Lapsed is the status a customer relationship management (CRM) system gives to someone who has bought, subscribed or donated before but has not done so again within a defined period. It exists because most commerce has no exit event. A subscriber cancels; a shopper simply stops, and the database has to decide when silence counts as departure. That decision, usually a single date rule, then governs which messages the person receives, which advertising audiences the record is uploaded to and how long the business may keep it.

How a CRM decides someone has lapsed

The working field is the date of last purchase. A rule flips the record once the gap since then passes a threshold, measured by calendar period or on a rolling basis. Fundraising databases formalised the calendar version. Salesforce's Nonprofit Success Pack ships an Account LYBUNT report, short for "last year but unfortunately not this", which returns every account that gave more than $0 last year and $0 this year. SYBUNT, "some year", reaches further back. The two methods disagree at the edges: a donor who last gave in December appears on a LYBUNT report run in February, yet is only two months into a rolling 12-month window.

Outside fundraising, the threshold is often a manager's judgement. In a 2008 Journal of Marketing study, Markus Wuebben and Florian von Wangenheim found managers at an airline and an apparel retailer treating customers as inactive after nine months without a purchase. That hiatus heuristic often classified customers as accurately as the probabilistic models built for the job. Category moves the number. A measurement framework from In-Store Marketplace and Catalyst Media Consulting segments shoppers as loyal, occasional, lapsed and new, noting that lapsed means something different for a dairy brand than for an over-the-counter medicine.

Predictive CRMs replace the fixed cutoff with a score. Klaviyo, which repositioned itself as a business-to-consumer (B2C) CRM in February 2025, defines churn risk as the probability that a customer will not buy in the next 90 days, banded low below 33%, medium up to 66% and high above that. Its predictions switch on only once at least 500 customers have placed orders, with 180 days of order history, orders in the last 30 days and some customers on three or more purchases.

Lifecycle fields resist the concept. HubSpot's default lifecycle stage property, whose eight values run from Subscriber through Customer to Evangelist and Other, can only be moved forward by imports, forms, the application programming interface (API), the Salesforce integration and workflows. Stepping a customer back means clearing the field first, or adding a custom stage, which requires Super Admin rights. The IAB Australia Retail Media Council's blueprint, by contrast, names acquisition, growth, maturity and lapse as lifecycle stages.

From CRM record to ad audience

Activation follows the sequence PPC Land's CRM explainer describes: export, normalise, hash and upload, after which the match rate decides how many records a platform recognises.

Google's retention goal depends entirely on that export. Its Re-engagement setting, described as "Bid higher for lapsed customers than existing ones", runs only in Performance Max with value-based bidding and a purchase conversion goal, according to Google. The business defines lapsed, and Google does not detect it: lapsed lists must arrive through Customer Match, which matches hashed customer lists to signed-in accounts, via customer data platform (CDP) and CRM connectors, the API or direct upload. Auto-detection and tag-based lists do not qualify. The Google Ads API labels lists by customer type, and a DISENGAGED_CUSTOMERS list cannot also be tagged CART_ABANDONERS. Its CUSTOMER_RETENTION goal adds conversion value for lapsed buyers, 50 in Google's code sample, while, as of October 2026, the "Only bid for lapsed customers" option needs an allowlist.

Time limits sit underneath. Google's auto-detection builds its existing-customer list from up to 540 days of tracked purchases, and Customer Match membership has been capped at 540 days since April 7, 2025. A buyer whose last order is older falls out of the detected list and stays on an uploaded one only if the CRM refreshes it. A return purchase can then register as new.

Other platforms draw their own lines. Amazon counts a shopper as new to brand after no conversion with that brand in 12 months. Its Ads Data Manager takes each record with the advertiser's customer ID, hashed identifiers and consent. Meta's targeted offers, introduced for US merchants in 2025, defined new customers as those who had not bought within two years. A customer whose last order was 14 months ago can therefore be lapsed in a CRM, new to brand at Amazon and existing at Google and Meta on the same day.

Origin and evolution

The word came from memberships, insurance and subscriptions, where a policy lapses when it is not renewed. The modelling problem was formalised in 1987, when David Schmittlein, Donald Morrison and Richard Colombo published the Pareto/NBD model, which estimates from the number and timing of past purchases the probability that a customer is still active.

Google added a new customer acquisition goal to Performance Max in 2022, opened a retention beta in 2024 and, on April 8, 2025, introduced Win-Back and High Value Win-Back modes. Its own announcement said retention goals were now available to all advertisers. As of October 2026 the help pages call the modes Re-engagement and High Value Re-engagement and add a Loyalty Program Members setting, though one page still labels both lapsed modes beta. Version 25 of the Google Ads API, released on July 22, 2026, removed the older lifecycle goal resources.

Why it matters for marketers

Lapsed customers cost little to reach, since their details are already on file. Bringing them back is harder. RevenueCat's 2026 subscription report, drawn from more than 115,000 apps, put annual-plan reactivation at about 5% and monthly reactivation at 20% within a year. Those company figures held across price tiers and regions, suggesting the billing plan shapes the returning pool more than any offer.

Retailers now sell lapsed segments built from their own customer files. THG opened lapsed audiences from Cult Beauty and LOOKFANTASTIC on The Trade Desk on February 16, 2026. The term also works in business-to-business sales. On August 6, 2026, The Trade Desk said a growth team partly focused on winning back lapsed customers had grown its book by more than 250%, without disclosing the base.

Regulators write lapse rules of their own. France's data protection authority, the Commission nationale de l'informatique et des libertes (CNIL), lets businesses keep customer data used for prospecting during the relationship and for three years after it ends, counted from the last purchase or contact. For online accounts that go dormant, the CNIL recommends deletion two years after the person's last action. In the UK, the soft opt-in under the Privacy and Electronic Communications Regulations (PECR) allows email to existing customers who bought similar products and were offered an opt-out at collection and in every message. The Information Commissioner's Office (ICO) frames it around a recent purchase but sets no number of months, so a CRM's lapse threshold doubles as a legal judgement.

Where it breaks down

The cutoff is a guess. In non-contractual retail, a lapsed buyer and a slow one look identical. Byron Sharp and colleagues at the Ehrenberg-Bass Institute argued in a 2012 Journal of Advertising Research paper that apparent defections are typically light customers who do not buy every year. A win-back campaign may then pay to reach people who were returning anyway. The IAB Australia blueprint measures win-back against control groups, the comparison that separates the two.

Definitions also collide in reporting. A customer the CRM records as won back after 14 months can appear in Amazon's new-to-brand count. IAB Europe's commerce standards let networks report new-to-brand against five purchase-cycle buckets, from up to two weeks to 52 weeks or more, so two retailers can classify the same returning shopper differently.

Lapsed lists decay. Klaviyo suppresses a profile after one hard bounce, or after seven consecutive soft bounces within two years. Because suppression is triggered by sending, a lapsed segment left unmailed is not cleaned until a win-back campaign goes out. Predictions are weakest where they are most needed: when a customer's orders show no pattern, Klaviyo bases the expected next order date on how other customers behave.

Not the same as

Churn is the broader rate of customer loss; where a contract exists it is an observed cancellation. Lapsed describes a single record whose silence has passed a threshold.

At-risk customers have not yet crossed that threshold; Klaviyo's churn score exists to find them before they do.

New-to-brand is a platform measurement label. A lapsed customer can qualify for it after 12 months at Amazon or, under IAB Europe's travel draft, as new to advertiser after three years.

Cart abandoners have never completed a purchase, which is why Google's API keeps them off disengaged-customer lists.

The word carries an unrelated meaning in ad tech too: certifications that lapse, as Google's and The Trade Desk's Trustworthy Accountability Group (TAG) seals did in 2026.

Recent developments

Retail media networks have started modelling lapse rather than waiting for it. Sam's Club Connect launched targeting for lapsed or staggered buyers on September 17, 2026. The same day, IAB Europe opened a travel addendum that would treat a traveller as new to an advertiser only after three years without a purchase; comments close on October 23, 2026. Google has required Customer Match uploads to pass through its Data Manager API since April 1, 2026, the route lapsed lists now take.

Summary

Who: Retention, lifecycle and CRM teams at brands, retailers, subscription businesses and charities set and apply the status; CRM and engagement vendors such as Salesforce, HubSpot and Klaviyo encode it; ad platforms including Google, Amazon and Meta consume lapsed lists under their own definitions; retailers such as THG and Sam's Club sell lapsed segments; and regulators such as the CNIL and the UK's ICO limit how long former customers can be marketed to.

What: A customer status, recorded in a CRM, for someone who bought, subscribed or donated before but not within a defined window. It is set by a fixed recency rule, a calendar comparison such as LYBUNT, or a predictive score such as Klaviyo's 90-day churn risk.

When: The concept came from subscriptions and fundraising, was modelled in 1987 and tested against managerial rules of thumb in 2008. Ad platforms built lapsed bidding modes between 2024 and 2026, as Google capped Customer Match membership at 540 days from April 7, 2025.

Where: In CRM, customer data platform and email systems, in the hashed lists those systems upload to Google Customer Match, Amazon Ads Data Manager and Meta Custom Audiences, in retail media audience catalogues, and in the measurement standards that decide when a returning customer counts as new.

Why: Most purchases have no cancellation event, so a business must choose when silence means departure. That choice drives win-back spending, bidding values, new-customer reporting and data retention, and because every system draws the line differently, the same person can be lapsed, new and existing at once.
