early in checkout, plus tracking that recognises subscribers when they click through from your emails.
- Exit conditions. The flow must stop the moment someone purchases, so nobody gets a reminder for an order they have already placed.
- Frequency limits. Rules that prevent a shopper who abandons several times in a week from receiving a pile of near-identical emails.
- Authenticated sending. SPF, DKIM and DMARC set up on your sending domain so the emails reach the inbox.
If your shop runs on Shopify and the data is not flowing cleanly, our Shopify development team can sort out the integration so your automations have accurate information to work with.
How to structure an abandoned cart sequence
There is no single correct timing, and the right rhythm depends on your products and buying cycle. A low-cost impulse purchase suits a quicker sequence; a sofa or a piece of specialist equipment justifies a longer, more informative one. As a sensible starting point to test against, many shops use something like this:
- Email 1, roughly one to a few hours after abandonment: a simple reminder. Show the products, the price and a prominent button back to the saved basket. No discount.
- Email 2, around the next day: address the likely objection. Delivery times, returns policy, sizing help, warranty, customer reviews or a way to ask a question.
- Email 3, a couple of days later: a final nudge. Mention limited stock only if it is true, or, if your margins and strategy allow, a modest incentive.
Test the timing rather than copying it. The first email in particular should not arrive so quickly that it feels like surveillance, or so late that the shopper has bought elsewhere.
Splitting by basket value or customer type
Once the basic flow is working, consider branching it:
- High-value baskets might receive a more personal message, an offer of help from a real person, or financing information if you offer it.
- First-time shoppers often need more reassurance about who you are, while returning customers mainly need the reminder.
- Specific categories can get tailored content, such as a size guide for clothing or a compatibility checker for parts.
Good email segmentation keeps these branches manageable instead of turning your automation into a maze.
Writing abandoned cart emails that work
Subject lines
Be clear rather than clever. The reader should know at a glance what the email is about. Subject lines that name the product or just say the basket is saved tend to be more useful than vague teasers. Avoid fake urgency and anything that feels like a telling-off.
The body
Every email should include:
- The product image, name, variant (size, colour) and price, pulled dynamically from the basket.
- A single, prominent button that restores the basket exactly as it was.
- Reassurance relevant to the stage: delivery, returns, secure payment, warranty cover.
- A way to get help, such as replying to the email or using live chat.
- Your business name, address details as required, and a visible unsubscribe link.
Keep the design light. Abandoned cart emails are transactional in feel, even though they are legally marketing, so a short, clear message usually works better than a busy newsletter-style layout.
Tone
Write as a helpful shop assistant, not a debt collector. “You left something behind” works because it is neutral. Avoid guilt, pressure and phrases suggesting you have been watching closely. If you sell considered purchases, invite questions rather than pushing for an immediate decision.
An illustration: a small homeware shop
To make this concrete, imagine a hypothetical independent homeware shop selling lamps, cushions and ceramics. A shopper adds a table lamp and two cushions to the basket, enters their email at checkout, then closes the tab when the delivery date appears.
The first email, sent a few hours later, shows the three items with photos and prices, and a “return to your basket” button. The second, the following day, leads with delivery: the dispatch days, the courier used, how to choose a delivery slot and the returns window, plus a line explaining that each lamp is checked before it is packed. The third, two days later, does not offer money off. Instead it mentions the matching bulbs that come with the lamp and invites the shopper to reply with any questions about sizing or colour.
Nothing in that sequence is pushy. Each email answers a question the shopper probably had when they closed the tab, and the same approach works for shoes, supplements or spare parts.
Should you offer a discount?
Discounts can recover sales, but they carry real costs. If every abandoned basket triggers a code, shoppers learn to abandon on purpose and wait for it. You also give away margin on orders that would have completed anyway.
Some practical guidelines:
- Do not lead with a discount. Keep the first email to a reminder and the second to reassurance.
- Limit incentives to specific cases, such as first-time customers, higher-value baskets or products with healthy margins.
- Consider non-price incentives, such as free delivery, a free sample, extended returns or a gift with purchase.
- Use unique, expiring codes so they cannot be shared on voucher sites.
- Measure the effect by comparing a group that receives the incentive with one that does not.
Fix the checkout as well as the follow-up
An abandoned cart sequence is a safety net. It is not a substitute for a good checkout. Review your own buying journey on a phone and look for these common issues:
| Checkout issue | Fix to consider |
|---|---|
| Delivery costs shown late | Show delivery options and costs on product and basket pages |
| Forced account creation | Offer guest checkout, with an optional account after purchase |
| Long or confusing forms | Remove unnecessary fields; use address lookup and autofill |
| Limited payment options | Add the wallets and methods your customers expect |
| Slow pages | Optimise images, scripts and apps that slow down basket and checkout |
| Unclear returns policy | Summarise it near the add-to-basket button and in checkout |
Speed matters here too. A sluggish checkout loses impatient buyers before you ever get the chance to email them. If your Core Web Vitals are poor, fix them alongside your email work.
Measuring what the flow really earns
Email platforms often report “recovered revenue” generously, crediting any purchase made within a set window after an email was opened or clicked. Some of those shoppers would have come back anyway. To understand the true value:
- Check your attribution window. Know how your platform decides that a sale came from an email, and prefer click-based attribution over opens, which are inflated by privacy features such as Apple Mail Privacy Protection.
- Run a holdout test. Randomly exclude a small portion of abandoners from the flow for a few weeks and compare their purchase rate with those who received the emails. The difference is the incremental effect.
- Track each email separately. If the third email rarely adds anything, shorten the flow; if it does most of the work, examine why the first two are not.
- Watch unsubscribes and complaints. A flow that recovers sales but drives up spam reports is damaging your wider email programme.
- Look at margin as well as revenue. Deduct the cost of discounts to see what the flow actually earns.

A quick setup checklist
- Email captured as the first checkout step, with a clear marketing notice and opt-out.
- Store connected to your email platform, sending cart and checkout events with product data.
- Restore-basket links tested on mobile and desktop.
- Exit condition on purchase and limits on repeat triggers.
- Two or three emails with distinct jobs: remind, reassure, final nudge.
- Discount rules agreed and unique codes set up, if used.
- Holdout group configured to measure incremental sales.
- Unsubscribe link, business details and authenticated sending domain in place.
Where to start with your own flow
Start with the plumbing: check that cart events reach your email platform, that the restore link works on a phone and that purchases end the flow. Once that is sound, write the first two emails, leave discounts out, and set up a holdout group from day one so you know what the sequence adds.
We build and audit these flows as part of our marketing automation service, and our ecommerce growth work looks at the rest of the journey, from first visit through to the second and third order.

How many abandoned cart emails should I send?
Two or three emails is a sensible starting point for most shops. The first reminds the shopper what they left, the second addresses common objections such as delivery or returns, and the third gives a final nudge. More than that risks irritating people and increasing unsubscribes. Test the number and timing against your own buying cycle.
When should the first abandoned cart email be sent?
Many shops send the first reminder within a few hours of abandonment, while the purchase is still on the shopper’s mind. Sending too quickly can feel intrusive, and waiting too long risks the customer buying elsewhere. Treat any timing as a starting point and test it, as the best interval depends on your products and customers.
Do I need consent to send abandoned cart emails in the UK?
Abandoned cart reminders are likely to count as direct marketing under PECR, so you need either consent or a valid soft opt-in. The soft opt-in can apply if you collected the email during a sale negotiation, market similar products and offered a clear opt-out at collection and in every email. Check the ICO’s current guidance.
Should abandoned cart emails include a discount code?
Not by default. Leading with a discount teaches shoppers to abandon baskets on purpose and reduces margin on orders that would have completed anyway. Start with a reminder and reassurance, then consider a modest or non-price incentive in a later email for selected customers or baskets, and test whether it adds incremental sales.
Why are my abandoned cart emails not sending?
Usually the email platform cannot identify the shopper or is not receiving cart events. Check that the store integration is active, that email is collected early in checkout, that tracking recognises returning subscribers and that the flow is switched on. Also check exit conditions and filters that may be excluding more people than intended.
