Why people leave without paying
Not every abandoned cart is a lost sale. People add items to compare prices, to save them for later or to see the delivery cost. But a good share of abandonment comes from friction in your own shop. The usual causes are:
- Delivery costs or delivery times that only appear at checkout.
- Being forced to create an account before paying.
- A long or confusing checkout form, especially on a phone.
- Their preferred payment method missing.
- Errors at the payment step, such as a failed card authentication.
- Doubts about trust: unclear returns, no contact details, no reviews.
- A slow checkout page.
Fixing these brings back sales you would never have recovered with a reminder email, so start here.
Fix the checkout first
Work through this list on your own phone, as if you were a first-time customer:
- Show delivery costs early. Put costs and delivery times on product pages or a clear delivery page, and show the total in the basket. Our guide to shipping options for UK webshops covers how to set rates that are easy to explain.
- Allow guest checkout. Offer account creation after the order, not before.
- Cut unnecessary fields. Remove anything you do not need to fulfil the order, such as company name for consumer shops or a second phone number.
- Offer the payment methods your customers expect, including wallets such as Apple Pay and Google Pay for mobile buyers. See WooCommerce payment options in the UK.
- Make trust visible. Link your returns policy near the payment button, show your contact details, and display genuine reviews where you have them.
- Check speed. The checkout cannot be cached like other pages, so a slow server or heavy plugins hit it hardest. Our guide to speeding up a WooCommerce shop explains what to look at.
- Test errors. Try a declined card, a wrong postcode and an empty required field. Error messages should say exactly what to fix.
Find out where people drop off
Guessing is less useful than looking at your own data. Useful sources include:
- Your analytics funnel from product page to basket to checkout to order received.
- Failed and pending orders in WooCommerce, which often point to payment problems.
- Your payment provider's dashboard, which shows declined and abandoned payment attempts.
- Customer messages that start with "I tried to order but".
If most people leave at the basket, look at delivery costs and trust. If they leave at the payment step, look at payment methods and errors. Bear in mind that analytics and session recording tools that use cookies need consent under UK rules, so your figures may not include every visitor.
Reminder emails: how they work
An abandoned cart plugin captures the email address a customer types at checkout and, if they do not complete the order, sends one or more reminders with a link back to their basket. A simple sequence:
- First reminder within a few hours: a plain, helpful note. "You left these in your basket" with the items, the total and a link back. Offer help in case something went wrong.
- Second reminder about a day later: answer common doubts: delivery times, returns, how to contact you.
- Optional third reminder: only if you have a reason, such as low stock. Be careful with discounts (see below).
Keep the emails short, personal and clearly from your shop. Stop the sequence immediately once the customer orders, and make it easy to opt out.
Consent and the rules
This is where many shops get it wrong. In the UK, marketing emails to individuals are covered by the Privacy and Electronic Communications Regulations (PECR) as well as data protection law. The general position is:
- You can send marketing emails to people who have given clear consent.
- The "soft opt-in" may allow marketing to people whose details you collected during a sale or negotiation for a sale, about your own similar products, provided you gave them a simple way to opt out when you collected their address and in every message.
- Your privacy notice should explain that you capture checkout details and may send reminders.
Whether a particular reminder counts as marketing, and whether the soft opt-in covers someone who never completed a purchase, depends on the details. The safest approach is to treat cart reminders as marketing: tell people at the email field that you may send a reminder, include an opt-out in every email, and respect it. The ICO's guidance on electronic marketing on ico.org.uk sets out the rules, and the law in this area has been updated, so check the current guidance or take advice.
Our guide to email marketing for small shops covers building a consented list in more detail.
Discounts, other channels and measuring results
Discounts in reminder emails can work, but they teach some customers to abandon carts on purpose and wait for a code. If you use one, keep it modest, put it in a later email rather than the first, and do not send it to the same person every time.
Other ways to bring people back include saved baskets for logged-in customers, wishlists, and advertising to past visitors. Advertising based on tracking cookies needs consent under the same UK rules, and the ICO guidance on cookies explains what that involves.
Measure what matters: recovered orders, revenue from reminders, unsubscribe rate and complaints. If unsubscribes rise, your reminders are too frequent or too pushy.
Some carts are abandoned because the customer had a question nobody answered. On Retail Web Hosting's Shop Grow plan, BonusFlow Ecommerce shows orders and order questions next to each customer's email, which makes those questions quicker to answer.
Frequently asked
Are abandoned cart emails legal in the UK?
They can be, but treat them as marketing under PECR and data protection law. Make it clear at checkout that you may send a reminder, include an opt-out in every email and check the ICO's current guidance.
How many abandoned cart emails should I send?
Two is enough for most shops: one within a few hours and one around a day later. A third only makes sense with a genuine reason, and stop the sequence as soon as the customer orders.
Should I offer a discount to recover abandoned carts?
Use discounts sparingly. They can recover some orders, but regular codes teach customers to abandon carts on purpose and wait for an offer.
