Most businesses work hard to generate leads, but what happens after those leads slip through the cracks? Visitors come to your site, maybe even fill out a form at some point—but then they disappear. You’ve already paid to acquire them once, but now they’re just anonymous traffic again.
What if you could identify those visitors when they return—and re-engage them automatically?
This is exactly what SendLeads makes possible. Using a simple identity resolution pixel, we help businesses recognize anonymous traffic, match it back to known contacts in your database, and push that information wherever you need it—your CRM, autoresponder, sales team, or ad platform.
And here’s the real magic: when one of your existing leads returns to your site—someone you’ve already collected in a compliant way—you can instantly re-engage them, just by placing a single pixel.
Let’s break this down.
What Is Identity Resolution?
Identity resolution is the process of identifying anonymous website visitors and matching them to real people using verified data sources. With SendLeads, we provide you with a pixel (a small snippet of code) to place on your website. That pixel quietly works in the background, collecting privacy-compliant behavioral and technical data to help us match visitors to actual identities—like names, emails, phone numbers, and more.
The result? You now have access to actionable data about people who visit your site—even if they didn’t fill out a form or log in.
Why Duplicates Matter (And Why You Want Them)
Most marketers focus on generating new leads, but what about the old ones—the people you already paid to acquire?
One of the most powerful use cases of the SendLeads pixel is duplicate detection. That’s right—finding people you already know.
At first, this might sound counterintuitive. Why would you want duplicate leads?
Because it allows you to re-engage them.
Imagine this: someone fills out a form on your site two months ago. They were interested—but didn’t convert. Now they’re back, browsing around. They didn’t fill out a form this time. They didn’t log in. But the pixel recognizes them.
Boom: SendLeads matches them, detects that they’re a duplicate of someone in your system, and pushes the data to wherever you want.
From there, you can:
- Send a follow-up email or SMS
- Trigger a retargeting campaign
- Add them to a sales sequence
- Flag them for your sales team to call
- Or simply know they’re back and interested again
It’s like giving your marketing system a second chance to close the deal.
How It Works (Step-by-Step)
Here’s a simple overview of how re-engagement with the SendLeads pixel works:
1. Place the Pixel on Your Website(s)
You install a lightweight snippet of code—our identity resolution pixel—on any or all of your websites. It can be added through your CMS, tag manager, or directly into the site code.
2. Visitor Arrives – Pixel Fires
As visitors land on your site, the pixel quietly collects information like IP address, device data, and behavioral signals. These signals are used to match the visitor to a real person using SendLeads’ identity graph.
3. SendLeads Matches the Visitor to a Known Contact
If the visitor is someone you already know (i.e., a duplicate), the pixel flags them. This match is based on identifiers we previously resolved—like an email or phone number—within your own lead database.
4. Matched Lead Data Is Sent Back to You
The data (either new leads or matched duplicates) is sent in real time to whatever system you choose—your CRM, Google Sheets, custom database, or marketing automation platform.
5. You Re-Engage Automatically
Once the data hits your system, you can re-engage the lead through emails, calls, ads, or any automated sequences you already have in place.
Why This Matters to Marketers and Lead Generators
Every marketer knows the pain of leads going cold. You spend time and money generating interest, but not every lead converts right away. Many just vanish into the ether.
But here’s the thing: they’re still out there. And some of them are coming back.
If you’re not tracking anonymous return visitors, you’re missing out on one of the most profitable segments of your audience—people who already know you, trust you, and are showing renewed interest.
This is exactly where the value of identity resolution comes in.
And here’s what makes it even better:
- You don’t need them to log in
- You don’t need them to re-submit a form
- You don’t need to run retargeting ads blindly
Instead, you get a direct match. A name. An email. A phone number. In real time.
And then you can act on it.
Real-World Use Case: How One Client Is Winning With Duplicates
One of our current clients has placed the SendLeads pixel across all of their owned web properties. They already generate a large number of leads through their forms and funnels. But what they’re most excited about is when SendLeads identifies a duplicate—a lead they already collected in the past.
Why?
Because they know their data is compliant and verified. When SendLeads flags a returning visitor as a duplicate, it gives them permission to re-engage that lead without waiting for another form submission.
They treat this like a second chance at revenue.
It allows them to:
- Re-open the lead in their sales CRM
- Add the lead to new email nurturing flows
- Offer limited-time promos to re-capture attention
- Even resell or remarket the lead if appropriate
In their words, “Every duplicate is an opportunity to make money again.”
The Bottom Line: Re-Engagement Is a Goldmine
Too often, companies treat website traffic like it’s disposable. People come, people go—and unless they convert right away, they’re forgotten.
But in reality, your returning traffic is often your warmest audience. They’ve been there before. They’re interested. They just need a little nudge.
SendLeads makes it possible to identify them, re-engage them, and convert them—without relying on cookies, logins, or manual list matching.
So if you’re sitting on a list of leads that’s gone quiet, or you want to unlock more revenue from the traffic you’re already getting, the answer is simple:
Install the pixel. Watch the leads come back. And re-engage them when they do.
