[[actions-email]]
=== Email action
Use the `email` action to send email notifications. To send email, you must
<<configuring-email, configure at least one email account>> in
`elasticsearch.yml`.
Email notifications can be plain text or styled using HTML. You can include
information from the watch execution payload using <<templates, templates>>
and attach the entire watch payload to the message.
See <<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]]
==== 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:
[source,js]
--------------------------------------------------
"actions" : {
"send_email" : { <1>
"email" : { <2>
"to" : "username@example.org", <3>
"subject" : "Watcher Notification", <4>
"body" : "{{ctx.payload.hits.total}} error logs found" <5>
}
}
}
--------------------------------------------------
// NOTCONSOLE
<1> The id of the action.
<2> The action type is set to `email`.
<3> One or more addresses to send the email to. Must be specified in the
action definition or in the email account configuration.
<4> The subject of the email can contain static text and Mustache <<templates,
templates>>.
<5> The body of the email can contain static text and Mustache <<templates,
templates>>. Must be specified in the action definition or in the email
account configuration.
[[configuring-email-attachments]]
==== 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.
[source,js]

.`http` attachment type attributes
[options="header"]
|=====
| Name | Description
| `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>> for
the full list of HTTP request attributes. Required.
|=====
.`data` attachment type attributes
[options="header"]
|======
| Name | Description
| `format` | Attaches the watch data, equivalent to specifying `attach_data`
in the watch configuration. Possible values are `json` or `yaml`.
Defaults to `json` if not specified.
|======
.`reporting` attachment type attributes
[options="header"]
|======
| Name | Description
| `url` | The URL to trigger the dashboard creation

created PDF. This configures the number of retries. Defaults to `40`.
The setting `xpack.notification.reporting.retries` can be configured
globally to change the default.
| `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.
| `request.auth` | Additional auth configuration for the request
| `request.proxy` | Additional proxy configuration for the request

[[email-address]]
Email Address::
An email address can contain two possible parts--the address itself and an
optional personal name as described in http://www.ietf.org/rfc/rfc822.txt[RFC 822].
The address can be represented either as a string of the form `user@host.domain`
or `Personal Name <user@host.domain>`. You can also specify an email address as
an object that contains `name` and `address` fields.

Address List::
A list of addresses can be specified as a an
array: `[ 'Personal Name <user1@host.domain>', 'user2@host.domain' ]`.
[[configuring-email]]
==== 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 <<email-html-sanitization, Configuring HTML Sanitization Options>>.
You configure the accounts {watcher} can use to send email in the
`xpack.notification.email` namespace in `elasticsearch.yml`.
The password for the specified SMTP user is stored securely in the
<<secure-settings, {es} keystore>>.
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-profile]]
{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:
* <<gmail>>
* <<outlook>>
* <<exchange>>
* <<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
<<actions-email,`email`>> action.

[[email-html-sanitization]]
===== Configuring HTML sanitization options
The `email` action supports sending messages with an HTML body. However, for
security reasons, {watcher} https://en.wikipedia.org/wiki/HTML_sanitization[sanitizes]
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`. You can specify individual HTML elements and
{ref}/notification-settings.html#html-feature-groups[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.
[source,yaml]
--------------------------------------------------
xpack.notification.email.html.sanitization:
allow: _tables, _blocks
disallow: h4, h5, h6
--------------------------------------------------
To disable sanitization entirely, add the following setting to
`elasticsearch.yml`:
[source,yaml]
--------------------------------------------------
xpack.notification.email.html.sanitization.enabled: false
--------------------------------------------------
