# Email action
Use the `email` action to send email notifications. To send email, you must [configure at least one email account](#configuring-email) in `elasticsearch.yml`.
Email notifications can be plain text or styled using HTML. You can include information from the watch execution payload using [templates](/elastic/docs-builder/docs/2798/explore-analyze/alerts-cases/watcher/how-watcher-works#templates) and attach the entire watch payload to the message.
See [Email action attributes](#email-action-attributes) for the supported attributes. Any attributes that are missing from the email action definition are looked up in the email account configuration. The required attributes must either be set in the email action definition or the account’s `email_defaults`.

## Configuring email actions

You configure email actions in the `actions` array. Action-specific attributes are specified using the `email` keyword.
For example, the following email action uses a template to include data from the watch payload in the email body:
```js
"actions" : {
  "send_email" : { 
    "email" : { 
      "to" : "username@example.org", 
      "subject" : "Watcher Notification", 
      "body" : "{{ctx.payload.hits.total}} error logs found" 
    }
  }
}
```


## Configuring email attachments

You can attach the execution context payload or data from an any HTTP service to the email notification. There is no limit on the number of attachments you can configure.
To configure attachments, specify a name for the attached file and the type of attachment: `data`, `http` or `reporting`. The `data` attachment type attaches the execution context payload to the email message. The `http` attachment type enables you to issue an HTTP request and attach the response to the email message. When configuring the `http` attachment type, you must specify the request URL. The `reporting` attachment type is a special type to include PDF rendered dashboards from kibana. This type is consistently polling the kibana app if the dashboard rendering is done, preventing long running HTTP connections, that are potentially killed by firewalls or load balancers in-between.
```js
"actions" : {
  "email_admin" : {
    "email": {
      "to": "John Doe <john.doe@example.com>",
      "attachments" : {
        "my_image.png" : { 
          "http" : { 
            "content_type" : "image/png",
            "request" : {
              "url": "http://example.org/foo/my-image.png" 
            }
          }
        },
        "dashboard.pdf" : {
          "reporting" : {
            "url": "http://example.org:5601/api/reporting/generate/dashboard/Error-Monitoring"
          }
        },
        "data.yml" : {
          "data" : {
            "format" : "yaml" 
          }
        }
      }
    }
  }
}

|----------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `content_type` | Sets the content type for the email attachment. By default,                    the content type is extracted from the response sent by the                    HTTP service. You can explicitly specify the content type to                    ensure that the type is set correctly in the email in case                    the response does not specify the content type or it’s specified                    incorrectly. Optional. |
| `inline`       | Configures as an attachment to sent with disposition `inline`. This                    allows the use of embedded images in HTML bodies, which are displayed                    in certain email clients. Optional. Defaults to `false`.                                                                                                                                                                                               |
| `request`      | Contains the HTTP request attributes. At a minimum, you must                    specify the `url` attribute to configure the host and path to                    the service endpoint. See [Webhook action attributes](/elastic/docs-builder/docs/2798/explore-analyze/alerts-cases/watcher/actions-webhook#webhook-action-attributes) for                    the full list of HTTP request attributes. Required.                      |

| `interval` | The time to wait between two polling tries. Defaults to `15s` (this                    means, by default watcher tries to download a dashboard for 10 minutes,                    forty times fifteen seconds). The setting `xpack.notification.reporting.interval`                    can be configured globally to change the default. |
| `auth`     | Additional auth configuration for the request, see                    [use watcher](/elastic/docs-builder/docs/2798/explore-analyze/report-and-share/automating-report-generation#use-watcher) for details                                                                                                                               |

### Attaching reports to an email

You can use the `reporting` attachment type in an `email` action to automatically generate a Kibana report and distribute it via email.
See [Automating report generation](https://www.elastic.co/elastic/docs-builder/docs/2798/explore-analyze/report-and-share/automating-report-generation).

## Configuring email accounts

Watcher can send email using any SMTP email service. Email messages can contain basic HTML tags. You can control which groups of tags are allowed by [Configuring HTML Sanitization Options](#email-html-sanitization).
You configure the accounts Watcher can use to send email in the `xpack.notification.email` namespace in [`elasticsearch.yml`](https://www.elastic.co/elastic/docs-builder/docs/2798/deploy-manage/stack-settings). The password for the specified SMTP user is stored securely in the [Elasticsearch keystore](https://www.elastic.co/elastic/docs-builder/docs/2798/deploy-manage/security/secure-settings).
If your email account is configured to require two step verification, you need to generate and use a unique App Password to send email from Watcher. Authentication will fail if you use your primary password.

### Email profiles

Watcher provides three email profiles that control how MIME messages are structured: `standard` (default), `gmail`, and `outlook`. These profiles accommodate differences in how various email systems interpret the MIME standard. If you are using Gmail or Outlook, we recommend using the corresponding profile. Use the `standard` profile if you are using another email system.
For more information about configuring Watcher to work with different email systems, see:
- [Sending email from Gmail](#gmail)
- [Sending email from Outlook.com](#outlook)
- [Sending email from Microsoft Exchange](#exchange)
- [Sending email from Amazon SES (Simple Email Service)](#amazon-ses)

If you configure multiple email accounts, you must either configure a default account or specify which account the email should be sent with in the `email` action.
```yaml
xpack.notification.email:
  default_account: team1
  account:
    team1:
      ...
    team2:
      ...
```


### Sending email from Gmail

Use the following email account settings to send email from the [Gmail](https://mail.google.com) SMTP service:
```yaml
xpack.notification.email.account:
    gmail_account:
        profile: gmail
        smtp:
            auth: true
            starttls.enable: true
            host: smtp.gmail.com
            port: 587
            user: <username>
```

To store the account SMTP password, use the keystore command (see [secure settings](https://www.elastic.co/elastic/docs-builder/docs/2798/deploy-manage/security/secure-settings))
```yaml
bin/elasticsearch-keystore add xpack.notification.email.account.gmail_account.smtp.secure_password
```

If you get an authentication error that indicates that you need to continue the sign-in process from a web browser when Watcher attempts to send email, you need to configure Gmail to [Allow Less Secure Apps to access your account](https://support.google.com/accounts/answer/6010255?hl=en).
If two-step verification is enabled for your account, you must generate and use a unique App Password to send email from Watcher. See [Sign in using App Passwords](https://support.google.com/accounts/answer/185833?hl=en) for more information.

#### Sending email from Outlook.com

Use the following email account settings to send email action from the [Outlook.com](https://www.outlook.com/) SMTP service:
```yaml
xpack.notification.email.account:
    outlook_account:
        profile: outlook
        smtp:
            auth: true
            starttls.enable: true
            host: smtp-mail.outlook.com
            port: 587
            user: <email.address>
```

To store the account SMTP password, use the keystore command (see [secure settings](https://www.elastic.co/elastic/docs-builder/docs/2798/deploy-manage/security/secure-settings))
```yaml
bin/elasticsearch-keystore add xpack.notification.email.account.outlook_account.smtp.secure_password
```

When sending emails, you have to provide a from address, either a default one in your account configuration or as part of the email action in the watch.
<note>
  You need to use a unique App Password if two-step verification is enabled. See [App passwords and two-step verification](http://windows.microsoft.com/en-us/windows/app-passwords-two-step-verification) for more information.
</note>


#### Sending email from Amazon SES (Simple Email Service)

Use the following email account settings to send email from the [Amazon Simple Email Service](http://aws.amazon.com/ses) (SES) SMTP service:
```yaml
xpack.notification.email.account:
    ses_account:
        email_defaults:
            from: <email address of service account> 
        smtp:
            auth: true
            starttls.enable: true
            starttls.required: true
            host: email-smtp.us-east-1.amazonaws.com 
            port: 587
            user: <username>
```

To store the account SMTP password, use the keystore command (see [secure settings](https://www.elastic.co/elastic/docs-builder/docs/2798/deploy-manage/security/secure-settings))
```yaml
bin/elasticsearch-keystore add xpack.notification.email.account.ses_account.smtp.secure_password
```

<note>
  You need to use your Amazon SES SMTP credentials to send email through Amazon SES. For more information, see [Obtaining Your Amazon SES SMTP Credentials](http://docs.aws.amazon.com/ses/latest/DeveloperGuide/smtp-credentials.md). You might also need to verify [your email address](https://docs.aws.amazon.com/ses/latest/DeveloperGuide/verify-email-addresses.md) or [your whole domain](https://docs.aws.amazon.com/ses/latest/DeveloperGuide/verify-domains.md) at AWS.
</note>


#### Sending email from Microsoft Exchange

Use the following email account settings to send email action from Microsoft Exchange:
```yaml
xpack.notification.email.account:
    exchange_account:
        profile: outlook
        email_defaults:
            from: <email address of service account> 
        smtp:
            auth: true
            starttls.enable: true
            host: <your exchange server>
            port: 587
            user: <email address of service account> 
```

To store the account SMTP password, use the keystore command (see [secure settings](https://www.elastic.co/elastic/docs-builder/docs/2798/deploy-manage/security/secure-settings))
```yaml
bin/elasticsearch-keystore add xpack.notification.email.account.exchange_account.smtp.secure_password
```


#### Configuring HTML sanitization options

The `email` action supports sending messages with an HTML body. However, for security reasons, Watcher [sanitizes](https://en.wikipedia.org/wiki/HTML_sanitization) the HTML.
You can control which HTML features are allowed or disallowed by configuring the `xpack.notification.email.html.sanitization.allow` and `xpack.notification.email.html.sanitization.disallow` settings in [`elasticsearch.yml`](https://www.elastic.co/elastic/docs-builder/docs/2798/deploy-manage/stack-settings). You can specify individual HTML elements and [HTML feature groups](https://docs-v3-preview.elastic.dev/elastic/docs-builder/docs/2798/reference/elasticsearch/configuration-reference/watcher-settings#html-feature-groups). By default, Watcher allows the following features: `body`, `head`, `_tables`, `_links`, `_blocks`, `_formatting` and `img:embedded`.
For example, the following settings allow the HTML to contain tables and block elements, but disallow  `<h4>`, `<h5>` and `<h6>` tags.
```yaml
xpack.notification.email.html.sanitization:
    allow: _tables, _blocks
    disallow: h4, h5, h6
```

To disable sanitization entirely, add the following setting to `elasticsearch.yml`:
```yaml
xpack.notification.email.html.sanitization.enabled: false
```
