TL;DR
- People-based marketing (also called identity marketing) targets known individuals using real behavioral data, rather than anonymous audience segments defined by demographics or interests.
- The core requirement: you need to know who your visitors and customers are at an individual level, not just aggregate patterns.
- For DTC brands, people-based marketing primarily operates through three channels: email (using identified contacts), paid retargeting (using first-party custom audiences), and on-site personalization (using behavioral profiles).
- Identity resolution — the process of matching anonymous visitors to known profiles — is the enabling infrastructure that makes people-based marketing possible.
- Brands implementing people-based marketing see higher conversion rates and lower acquisition costs because messaging is based on demonstrated intent rather than demographic inference.
Key Takeaways
- Traditional audience targeting uses demographic and interest proxies. People-based marketing uses actual identity and behavioral signals.
- First-party data (email addresses, purchase history, on-site behavior) is the asset that enables people-based marketing — and it belongs to you, not to ad platforms.
- Three practical tools implement people-based marketing for DTC: email platforms (Klaviyo), identity resolution tools (Attribuly), and paid media custom audiences (Meta, Google).
- The coverage gap is the main barrier: if you can only identify 14% of visitors, your people-based marketing only reaches 14% of your potential audience.
- Closing the coverage gap — from 14% to 55%+ — is the highest-leverage investment in people-based marketing infrastructure.
What is people-based marketing?
Traditional digital marketing targets audience segments: "women aged 25-34 in the US who are interested in fitness." The targeting is based on demographic and interest proxies inferred by ad platforms from aggregated behavior.
People-based marketing replaces that inference with direct identity: "Elena, who viewed your running shoes three times this week and added to cart on Tuesday." The targeting is based on what a specific, known person actually did.
This distinction matters because:
| Dimension | Segment-based | People-based |
|---|---|---|
| What you know | Demographic proxy characteristics | Actual identity and behavior |
| Message relevance | Based on inferred interest | Based on demonstrated intent |
| Channel consistency | Separate campaigns per channel | Same person reached coherently across channels |
| Waste | High — many segment members have low intent | Low — targeting confirmed intent signals |
| Data ownership | Platform-dependent | You own your first-party data |
The three channels of people-based marketing for DTC
Channel 1: Email (identity-first)
Email is inherently people-based — you send to a specific email address tied to a specific person. The challenge is that most email campaigns only reach the subscribers who are already on your list, and most visitors never become subscribers through passive means.
Identity resolution extends email's reach: by matching anonymous visitors to email addresses, you expand the population your email-based people-based marketing can reach — from form subscribers only to anyone who has visited with identifiable intent signals.
Channel 2: Paid retargeting (custom audiences)
Meta and Google allow advertisers to upload customer lists (email addresses) and create custom audiences of known individuals. Ads are then shown specifically to those people across Meta's and Google's properties.
Why people-based retargeting outperforms standard retargeting: Standard retargeting pixels show ads to anyone who triggered a pixel event — but pixel coverage has declined significantly due to iOS privacy changes and browser restrictions. Uploading a list of identified emails creates a custom audience that does not depend on pixel tracking, and reaches known high-intent individuals directly.
The multiplier effect: Every contact identified through visitor identification tools becomes part of your custom audience. More identified contacts → larger, higher-intent custom audiences → better retargeting performance.
Channel 3: On-site personalization
Using behavioral profiles tied to known identities, on-site experiences can be personalized — showing relevant products, adjusting offers, or prioritizing content based on purchase history and browsing behavior.
This requires the same identity infrastructure as email and retargeting: you need to know who the visitor is to personalize their experience.
How to implement people-based marketing for Shopify
Step 1: Build your first-party data foundation
The currency of people-based marketing is first-party data — information you've collected directly from your customers and website visitors with appropriate consent.
For Shopify stores:
- Email list (from popups, checkout, post-purchase)
- Purchase history (from Shopify)
- On-site behavioral events (from Klaviyo or server-side tracking)
- Identified anonymous visitor data (from identity resolution tools)
Step 2: Close the identification gap
Native Klaviyo tracking captures around 14-15% of on-site behavioral events. Attribuly's identity resolution layer increases this to 55%+ — the same people-based marketing infrastructure, but reaching 3-4x more of your actual visitors.
This is the highest-leverage step: every additional identified contact expands your email reach, your custom audience size, and your retargeting pool simultaneously.
Step 3: Build behavioral triggers (not time-based sends)
People-based marketing is most powerful when messages are triggered by what a person just did, not by a scheduled calendar date.
| Behavior | Triggered message |
|---|---|
| Viewed product 3 times, no cart | Browse abandonment email |
| Added to cart, no checkout | Abandoned cart email (Email 1) |
| Started checkout, no purchase | Checkout abandonment email (Email 1 within 60 min) |
| Purchased, 30 days no return | Replenishment or cross-sell email |
| Opened email but didn't click | Follow-up with different angle |
Step 4: Sync identified contacts to paid media
Upload your identified email list to Meta and Google as custom audiences. This creates:
- Retargeting audiences of verified high-intent visitors
- Lookalike audiences modeled on your best customers
- Suppression lists (exclude recent purchasers from acquisition campaigns)
Step 5: Close the feedback loop
As identified contacts convert, send richer conversion signals back to ad platforms through server-side tracking. This improves ad platform optimization — better data in means better targeting out.
Common mistakes in people-based marketing
Mistake 1: Treating all email subscribers as equal
Not all contacts have the same intent level. A visitor who added to cart has higher intent than someone who signed up for a discount popup six months ago. People-based marketing should segment by behavioral intent, not just list membership.
Mistake 2: Stopping at email and ignoring paid retargeting
Email and retargeting are complementary channels in people-based marketing. An identified contact who doesn't open your email might see your retargeting ad. Limiting people-based marketing to email only leaves a significant complementary channel unused.
Mistake 3: Not measuring people-based reach as a separate metric
How many of your actual visitors are you reaching through people-based channels? This number — total people-based reach ÷ total visitors — is the most important metric in people-based marketing and is rarely tracked.
Mistake 4: Confusing people-based marketing with mass personalization
Adding a first name to a subject line is not people-based marketing. True people-based marketing triggers messages based on what a specific person actually did — not what a demographic segment is statistically likely to do.
