* <a href="https://github.com/JoshData/python-email-validator" target="_blank"><code>email-validator</code></a> - для валідації електронної пошти.
* <a href="https://docs.pydantic.dev/latest/usage/pydantic_settings/" target="_blank"><code>pydantic-settings</code></a> - для управління налаштуваннями.

Para usar `EmailStr`, primero instala <a href="https://github.com/JoshData/python-email-validator" class="external-link" target="_blank">`email-validator`</a>.

Asegúrate de crear un [entorno virtual](../virtual-environments.md){.internal-link target=_blank}, activarlo, y luego instalarlo, por ejemplo:

```console
$ pip install email-validator
```

o con:

```console
$ pip install "pydantic[email]"
```
