# People
People is the user database in Netmera. Use it to find users, build target lists, tag users, and export results.
**Path:** `Targeting > People`
### Search modes
You can search in three ways:
1. **Select People**: quick filtering with predefined fields.
2. **Advanced**: build rules with condition groups.
3. **Find Person**: open a single user by identifier.
### Option 1: Select People
Select People is the fastest way to build a list. You combine filters and review the resulting users.
#### Filter categories
**Permissions**
Use these filters to include or exclude users based on opt-in status.
* **Push Permission**: targets users who allowed or blocked push notifications.
* **Category Permission**: targets users by category-level permissions (when your app uses notification categories).
* **Location Preferences**: targets users by location permission status (allowed / denied).
**User grouping**
Use these filters to target existing user groups.
* **Tag**: targets users you labeled earlier. Tags are manual or operational groupings.
* **Segment**: targets users in a segment. Segment membership can change dynamically based on rules and behavior.
**Profile**
Use this to target users by profile attributes.
* **Profile**: filters by attributes like age, gender, membership level, city, or any custom profile attribute.
**Engagement**
Use these filters to target users based on interaction and incentive state.
* **Response**: filters users by whether they interacted with previous messages (or did not).
* **Promotion**: filters users by whether they have a promotion code/value (or not).
* **Blacklist**: include or exclude users based on blacklist status (for example, to avoid messaging blocked users).
**Device / technical**
Use these filters when you need technical scoping (platform, version, provider, etc.).
* **Platform**: iOS vs Android.
* **Device Count**: targets users by how many devices are linked to their profile (useful for multi-device vs single-device users).
* **Device Type**: phone vs tablet (and other device categories if available).
* **Device**: device model/manufacturer based targeting.
* **Operator**: telecom operator based targeting.
* **App Version**: target or exclude specific app versions.
* **Operating System**: OS version level targeting (for example iOS 17+).
* **Android Provider**: provider-level targeting (for example Google vs Huawei).
* **Installation Source**: acquisition source via Adjust (requires Adjust integration).
* **App Tracking**: Android-only targeting based on installed apps (App Tracking feature).
* **App Installation**: targets users by install status or install timing windows.
### Option 2: Advanced search
Advanced search lets you build complex rules. You combine conditions and groups with AND/OR logic.
{% hint style="info" %}
**AND vs OR**
* **OR**: at least one condition in the group must match.
* **AND**: all conditions in the group must match.
{% endhint %}
#### Add Condition
Use **Add Condition** to add a single rule.
#### Add Group
Use **Add Group** to nest conditions and build more complex logic.
### Actions on the results (Tagging & Export)
After you build a user list, you typically do one of these actions:
#### Start Tagging
Use **Start Tagging** to create a tag from the result list. You can later message, export, or manage that tag from the Tags dashboard.
{% hint style="info" %}
See [Tags](https://user.netmera.com/netmera-user-guide/targeting/tags) for tag management and messaging flows.
{% endhint %}
#### Export Selected Users to File
Use Export to download the current list for analysis or external processing.
You can export multiple user identifiers in the same file. This export uses the same behavior described in [Export Module](https://user.netmera.com/netmera-user-guide/targeting/export-users).
Key points:
* Identifier selection supports **multi-select** (e.g., External ID + Email + MSISDN).
* Each selected identifier becomes a **separate column**.
* Missing values are exported as `null`.
* Format is `.csv` or `.xlsx` (depending on the screen).
### Option 3: Find Person
Use Find Person to open a single user quickly. Search by external ID or email.
### User Details
Click a user’s External ID to open User Details. You can review profile, devices, activity, and messaging history.
Available tabs include:
* Profile
* Devices
* Events
* Messages
* Targeting
* Device Opt-In
* User Opt-In
* Blacklist
* Privacy
* Coupon Codes
#### Messages tab
The Messages tab shows the user’s message history for a selected date range. It is useful for support, audits, and troubleshooting.
For failed deliveries, you can see details like:
* **Failure reason** (error message)
* **Error code** (if provided by the SMS provider)
Date range rules:
* Query in **30-day** intervals.
* Access up to the **last 6 months (180 days)**.
