# Segments

Segments are dynamic groups of contacts that automatically update based on criteria you define. Unlike static lists, segments continuously evaluate your contacts and adjust membership as contact properties change.

**P.S.** There is no limit to how many Segments each Mailtrap account can have.

**Understanding Segments vs. Lists**

* **Segments**: Automatically update based on rules and conditions
* **Lists**: Manually managed, static groups

Example: A segment for "Active Users" automatically adds contacts who opened emails in the last 30 days and removes those who haven't.
{% endhint %}

## Why use Segments?

{% tabs %}
{% tab title="Automation" %}
**Self-maintaining groups**

* No manual updates needed
* Always current membership
* Reduces human error
* Saves time on list management
  {% endtab %}

{% tab title="Precision Targeting" %}
**Complex criteria combinations**

* Multiple conditions (AND/OR)
* Behavioral targeting
* Demographic filtering
* Engagement-based grouping
  {% endtab %}

{% tab title="Real-time Updates" %}
**Always accurate**

* Instant membership changes
* Reflects latest data
* No stale information
* Perfect for time-sensitive campaigns
  {% endtab %}

{% tab title="Scalability" %}
**Grows with your database**

* Handles any contact volume
* Consistent rules application
* No performance degradation
* Efficient processing
  {% endtab %}
  {% endtabs %}
