How to Use Tags and Segments Inside Automation Workflows

Category: Brevo Marketing Automation — Written by Email Educate

Tags and segments are two of the most powerful tools inside Brevo. They allow you to group contacts by behavior, interests, actions, and profile details — and then use those groups inside automation workflows. When used correctly, tags and segments transform your automations from simple email sequences into smart, personalized journeys that adjust to each subscriber automatically. This guide walks you through every element of using tags and segments inside workflows, using a friendly and practical step-by-step approach suited for 2026.

Key Tip — Tags represent actions. Segments represent audiences. When you combine both, your automation becomes intelligent and behavior-based.

Why Tags and Segments Matter in Email Automation

Most automation beginners think workflows only send emails on timers. But real automation adapts to how people behave — what they click, what they buy, how they browse, and how engaged they are. Tags and segments unlock this personalization. They help you:

  • Track subscriber behavior automatically
  • Send different messages to different audiences
  • Build automated journeys that respond to actions in real time
  • Improve relevance, engagement, and deliverability
  • Avoid sending irrelevant content to the wrong people

This is the foundation of modern marketing automation — and Brevo makes it surprisingly simple.

Tags vs Segments — Simple Explanation for Beginners

Tags = Quick labels

Tags are instant markers you attach to contacts during workflows. Example: “Clicked Guide,” “VIP,” “Not Interested.”

Segments = Dynamic groups

Segments automatically include or remove contacts based on conditions — like engagement, clicks, or purchase behavior.

Tags feed segments

Tag behavior → segment updates → triggers automation.

Segments improve targeting

You can send email sequences only to people who match exact criteria.

Both improve automation accuracy

They ensure people only receive emails that match their journey.

Brevo’s advantage

Tags + segments work perfectly inside Brevo’s visual builder.

How to Use Tags Inside Automation Workflows

Tags are the “signals” your workflows use to track behavior. They help you respond instantly when someone takes an action worth noting.

Common tagging examples:

  • Tag → “Clicked Welcome Email”
  • Tag → “Viewed Pricing Page”
  • Tag → “Downloaded Ebook”
  • Tag → “Interested in Automation”
  • Tag → “Cold Contact”
  • Tag → “New Customer”

Where tags fit inside workflows:

  • After a click event
  • After a condition
  • After purchase tracking
  • After completing a specific action

Tags are especially useful because they are instant — the moment an event happens, the tag is applied.

How to Use Segments Inside Workflows

Segments update automatically based on conditions you define. They are perfect for long-term organization and advanced targeting.

Popular segment ideas:

  • Engaged Subscribers (opened/clicked in last 14 days)
  • Cold Subscribers (no opens in 45 days)
  • High-Intent Users (visited pricing page)
  • New Customers (purchased once)
  • VIP Customers (multiple purchases)

Segments trigger workflows automatically

You can create an automation that starts when someone:

  • Joins a segment
  • Leaves a segment

Example workflow:

  • User clicks product link → Tag applied
  • Tag adds them into “High Intent” segment
  • Segment triggers a 3-email targeted sequence

Combining Tags and Segments for Smarter Automation

The real power arrives when you combine tags and segments together. This creates a fully adaptive automation system.

Example 1 — Behavior-Based Nurture

  • Subscriber clicks guide → Tag applied
  • Tag adds them to “Engaged” segment
  • Segment triggers nurture automation

Example 2 — Cold Audience Cleanup

  • No open for 45 days → Tag “Cold Contact”
  • Segment “Cold Subscribers” updated
  • Automation sends reactivation sequence

Example 3 — Purchase Journey

  • Purchase event → Tag “Customer”
  • Customer joins “New Customer Segment”
  • Segment triggers onboarding workflow
