+# Notification Text Templates
+
+> Customize how devices and events appear in **text** notifications (email previews, push notifications, Apprise messages).
+
+By default, NetAlertX formats each device as a vertical list of `Header: Value` pairs. Text templates let you define a **single-line format per device** using `{FieldName}` placeholders — ideal for mobile notification previews and high-volume alerts.
+
+HTML email tables are **not affected** by these templates.
+
+## Quick Start
+
+1. Go to **Settings → Notification Processing**.
+2. Set a template string for the section you want to customize, e.g.:
+   - **Text Template: New Devices** → `{Device name} ({MAC}) - {IP}`
+3. Save. The next notification will use your format.
+
+**Before (default):**
+```
+🆕 New devices
+---------
+MAC: 	    aa:bb:cc:dd:ee:ff
+Datetime: 	2025-01-15 10:30:00
+IP: 	    192.168.1.42
+Event Type: New Device
+Device name: MyPhone
+Comments:
+```
+
+**After (with template `{Device name} ({MAC}) - {IP}`):**
+```
+🆕 New devices
+---------
+MyPhone (aa:bb:cc:dd:ee:ff) - 192.168.1.42
+```
+
+## Settings Reference
+
+| Setting | Type | Default | Description |
+|---------|------|---------|-------------|
+| `NTFPRCS_TEXT_SECTION_HEADERS` | Boolean | `true` | Show/hide section titles (e.g. `🆕 New devices \n---------`). |
+| `NTFPRCS_TEXT_TEMPLATE_new_devices` | String | *(empty)* | Template for new device rows. |
+| `NTFPRCS_TEXT_TEMPLATE_down_devices` | String | *(empty)* | Template for down device rows. |
+| `NTFPRCS_TEXT_TEMPLATE_down_reconnected` | String | *(empty)* | Template for reconnected device rows. |
+| `NTFPRCS_TEXT_TEMPLATE_events` | String | *(empty)* | Template for event rows. |
+| `NTFPRCS_TEXT_TEMPLATE_plugins` | String | *(empty)* | Template for plugin event rows. |
+
+When a template is **empty**, the section uses the original vertical `Header: Value` format (full backward compatibility).
+
+## Template Syntax
+
+Use `{FieldName}` to insert a value from the notification data. Field names are **case-sensitive** and must match the column names exactly.
+
+```
+{Device name} ({MAC}) connected at {Datetime}
+```
+
+- No loops, conditionals, or nesting — just simple string replacement.
+- If a `{FieldName}` does not exist in the data, it is left as-is in the output (safe failure). For example, `{NonExistent}` renders literally as `{NonExistent}`.
+
+## Variable Availability by Section
+
+Each section has different available fields because they come from different database queries.
+
+### `new_devices` and `events`
+
+| Variable | Description |
+|----------|-------------|
+| `{MAC}` | Device MAC address |
+| `{Datetime}` | Event timestamp |
+| `{IP}` | Device IP address |
+| `{Event Type}` | Type of event (e.g. `New Device`, `Connected`) |
+| `{Device name}` | Device display name |
+| `{Comments}` | Device comments |
+
+**Example:** `{Device name} ({MAC}) - {IP} [{Event Type}]`
+
+### `down_devices` and `down_reconnected`
+
+| Variable | Description |
+|----------|-------------|
+| `{devName}` | Device display name |
+| `{eve_MAC}` | Device MAC address |
+| `{devVendor}` | Device vendor/manufacturer |
+| `{eve_IP}` | Device IP address |
+| `{eve_DateTime}` | Event timestamp |
+| `{eve_EventType}` | Type of event |
+
+**Example:** `{devName} ({eve_MAC}) {devVendor} - went down at {eve_DateTime}`
+
+### `plugins`
+
+| Variable | Description |
+|----------|-------------|
+| `{Plugin}` | Plugin code name |
+| `{Object_PrimaryId}` | Primary identifier of the object |
+| `{Object_SecondaryId}` | Secondary identifier |
+| `{DateTimeChanged}` | Timestamp of change |
+| `{Watched_Value1}` | First watched value |
+| `{Watched_Value2}` | Second watched value |
+| `{Watched_Value3}` | Third watched value |
+| `{Watched_Value4}` | Fourth watched value |
+| `{Status}` | Plugin event status |
+
+**Example:** `{Plugin}: {Object_PrimaryId} - {Status}`
+
+> [!NOTE]
+> Field names differ between sections because they come from different SQL queries. A template configured for `new_devices` cannot use `{devName}` — that field is only available in `down_devices` and `down_reconnected`.
+
+## Section Headers Toggle
+
+Set **Text Section Headers** (`NTFPRCS_TEXT_SECTION_HEADERS`) to `false` to remove the section title separators from text notifications. This is useful when you want compact output without the `🆕 New devices \n---------` banners.
