How to send 100% of your website events to Twilio Segment

Twilio Segment is one of the most popular Customer Data Platforms (CDPs) in the world. If you're building a modern data stack, chances are you're already using Segment to capture user behavior and route that data to destinations like warehouses, analytics tools, marketing automation platforms, and more.

But here's a surprising truth: even if Segment is set up correctly on your website, you might still be missing a huge portion of your data.

In this hands-on tutorial, we'll explore why most Segment implementations silently drop events and how you can use Edgee to capture 100% of web interactions reliably, securely, and compliantly.

Why you're not capturing all events in Segment

Even the best Segment setups suffer from invisible blind spots due to three major factors:

#1 Consent regulations

Privacy regulations like GDPR and CCPA require websites to ask for explicit user consent before collecting personal data. This is good news for user privacy, but a real headache for data quality.

According to recent benchmarks, only 31% of users fully consent to cookies and tracking scripts. That means ~70% of your users never trigger the Segment SDK at all.

#2 Ad blockers

Segment's client-side library (analytics.js) is often blocked by browser extensions like uBlock Origin, Ghostery, and Brave's native shields. Since these tools target known analytics domains and scripts, Segment requests are blocked before they ever leave the browser.

In Europe and North America, over 30% of internet users use some form of ad blocker, with higher percentages if your target audience is highly educated or technical. That's a major hit to your data reliability.

#3 Mobile + network variability

As mobile usage surpasses desktop, issues like poor connectivity and script loading errors become more frequent. Segment's JavaScript SDK depends on a functioning browser, network, and user session, all of which can fail silently on flaky networks or older browsers.

What if you could send events to Segment before the page loads?

Instead of relying on fragile JavaScript SDKs, imagine if you could:

• Respect user consent and privacy.
• Avoid ad blocker interference.
• Reduce JavaScript dependencies.
• Still send complete events to Segment.

With Edgee, that's exactly what you can do, without relying on client-side SDKs or complex server-side implementations.

Edgee lets you replace JavaScript SDKs with lightweight WebAssembly components that run at the edge. This means that your analytics and data routing logic lives between the user and your server, not in the browser.

Why use Edgee for Segment?

Using the Segment component on Edgee, you can:

• Replace analytics.js with the Edgee SDK.
• Automatically send page, track, and identify events from the edge.
• Avoid ad blockers, script errors, and JavaScript compatibility issues.
• Improve compliance by centralizing consent handling.
• Reduce client-side overhead for better website performance.

Getting started with Edgee + Segment in 5 steps

🛠️ You can implement this in under 30 minutes. No credit card required, with our free tier.

1. Create a free Edgee account
2. Create a new project and define your backend domain
3. Add the Segment component to your project
4. Replace analytics.js with the Edgee SDK on your site
5. Map events using our No-Code Data Layer or via code

Replacing analytics.js

Here's how to go from this:

<script>
  !function(){
    ...
    analytics.load("SEGMENT_WRITE_KEY");
    analytics.page();
  }();
</script>

To this:

<script id="__EDGEE_SDK__" src="<YOUR_SDK_URL>" async></script>

Then update your custom events:

// from analytics.js
analytics.track('Product Viewed', {
  product: '123',
  name: 'Cool Shoes'
});

// to Edgee
edgee.track({
  name: 'Product Viewed',
  properties: {
    product: '123',
    name: 'Cool Shoes'
  }
});

And for user identification:

// from analytics.js
analytics.identify('f4ca124298', {
  name: 'Michael Brown',
  email: 'mbrown@example.com'
});

// to Edgee
edgee.user({
  user_id: 'f4ca124298',
  properties: {
    name: 'Michael Brown',
    email: 'mbrown@example.com'
  }
});

Consent-aware event collection

Edgee has built-in support for popular CMPs (Consent Management Platforms) like Axeptio, CookieYes, Didomi, Iubenda, OneTrust, and more coming soon.

This ensures that your Segment events only fire when users have given explicit permission, automatically and at the edge.

Migration strategy: gradual or full replacement

Depending on your risk tolerance and setup complexity, you can choose one of two paths:

1. Dual setup (Integrate + Compare)

Run Edgee and Segment side-by-side using a separate Segment source.

We recommend running a (free) proof of concept for at least 3-4 weeks. This allows you to compare event counts and understand the extent of data loss, making it ideal for testing Edgee's coverage before replacing your existing setup.

2. Full replacement (Integrate + Replace)

Remove analytics.js entirely, and switch all tracking to Edgee. You'll get:

• Fewer scripts to manage and better security posture.
• Faster performance resulting in improved Core Web Vitals and SEO ranking.
• More accurate and compliant data collection.

Follow the migration guide for a smooth implementation and migration process.

To sum up: client-side SDKs were great in the early days of web analytics. But with growing privacy regulations, ad blockers, and inconsistent mobile connectivity, they’re no longer reliable.

Edgee + Segment offers a future-proof alternative, shifting event collection from the browser to the edge, without compromising user privacy or data accuracy. If you're building a modern analytics stack, this is your next upgrade. ✨
