How to Segment Your Contacts Based on Behavior

Most marketers already have the data they need to run targeted campaigns — they just aren’t using it.

You’re tracking who’s opening emails, clicking on product links, or signing up for trials. But without proper segmentation, that data sits idle. You end up sending generic emails to everyone, even though your contacts are telling you exactly what they care about through their behavior.

In this guide, we’ll discuss how you can segment your contacts based on the behavior of your customers.

What kinds of behaviors matter when segmenting your contacts

Behavioral segmentation lets you group users based on how they’ve interacted with your brand. This can go far beyond simple opens or clicks.

Here are some key behavioral signals you can use:

• Link clicks — Users who clicked on specific links (e.g., “Pricing”, “Features”, “Book a demo”)

• Engagement level — Active users vs. inactive users over a period of time

• Campaign activity — Opened, clicked, submitted a form, etc.

• Signup date — New users who joined in the last X days

• Custom event triggers — Actions taken inside your app (e.g., completed onboarding)

Mailmodo allows you to create segments using all of these behavior types — giving you the control and flexibility to personalize at scale.

How to set up behavior-based segmentation in Mailmodo

You can create behavior-driven segments in Mailmodo using a simple, guided workflow — whether you're targeting based on link clicks, engagement levels, signup dates, or custom conditions.

Here’s how it works:

Step 1: Go to Contacts → Create Segment. Here, you can choose to create a segment with a builder or using Mailmodo AI

Step 2: If you’re choosing to create using Mailmodo AI, describe the segment you want to create.

Step 3: In case of Mailmodo AI, you’ll get a preview of the segment. Click on Edit using builder to make your final tweaks.

For the manual version, fill the details as shown in the image below.

Step 4: Define your conditions based on the kind of behavior you want to segment your users on.

Step 5: Click on Create segment

You can now use this segment in any campaign — automated journeys, broadcast emails, or triggered follow-ups.

Final recommendations

Behavioral segmentation doesn’t have to be complex — but it should be intentional.

By segmenting based on what users actually do — not just who they are — you’ll create more relevant campaigns, improve conversions, and get more value out of every send.
