# Settings

This will be the reference of available settings.

## Declaring email types

As there is no auto-discovery of email types, you need to declare them yourself
using the `WAILER_EMAIL_TYPES` setting.

By example:

```python
WAILER_EMAIL_TYPES = {
    "static": "my_app.emails.Static",
    "static-no-text": "my_app.emails.StaticNoText",
    "static-no-html": "my_app.emails.StaticNoHtml",
    "hello": "my_app.emails.Hello",
    "hello-user": "my_app.emails.HelloUser",
    "styled-html": "my_app.emails.StyledHtml",
}
```

## Declaring SMS types

Same as for the emails, but for SMS types, you can define `WAILER_SMS_TYPES`.

```python
WAILER_SMS_TYPES = {
    "hello": "my_app.sms.Hello",
    "hello-user": "my_app.sms.HelloUser",
}
```

## Setting the base URL

When generating absolute links from inside the email, several settings can be
used:

-   `WAILER_BASE_URL` — To manually set the base URL of your site
-   `WAILER_SITE_ID` — To select a site from the sites framework
-   `SITE_ID` — Not wailer-specific, that's a setting from the sites
    framework that will determine which is the default site to use
