# Multisite Network

### 1. Overview

In a WordPress Multisite environment, YaySMTP provides a **Multisite option** that allows you to control how SMTP settings are applied across all subsites.

### 2. Multisite Option Behavior

#### 🔹 When **Enabled** (Global Configuration)

* SMTP settings are configured **once at the Network Admin level**
* All subsites will:
  * Inherit and use the **same SMTP configuration**
  * Share the same sender email and mailer settings
* In each subsite:
  * The **YaySMTP settings page is hidden**
  * Only the **Email Logs** section is available

👉 This ensures centralized management and consistent email behavior across the network.

#### 🔹 When **Disabled** (Per-site Configuration)

* Each subsite works **independently**
* Every subsite can:
  * Configure its own SMTP settings
  * Use different email accounts or mailers
* In each subsite:
  * Full **YaySMTP settings** are available
  * Works the same as a **single-site installation**

👉 This provides flexibility when subsites require different configurations.

### 3. Summary

* **Enable Multisite** → One global SMTP setup for all subsites
* **Disable Multisite** → Each subsite manages its own SMTP settings
