Brevo + Google Analytics 4 Integration: How to Track and Optimize Your Campaigns

In today’s data-driven world, running marketing campaigns without analytics is like sailing without a compass. That’s why the Brevo + Google Analytics 4 (GA4) integration is one of the most powerful setups for marketers who want to measure, optimize, and scale campaigns intelligently.

Published by RenoEasy Marketing Edge

Introduction

GA4 provides deep behavioral tracking, and Brevo adds the automation layer — together, they create a full circle of marketing visibility.

At RenoEasy Marketing Edge, we’ve analyzed how this integration transforms your Brevo campaigns — helping you understand which emails, automations, and audiences generate the most engagement, conversions, and revenue.

1. What is the Brevo + Google Analytics 4 Integration?

This integration connects Brevo’s marketing and automation data with Google Analytics 4’s event tracking system.

In simple terms, GA4 tracks how users interact with your website, and Brevo shows you how they got there — through an email, SMS, or campaign.

When you link both platforms:

  • Every Brevo campaign click is tracked in GA4.
  • You can see traffic sources labeled as “Brevo / Email” or “Brevo / Automation.”
  • GA4 shows you how those users behaved after clicking your campaign — pages visited, time spent, conversions, and even revenue.

“Brevo creates engagement. GA4 shows the story behind that engagement.”

2. Why This Integration Matters

The shift from Universal Analytics to GA4 has changed how marketers track data. GA4 is built around events, not sessions, making it more flexible for modern omnichannel marketing.

Here’s why connecting Brevo with GA4 is a must:

  • Get real-time insights into how Brevo campaigns drive traffic.
  • Understand conversion paths from email → site → sale.
  • Track which automation workflows perform best.
  • Measure cross-device engagement.
  • Build data-backed marketing strategies that actually convert.

If your Brevo email campaign promotes a product, GA4 tells you which link was clicked, how long users stayed, and how many completed checkout.

4. Setting Up Brevo + GA4 (Step-by-Step)

Step 1: Prepare Your GA4 Account

Sign in to your Google Analytics account. Ensure your property has GA4 enabled. Go to Admin → Data Streams → Web, then note your Measurement ID (G-XXXXXXX).

Step 2: Enable UTM Tracking in Brevo

In your Brevo Dashboard, navigate to: Campaigns → Settings → Advanced Settings. Enable Google Analytics Tracking. Brevo automatically adds UTM parameters like: utm_source=brevo&utm_medium=email&utm_campaign=campaign_name. Save your settings.

You can customize your UTMs manually if you prefer unique identifiers for each campaign or workflow.

Step 3: Verify Tracking in GA4

Open GA4 → Reports → Traffic Acquisition. Look for “Brevo / Email” or “Brevo / Automation” as traffic sources. Check clicks, engagement rate, conversions, and revenue metrics.

Step 4: Add GA4 Tracking Code to Website

If your website doesn’t have GA4 already: Add the GA4 Global Site Tag to your website <head> section. If using WordPress, install a plugin like Site Kit by Google or GA Google Analytics. Verify data flow in the Realtime Report.

Step 5: Combine Automation Data

Inside Brevo: Go to Reports → Campaign Performance → Click Map. Compare with GA4’s Engagement → Pages & Screens Report. Identify high-performing links and workflows.

Use Brevo’s Automation + GA4 Goals together to understand which automations actually generate conversions.

5. How Data Flows Between Brevo and GA4

When a user clicks a Brevo email or SMS, the link includes UTM tags (added by Brevo). GA4 captures these UTMs as source/medium data. Events like page_view, scroll, or purchase are tracked. Brevo’s automation can react to that — for example, send a follow-up email after a user visits a pricing page.

A lead clicks a Brevo newsletter → visits product page → doesn’t buy. GA4 records the session, and Brevo’s automation sends a discount email 3 hours later. That’s behavior-based automation with full visibility.

6. Advanced Tracking: Using Events & Conversions

To track conversions, define GA4 events linked to Brevo campaigns: purchase, sign_up, add_to_cart, view_promo. Then mark important events as Conversions in GA4 → Configure → Conversions. Now you’ll know exactly which Brevo email or automation triggered a sale or lead conversion.

“With Brevo and GA4 combined, marketers finally see the full path — from click to conversion.”
