# Audiences Overview
> Target the right contacts with condition-based segmentation
Audiences let you define segments of contacts based on their behavior, attributes, and history. Instead of sending to everyone, you can target specific groups for more relevant messaging.
## What is an Audience?
An **Audience** is a saved set of filter conditions that define which contacts should receive a message. When you schedule a campaign, you select one or more audiences to target.
## Why Use Audiences?
Relevant messages get more clicks
Don't over-message uninterested contacts
Target high-value segments
Test messages on specific groups
## Audience Types
### Dynamic Audiences
Dynamic audiences are evaluated at send time. The contacts included can change based on recent activity.
**Example**: "Contacts who clicked in the last 7 days"
* On Monday: includes 5,000 contacts
* On Friday: includes 6,200 contacts (as more people click)
**Coming Soon** — Static audiences are planned but not yet available.
### Static Audiences
Static audiences are fixed at creation time. Useful for one-time campaigns to a specific group.
**Example**: "Contacts who signed up on Black Friday 2024"
* Always includes exactly 3,500 contacts
## Condition Types
Build audiences using these filter types:
| Category | Conditions | Example |
| ------------------ | ---------------------------------------------------------------------------- | ------------------------------- |
| **Time-Based** | Last sent, last clicked, signup date | "Last clicked within 7 days" |
| **Count-Based** | Send count, click count, conversion count | "Clicked more than 3 times" |
| **Custom Fields** | Any field you define (queries `custom_fields.{key}` on ListContact) | "State equals California" |
| **Revenue** | Has revenue, total revenue, avg revenue, conversion count, last revenue date | "Total revenue > \$50" |
| **Signup History** | Signup method with optional time filtering on signup date | "Signed up via API" |
| **DNC** | Do Not Call status (boolean) | "Not on DNC list" |
| **Timezone** | Contact timezone (IANA format) | "Timezone is America/New\_York" |
| **Carrier** | Mobile carrier name | "Carrier is Verizon" |
## AND/OR Logic
Combine conditions with flexible logic:
Contact must match **all** conditions:
```
Last clicked within 7 days
AND Total revenue > $10
AND State = California
```
Matches contacts who clicked recently, have purchased, AND are in California.
Contact must match **any** condition:
```
State = California
OR State = Texas
OR State = Florida
```
Matches contacts in any of those states.
Combine AND and OR for complex logic:
```
(State = California OR State = Texas)
AND Last clicked within 7 days
AND NOT opted out
```
Matches contacts in CA or TX who clicked recently.
## Multi-List Targeting
Audiences can span multiple sending lists. If a contact matches the audience conditions on **any** of the selected lists, they're included.
This is useful when:
* You have contacts on multiple lists
* You want to target based on behavior across lists
* You're running a cross-brand campaign
## Audience Size
Each audience shows an estimated size:
* **Cached Size**: Updated periodically (fast but may be slightly stale)
* **Live Count**: Calculated on demand (accurate but slower)
The cached size is shown in the audience list. Click "Refresh" to get a live count.
## Best Practices
Begin with a simple audience and add conditions as needed. It's easier to refine than to debug a complex audience that's too narrow.
Use the audience preview to see which contacts match. Check that your conditions work as expected.
Use names like "High-Value CA Clickers" instead of "Audience 1". You'll thank yourself later.
Select multiple audiences when scheduling a campaign. Contacts matching ANY audience are included.
