# Mail Modules

https://docs.wisecp.com/de/mail-modules

Select the mail delivery module used by the application, so transactional messages leave the system through the provider you have configured.

## Reaching the Screen

Go to **Settings → Mail**: `{admin}/modules/mail`

## What Is on the Screen

**Initial Settings** selects one default mail module. **All Modules** lists the installed mail integrations and opens provider-specific settings.

## Fields

- **Enabled Module Selection**: The mail module used for outgoing application messages. Choosing none disables module-based delivery.

## Tasks

### Select the default mail module

1. Configure the intended provider from its card under **All Modules**.
2. Return to **Initial Settings** and select that provider as the default module.
3. Save. New outgoing mail uses the selected module when its provider configuration is valid.

### Change the delivery provider

1. Configure and test the replacement module.
2. Select it under **Default Module** and save.
3. Subsequent mail is routed through the replacement provider.

## Things to Watch

> **Configure before switching**
> 
> Selecting a module does not create its provider credentials. Complete and test the module configuration first to avoid interrupted delivery.

## Privileges

**Mail Module Settings** (`MODULES_MAIL_SETTINGS`) is required.
