What We’re Seeing

U.S. Opt-Out vs. EU Opt-In

In the United States, privacy laws like CCPA, CPRA and others require that businesses provide consumers with a clear and accessible way to opt out of certain types of data collection, such as the sale or sharing of personal information. These laws do not prohibit tracking by default but they do require honoring opt-out requests when made. 

This differs significantly from Europe’s GDPR and similar privacy frameworks, which require business to obtain explicit opt-in consent before tracking technologies like cookies. In practice, this means that in the EU consent must be granted before any tracking occurs, whereas in the U.S., businesses may collect certain data unless a user actively opts out. 

CMPs and Misconfiguration

To manage these choices, many retailers deploy Consent Management Platforms (CMPs) that display cookie banners and record user preferences. CMPs are designed to accommodate global regulations, but we continue to see instances where they treat U.S. visitors like EU visitors, accidentally blocking all cookies until a shopper explicitly opts in. This misconfiguration is essentially applying a GDPR opt-in model on U.S. traffic, despite U.S. laws not requiring it. In effect, some brands are needlessly turning off their own data collection for American shoppers. Not only is this not required from a legal standpoint, a CMP misconfigured in this manner can severely undermine marketing efforts.

Why is this happening? In some cases, companies adopt a one-size-fits-all consent approach built around the strictest regulations globally. In others, teams are overly cautious or simply unaware that U.S. state laws permit an opt-out framework. The result is that important first-party cookies and tags get blocked by default when they don’t have to be. It’s worth emphasizing that all current U.S. state privacy laws are opt-out laws, tracking can be on by default if an opt-out mechanism is provided. Therefore, a CMP that requires opt-in for U.S. users is overreaching. In fact, Bluecore’s internal guidance notes that if a retailer’s CMP is blocking cookies in the U.S. unless a user opts in, that CMP is misconfigured under U.S. standards.

The Stakes for Retail Marketers

Misconfiguring consent doesn’t just present a compliance nuance, it directly impacts marketing performance and customer experience. By needlessly turning off tracking, retailers are effectively flying blind with a portion of their audience. Behavioral data used for personalization disappears, campaign attribution becomes muddled, and triggered communications fail to send. In a world where personalization drives relevance (and relevance drives conversions), blocking your own ability to recognize shoppers can quietly erode your results. 

Observed Impact of Misconfigured Consent

When a CMP is set to opt-in by default in the U.S., the performance consequences can be significant. Based on what we’ve observed across retail brands, a misconfigured consent platform can lead to:

• Analytics Data Gaps: Important site metrics go missing. For example, if analytics cookies are blocked, retailers lose session data in Google Analytics or Adobe Analytics, leaving blind spots in understanding shopper behavior. This makes it difficult to know how visitors arrived at the site or what paths they took, undermining data-driven decision making.
• Misleading Channel Attribution: Marketing reports become skewed. When tracking is suppressed, sales and traffic often get over-attributed to the “Direct” channel (as if customers magically arrived with no referral) and under-attributed to channels like Paid Search, Email, or Social that actually drove those visits. In essence, your attribution modeling breaks, paid and owned media look less effective than they really are, because the CMP prevented those channels from getting credit for the conversions they generated.
• Fewer Known Shoppers (Lower ID Rate): If your site can’t drop first-party identification cookies, you will recognize far fewer returning visitors. In Bluecore’s terms, the ID rate, the percentage of shoppers you can identify across sessions, goes down. A fragmented device graph means many shoppers remain anonymous ghost visitors. This shrinks your reachable audience pools for personalization and retargeting. In practical terms, your emails and ads are being triggered to a smaller fraction of interested shoppers than they could be.
• Loss of Triggered Messages: A lower ID rate leads directly to a drop in triggered customer messages. Think of all the high-intent signals your shoppers generate, product browses, cart additions, abandonment events. If your site cannot recognize the user or record the event due to blocked scripts, your system can’t send a follow-up browse abandonment or cart abandonment email to that shopper. We’ve seen cases where misconfigured consent led to fewer abandoned cart emails being sent, simply because the site treated known customers as “new” every time. Fewer triggered messages mean lost revenue, since these one-to-one emails and texts are often the highest converters.
• Extended Recovery Time: Perhaps most painful, the damage isn’t easily or quickly fixed. Many CMPs, once a user opts out (or is defaulted to opt-out), will remember that preference for months. Even after you correct a CMP setting, those users who were opted-out by default may remain untrackable until their consent choice expires or is reset. This creates a 6–12 month lag in regaining your full audience tracking. In other words, a misconfiguration today can continue to haunt your metrics well into next year. Marketing teams need to be prepared for a long tail of suppressed data even after resolving the issue.

Overall, these impacts combine to hurt the core metrics retail marketers care about. Fewer known shoppers and fewer triggered messages translate to less personalization, and personalization is proven to drive better engagement (higher inbox placement, opens, clicks, and conversions). Misconfigured consent means you could be paying for media and losing sales that you can’t even see or attribute properly, all while delivering a more generic experience to customers. It’s a lose-lose for both marketer and shopper.

How Leading Brands Handle Consent

The good news is that many retail brands have found a middle ground: ensuring they comply with privacy laws while still preserving marketing performance. The common thread is aligning consent practices to the U.S. opt-out framework. Here’s how leading retailers are approaching consent management in the U.S.:

• Default-On Tracking with Clear Opt-Out: Rather than showing a pop-up that defaults to “no tracking,” these brands load essential tracking by default for U.S. visitors. They provide a prominent, easy-to-find opt-out link or preferences panel for those who wish to disable certain cookie categories. 
• Transparent Cookie Categories: Top retailers are careful to maintain transparency about what each cookie does. Their CMP interfaces list categories like Strictly Necessary, Functional, Performance, and Advertising (or similar), with plain-language descriptions. This way, consumers who do choose to manage cookies can make informed decisions. 
• Accurate Use of “Strictly Necessary”: A critical best practice is not misclassifying cookies. Leading brands resist any temptation to lump marketing or analytics trackers into the “Strictly Necessary” category. They only label truly essential site cookies (like those for cart functionality or login sessions) as necessary. Everything else is categorized properly (e.g. analytics as Performance, Bluecore or email cookies as Functional/Marketing). The takeaway: play by the rules, don’t try to hide trackers under false labels.
• Regional Consent Logic: Finally, sophisticated brands configure their CMPs to adapt based on the user’s location. For shoppers in Europe or other opt-in jurisdictions, the CMP will present a true opt-in (no cookies dropped until consent). But for shoppers in U.S. states, the CMP follows opt-out rules, cookies start enabled, with the option to turn them off. This regional segmentation is often done via geolocation or site settings that deploy different consent experiences by region or by law. It ensures compliance where stricter laws apply, while maximizing data capture where it’s allowed. If your CMP treats every visitor the same regardless of location, you may be either risking non-compliance (if you’re too lax in a strict region) or risking performance (if you’re too strict in a lax region). Leading retailers solve this by tailoring consent strategy to the legal context.

By implementing the practices above, retailers can respect consumers’ rights and keep their data streams flowing. Remember, the spirit of U.S. law is to give consumers control if they want it. Most shoppers simply accept the default, so the default matters greatly. 

What’s Next in the Privacy Landscape

Even as retailers adjust to the current state-by-state rules, the privacy landscape continues to evolve. Global Privacy Control (GPC) is one of the next big shifts on the horizon. GPC is essentially a universal “Do Not Track” signal that a user can set once in their browser, which then communicates their opt-out preference to every site they visit. Initially championed by privacy-focused browsers like DuckDuckGo, Firefox, and Brave, GPC is now gaining broader traction due to new laws in the U.S.

Here’s what’s changing with GPC and other privacy trends:

• More States Requiring Global Opt-Out Signals: Two states, Colorado and Texas, already require companies to honor GPC signals as part of their privacy statutes. In these states, if a user’s browser sends a GPC signal, your site is obliged to treat that as an opt-out (just as if they had clicked “do not sell my info” on your site). More significantly,  California passed a new law, California Assembly Bill 566 (AB 566), “The California Opt Me Out Act”, in October 2025 that will turbocharge GPC’s adoption. This law requires all major web browsers and mobile operating systems (yes, that includes Google Chrome and Apple’s Safari, which together dominate the market) to provide a built-in global opt-out setting by the start of 2027. Enforcement in California begins January 1, 2027, meaning by New Year’s Day, browsers are expected to have this feature live. The upshot: GPC is moving from a niche feature to a standard element of web browsing for millions of consumers. We anticipate that other states with privacy laws will update their regulations to explicitly recognize and require honoring GPC signals as well, further solidifying a de facto national standard.
• CMPs Adapting to GPC: As GPC signals become widespread, Consent Management Platforms will evolve to handle them automatically. We expect CMP providers to release updates that listen for the browser’s GPC signal and interpret it as a valid opt-out without the user having to click anything on the site. For retailers, this will be helpful, your CMP will likely do the heavy lifting to comply with these global signals. However, it’s important to stay on top of your CMP updates and configurations. When GPC goes mainstream, you’ll want to ensure that a user’s “Do Not Track” preference (set in their browser settings) is indeed being honored on your website. It’s wise to check with your CMP vendor about their roadmap for GPC support if you haven’t already.
• Continued Emphasis on Opt-Out Compliance: The broader pattern in the U.S. is reinforcing the opt-out paradigm, but making it easier for consumers to exercise that opt-out. We likely won’t see a shift to opt-in laws nationwide in the immediate future; instead, we’ll see stronger enforcement of opt-out rights and more user-friendly mechanisms (like GPC) to assert those rights. For retail marketers, this means our default data collection stance can remain fairly robust, but we must be ready to instantly cut off tracking for any user who signals they don’t want it. That puts a premium on having flexible systems that can adjust per user preference in real time.

Looking ahead, the retailers who succeed will be those who can seamlessly integrate these emerging privacy tools without sacrificing personalization. Imagine a future where a significant chunk of your visitors arrive with a GPC opt-out signal already on – will your site and marketing programs gracefully degrade (e.g. still show generic content, still attribute that visit properly as, say, “Paid Search”)? Planning for that now will save headaches later. And as always, keep an eye on the legal landscape: privacy requirements tend to ratchet up over time, not loosen. Being proactive will ensure you’re not caught off guard.

Tools to Know for Privacy-Friendly Tracking

Staying ahead of privacy trends isn’t just about policy, it’s also about leveraging technology to balance compliance and insight. Here are key tools and approaches every retail marketer should know about:

• Consent Mode in Analytics: “Consent Mode” is a feature offered by major analytics platforms (like Google Analytics 4 and Adobe Analytics) that helps you gather some data even before a user has given full cookie consent. In essence, Consent Mode allows your tracking tags to send cookieless pings, very basic, non-identifying data hits, to your analytics platform when a user has not consented to cookies. These pings do not set or read cookies, so they respect the user’s choice, but they can still capture high-level information such as the fact that a visit occurred and what source/UTM brought the visitor to the site. Critically, if the user later consents and allows cookies, those earlier pings can be stitched together with the user’s subsequent activity, giving you a more complete picture of the customer journey. Enabling Consent Mode is typically as simple as toggling a setting or adding a configuration in your tag manager or analytics admin. It ensures you preserve attribution data (for example, knowing that a user came from a “Spring Sale Email” or a Google Ads click) even if that user hasn’t accepted cookies yet. This way, marketing teams can still gauge campaign effectiveness in aggregate, without violating individual consent choices. 
  • In short, Consent Mode is a must-know tool because it offers a graceful fallback: respectful of privacy, yet still feeding your analytics with the essential signals needed for optimization.

• Stay Informed on CMP Features: Make it a priority to regularly check what new features your Consent Management Platform offers. As discussed, CMPs are rolling out capabilities to handle signals like GPC automatically. They may also offer more granular controls, better UX for consumers, or integrations with your marketing stack. The landscape is moving fast; the best retailers treat their CMP not as a “set it and forget it” tool, but as an evolving part of the tech stack that needs periodic tuning. Assign an owner on your team to monitor privacy-tech updates. Many CMPs maintain newsletters or release notes, subscribe to those. Knowing about a new feature (say, an API that lets you sync consent choices with your email platform, or a feature to A/B test your cookie banner design) could give you a competitive edge in keeping consent rates high without hurting data collection.
• First-Party Data Strategies: Lastly, continue investing in a robust first-party data strategy. The writing is on the wall that third-party cookies are going away, and even first-party data collection will happen on tighter terms. Retailers who cultivate direct customer relationships, through loyalty programs, membership, subscriptions, etc., have more leeway to gather data with user trust. When a shopper is logged in or has a clear relationship with your brand, you can often track preferences in a consent-compliant way (for example, storing their email interactions or purchase history tied to their account, which isn’t reliant on cookies at all). While this isn’t a “tool” in the sense of a software feature, it is a strategy enabled by tools like customer data platforms and loyalty apps. By strengthening direct ties to customers, you mitigate the loss of cookie data. So think of building up your own databases of consented customer information as a long-term tool in your privacy toolkit. That way, even as browsers and laws limit passive tracking, you can continue delivering personalization based on data customers have willingly shared with you through their profile and actions.

In summary, a combination of smart platform features (like Consent Mode) and forward-thinking data strategy will help you navigate the technical side of privacy. These tools ensure that even as individual consumers exercise more rights over tracking, your marketing engine doesn’t stall out, it adapts and keeps providing value to both your team and your shoppers.

Conclusion

The era of unchecked data collection is over, but that doesn’t mean retail marketers must sacrifice personalization or performance. The key is understanding and embracing the opt-out-first landscape of U.S. privacy law. Nearly all stateside legislation allows you to collect data by default, so long as you respect the customer’s choice to opt out. By configuring your consent management properly, you avoid the self-inflicted wounds of lost analytics, fragmented user identification, and suppressed campaigns. In our observations, many CMP configurations today unintentionally go too far, diminishing marketing results without any legal benefit. The retailers that get it right are those who put relevance first, they find ways to honor privacy while still delivering the tailored experiences shoppers expect.

As you move forward, keep an eye on emerging regulations and browser features like Global Privacy Control, and leverage tools like Consent Mode to maintain insight into your marketing efforts. Privacy and personalization need not be at odds. By adopting best practices now, default-on with opt-out, truthful cookie categorization, regional consent logic, and new tech tools, you can build a relevance-first inbox and on-site experience that thrives even in a privacy-conscious world. The landscape will continue to evolve, but with the right approach, you’ll stay ahead of the curve. In the end, doing right by your customers’ preferences isn’t just about avoiding fines; it’s about building trust. And trust, paired with smart marketing, is what keeps shoppers coming back in the long run.
