# Customize email notifications

Adapt the form and content of emails sent out from the Form Builder.

Editions: Experience

Email is one of the **Submit** button options you can add to a form in the Form Builder. Use it to configure a list of email addresses that get notifications about newly filled forms.

## Override email template

To customize the form submission email, override the `form_builder/form_submit_notification_email.html.twig` template. It contains two blocks: `subject` and `body`. Each of them is rendered independently and consists of three sets of parameters.

| Parameter | Type                                                         | Description                        |
| --------- | ------------------------------------------------------------ | ---------------------------------- |
| `content` | `Ibexa\Contracts\Core\Repository\Values\Content\Content`     | Name of the form, its content type |
| `form`    | `Ibexa\Contracts\FormBuilder\FieldType\Model\Form`           | Definition of the form             |
| `data`    | `Ibexa\Contracts\FormBuilder\FieldType\Model\FormSubmission` | Sent data                          |

## Configure sender details

Some email providers require a sender address to be set, so to avoid unsent emails when using Form Builder, it's recommended to configure `sender_address` in `config/packages/swiftmailer.yaml`. This email acts as a sender and return address for all bounced messages.

> **Note: Note**
>
> Since November 2021 the Swift Mailer is no longer supported and the integration with Symfony is deprecated in Symfony 6.0. The Swift Mailer got replaced by the Symfony Mailer.

Add `sender_address` entry to `config/packages/swiftmailer.yaml`:

```yaml
swiftmailer:
    url: '%env(MAILER_URL)%'
    spool: { type: 'memory' }
    sender_address: '%env(MAILER_SENDER_ADDRESS)%'
```

In the `.env` file, define a new environment variable: `MAILER_SENDER_ADDRESS=mail@example.com` and configure your mail server connection details in the `MAILER_URL` environmental variable.
