Here’s the math most ecommerce brands don’t talk about: 97% of your website visitors leave without ever identifying themselves.
Your pop-up is working fine. Your conversion rate probably sits around 3%. The problem isn’t your strategy. It’s that conversion rates have a ceiling. And if you’re not capturing the other 97%, you’re leaving revenue on the table.
In a recent webinar with Tom Rowe, SVP of Sales & Marketing at OpenSend, we broke down how identity resolution has evolved from a “nice-to-have” to table stakes for scaling ecommerce brands. What started as a novel category three years ago is now a fundamental piece of the growth stack, and the brands that ignore it are quietly becoming less competitive.
What Identity Resolution Actually Does (and Why It Matters Now)
Identity resolution provides clarity into who your anonymous shoppers are, then passes that information into the places where you engage customers: your ESP, your ad channels, your retargeting flows.
The premise is simple: you’ve already paid to get traffic to your site. Why not capture value from visitors who don’t convert immediately?
Traditional first-party opt-ins – pop-ups, welcome offers, email capture – remain the gold standard. But they plateau. Even strong brands max out around 3-5% opt-in rates. Identity resolution doesn’t replace that strategy. It supplements it by identifying high-intent anonymous visitors and turning them into engageable contacts.
The result? Brands typically double their list growth. If you’re capturing 10,000 first-party opt-ins per month, identity resolution can add another 10,000-15,000 high-intent profiles on top of that.
Two Types of Anonymous Traffic (and Why That Distinction Matters)
Not all anonymous traffic is created equal. Understanding the difference changes how you deploy identity resolution tools.
Net new anonymous visitors have never interacted with your brand. They’ve never opted in, never made a purchase. These are top-of-funnel prospects who showed enough intent to warrant follow-up, but didn’t convert on their first visit.
Returning users your ESP is missing are customers or subscribers browsing on a new device, a cookie-less browser (hello, iPhone users), or simply not logged in. Your ESP thinks they’re anonymous, but they’re actually known users. Identity resolution reconnects those sessions to existing profiles.
This is why identity resolution sits at both ends of the funnel. It’s a list growth tool for new prospects and a retention tool for existing customers whose sessions are being missed.
The Biggest Mistakes Brands Make with Identity Resolution
Mistake #1: Not Using It at All
Three years ago, identity resolution felt like a gray area. Brands hesitated to “expose” anonymous visitors. That reluctance is now a strategic mistake.
Website traffic isn’t cheap. You’re paying for it in CPMs or SEO investments. If you’re not capturing identities from high-intent visitors, your CAC increases, and your email list stagnates.
Mistake #2: Using It Recklessly
On the other end of the spectrum, brands discover identity resolution and immediately try to identify everyone. That’s a deliverability disaster waiting to happen.
If someone fat-fingers an Instagram ad, lands on your site for five seconds, and bounces, you should not be identifying them. Low-intent visitors are unlikely to convert from retargeting, and worse, they’ll report you as spam or unsubscribe. Your email program takes the hit.
The rule: Identity resolution should focus on high-intent shoppers. Users who spend meaningful time on site, visit multiple pages, engage with product content. Those are the people worth re-engaging.
Real Results: What Happens When You Get It Right
Made In Cookware, a direct-to-consumer brand selling premium pots and pans, implemented identity resolution with intent thresholds tailored to their high AOV product ($350-$400 average cart).
They set parameters to capture users who spent 90+ seconds on site and visited 3+ pages, excluding low-intent pages like warranty info and customer service.
In the first month:
- 70,000 new incremental users identified
- $700,000 in revenue from visitors who otherwise would have abandoned
- Hundreds of thousands of dollars directly attributable to retargeting emails that were only possible because identity resolution passed profiles to Klaviyo
The ROI was immediate. No 60-day wait. By day 14, the math was clear.
What’s Changed: New Capabilities Beyond Email Capture
Identity resolution started as a linear use case: identify an anonymous visitor, send them an email. The category has matured significantly.
Data enrichment now includes demographic insights pulled from identity graphs. Brands can access aggregated data on household income, age, gender, number of children, housing density, and information that informs product roadmaps, media buying, and customer segmentation strategies.
Cross-channel activation means identities aren’t just passed to ESPs. Ad channels benefit too. Identity graphs often contain multiple email addresses for a single user (the one they use now vs. the one they signed up for Facebook with a decade ago). Passing all associated emails increases match rates and extends your ability to retarget beyond finite cookie windows.
Direct mail is making a comeback as CPMs rise during peak seasons. Identity resolution providers maintain home addresses, enabling brands to engage high-intent visitors through physical mail when digital channels saturate.
Compliance and Deliverability: The Questions You Should Be Asking
If you’re hesitant about identity resolution, compliance, and deliverability concerns are probably why. Here’s what matters:
How is opt-in consent captured?
Reputable providers build proprietary identity graphs through partner publishing networks. When a user inputs their email on a partner site (a quiz platform, content site, etc.), opt-in consent is passed through to partners, including the brands using identity resolution tools.
Providers should maintain records of when and where consent was captured. Full CAN-SPAM, CCPA, and California Drop and Delete Act compliance is non-negotiable.
What happens to your customer data?
Some identity resolution providers ingest the customer data you pass through your ESP integrations and use it to build their own identity graphs. That creates a network effect, but it also means your customer data is being mined to benefit other brands.
Other providers, including OpenSend, keep customer data separate. Their identity graph is built and maintained entirely outside of ESP integrations. If data privacy matters to your brand, this distinction is worth asking about.
How is the identity graph maintained?
Weekly updates should strip out known spam reporters, international addresses, and users who haven’t engaged with brand emails in 60+ days. This maintenance keeps spam rates below 0.3% and unsubscribe rates below 5%, well within ESP benchmarks.
If a provider can’t articulate how they maintain data quality, that’s a red flag.
When Identity Resolution Doesn’t Make Sense
Not every brand is a fit for identity resolution. Two scenarios where it typically doesn’t work:
Brand new brands shouldn’t lean on identity resolution to build their entire email program. You need a foundation of first-party opt-ins first. Identity resolution should represent roughly 10% of your total promotional email volume, not the majority.
Brands heavily dependent on Amazon or brick-and-mortar retail may see diminished returns. If most of your traffic is researching on your site but converting elsewhere (Amazon, Target, etc.), identity resolution can still work, but expect longer time-to-conversion. It might take until a second purchase to pull that customer back to your direct channel.
First-Party Opt-Ins Still Win (But Identity Resolution Closes the Gap)
One of the most common questions: Should identity resolution change how we think about our pop-up strategy?
The answer is no.
First-party opt-ins remain the best way to grow your email list. Those users are showing the highest intent. You can email them more frequently. The relationship is stronger.
Identity resolution supplements that strategy. It doesn’t replace it. You should still optimize your welcome offers, test pop-up timing, and prioritize first-party consent capture. Identity resolution just ensures you’re not leaving 97% of your traffic behind when they don’t convert immediately.
Think of your pop-up less as a conversion tool and more as an affinity signal. How much do people like your brand enough to opt in? How compelling is your offer? Identity resolution captures the high-intent visitors who weren’t quite ready to commit, but still deserve follow-up.
What’s Next: The Category Keeps Evolving
Identity resolution has moved well beyond basic email capture. Recent advancements include:
- CDP integrations that pass anonymous event data to ad channels, increasing ROAS and solving signal loss between Shopify and platforms like Meta
- Persona-based segmentation that breaks customer bases into cohorts for lookalike audiences and product development insights
- Cross-device tracking that insulates brands from future cookie deprecation (whenever Google finally pulls that trigger)
The brands winning with identity resolution aren’t just collecting contacts. They’re enriching data, activating across channels, and asking the right compliance questions upfront.
The Bottom Line
Website traffic is expensive. CAC keeps climbing. Conversion rates plateau.
If 97% of your traffic is anonymous and you’re not capturing high-intent visitors, you’re not just leaving money on the table, you’re making acquisition harder than it needs to be.
Identity resolution has shifted from a novel tactic to table stakes. The question isn’t whether to use it. The question is how to use it strategically: with the right intent thresholds, the right compliance safeguards, and the right expectations about what it can (and can’t) do.
