Article summary

TL;DR

Abandoned cart recovery is the process of bringing back a shopper who left items in an online cart or checkout without buying. Stores do it with email, text, push or retargeting ads, sent with the shopper's consent where the law requires it. It is different from recovering a failed payment, which is fixed with retries and another payment method.

Recovery starts after the shopper leaves. Prevention, fixing the checkout so fewer people leave, is a separate job.
A shopper who left and a payment that failed need different fixes: a reminder for the first, a retry or another payment method for the second.
Each channel has its own consent rule. In the US, marketing texts sent with an autodialer need prior express written consent; email needs an ad disclosure, a postal address and a working opt-out.
Shopify marks a checkout as recovered even when the shopper comes back on their own. Use a holdout group to count the orders your reminders actually add.

What is abandoned cart recovery?

Abandoned cart recovery is what a store does after a shopper leaves, to bring that shopper back to the same order. It starts where cart abandonment ends: abandonment is the exit, recovery is the follow-up. Making the checkout better so fewer people leave is prevention, a separate job covered in how to reduce cart abandonment.

Recovery needs a way to reach the shopper. An email address or phone number typed at checkout lets you send a message. A cookie or pixel lets you show an ad. That is why Shopify only lists a checkout as abandoned once the customer has entered contact information and the checkout "remains incomplete for more than ten minutes".1

Cart vs. checkout recovery. Klaviyo separates them by trigger: a flow on Added to Cart "targets abandoned carts", a flow on Started Checkout "targets abandoned checkouts", and it recommends running both.3 Checkout recovery reaches fewer people, but people closer to buying.

Shopper recovery vs. payment recovery

Some carts are not abandoned at all: the shopper clicked pay and the payment failed. In your analytics, both look like an order that never happened. The fixes have nothing in common.

	Shopper who left	Payment that failed
What happened	Closed the tab, compared prices, got distracted	The issuer declined, or 3D Secure was not completed
Fix	A reminder by email, text, push or ad	Smart retry of soft declines, another payment method, a second processor through cascading payments
What not to do	Message shoppers you have no right to contact	Retry a hard decline such as a lost or stolen card
Who owns it	Marketing and CRM	Payments

Join your processor's payment attempts to checkout sessions before you send any reminder. A shopper whose card was declined needs a link to pay another way, not a "you forgot something" email.

Channel	How it reaches the shopper	Consent rule
Email	Address typed at checkout	US: CAN-SPAM needs no prior consent, but a marketing email must say it is an ad, include a valid postal address and an opt-out honored within 10 business days.5 Transactional status covers only a transaction "the recipient already has agreed to", which an unfinished checkout has not reached
Text (SMS)	Phone number typed at checkout	US: marketing texts sent with an autodialer need prior express written consent, signed (electronic signatures count), naming the number, with a statement that consent is not a condition of purchase.6 STOP, QUIT, END, REVOKE, OPT OUT, CANCEL or UNSUBSCRIBE revokes it
Push	Browser or app notification	Only after the shopper grants permission: until then, the browser acts as if permission was denied.8
Retargeting ads	Cookie or pixel on the store	UK: non-essential cookies need consent, with "particular care" for behavioural tracking (ICO).7
On-site (saved cart, reminder on return)	Cart cookie or customer account	UK: a cookie that remembers "the goods a user wishes to buy" is unlikely to need consent (ICO).7

For EU and UK email rules, including the ICO's soft opt-in, see cart abandonment. Texting details are in SMS marketing for ecommerce. This is not legal advice.

How platforms trigger it

The shopper leaves contact details and starts checkout. Without them, there is no one to email.
Shopify waits 10 minutes, then lists the checkout as abandoned. Recovery works only on the Online Store and Buy Button channels, and abandoned checkouts are deleted after three months.1
The first reminder goes out. Shopify's automation is "only sent to customers that are subscribed to email marketing" by default; a second automation defaults to a 10-hour wait.2 Klaviyo's pre-built flows wait 4 hours.3
The flow stops on purchase. Klaviyo recommends the filter "Placed Order zero times since starting this flow", and tells customers in regions with data protection laws to consult their legal team before going live.3

Timing, message content and discounts are covered in how to reduce cart abandonment.

How to measure recovered revenue

An illustrative formula, not an industry standard:

Recovery rate = recovered orders ÷ recoverable carts × 100, counted within a fixed attribution window.

Recoverable carts: abandoned carts you can legally contact, with contact details and, where needed, consent.
Recovered orders: orders placed from those carts within the window after a reminder.
Recovered revenue: the value of those orders.

1,000 checkouts are abandoned.
600 of them have an email address with marketing consent: these are the recoverable carts.
48 orders come back within 5 days of a reminder click: a recovery rate of 48 ÷ 600 = 8%.
At a $70 average order, that is $3,360 in recovered revenue.

Illustrative example: one store, one month.

Two caveats change the reading. Shopify counts a checkout as recovered once the customer completes the order, whether through the email link or on their own.1 Klaviyo credits the last message clicked or opened, with default windows of 5 days for email clicks and 5 days for email opens.4 Both count some orders that would have come back anyway.

To get the number your reminders actually add, keep a random holdout group of recoverable carts that receives nothing. Your incremental recovery rate is the messaged group's rate minus the holdout's rate. To measure abandonment itself, the formulas are in checkout abandonment rate.

How Tagada helps

Recover the shopper and the payment

Tagada's checkout supports one-click upsells, order bumps, A/B tests, and Apple Pay and Google Pay. Server-side tracking sends checkout events to Meta, Google and TikTok, so a blocked browser tag doesn't hide a real order. Payments route across Stripe, Adyen and Tagada's own TagadaPay processor with one logic, with a cascade on decline, and subscriptions get automatic retries and recoveries when a payment fails.

Frequently asked questions

What is abandoned cart recovery?

It is the follow-up a store sends after a shopper leaves a cart or checkout without buying: an email, a text, a push notification or a retargeting ad that brings the shopper back to the same cart. It only works if the store can reach the shopper, through contact details typed at checkout or an ad cookie, and has the right to use them.

What is abandoned cart payment recovery?

It means recovering an order that failed at the payment step, not one the shopper walked away from. The fix is on the payment side: retry soft declines where the decline code allows it, offer another payment method, or route the payment to a second processor. Never retry a hard decline such as a lost or stolen card.

Do I need consent to send abandoned cart texts in the US?

For marketing texts sent with an autodialer, yes. The FCC's TCPA rules require prior express written consent: a signed agreement, electronic signatures included, that names the phone number and says consent is not a condition of purchase. A reply such as STOP, QUIT or UNSUBSCRIBE revokes it and must be honored within ten business days at most.

What is a good abandoned cart recovery rate?

No card network, regulator or platform documentation we read publishes a benchmark, and vendor figures use different definitions. Measure your own: recovered orders divided by recoverable carts, within a fixed attribution window, compared with a holdout group that got no reminder.

What are the advantages of cart recovery?

It reaches people who already chose a product and typed their contact details, so the message is relevant and the cart can be restored in one click. It also tells you where shoppers stop: replies, clicks and the step they return to point at the objection your checkout fails to answer.
