The SMTP platform allows you to deliver notifications from Home Assistant to an e-mail recipient.

To enable notification by e-mail in your installation, add the following to your `configuration.yaml` file:

```yaml
# Example configuration.yaml entry
notify:
  - name: "NOTIFIER_NAME"
    platform: smtp
    sender: "YOUR_SENDER"
    recipient: "YOUR_RECIPIENT"
```

Check your e-mail provider configuration or help pages to get the correct SMTP settings.

{% configuration %}
name:
  description: Setting the optional parameter `name` allows multiple notifiers to be created. The notifier will bind to the service `notify.NOTIFIER_NAME`.
  required: false
  type: string
  default: notify
sender:
  description: E-mail address of the sender.
  required: true
  type: string
recipient:
  description: Default E-mail address of the recipient of the notification. This can be a recipient address or a list of addresses for multiple recipients.<br>This is where you want to send your E-mail notifications by default (when not specifying `target` in the service call). Any E-mail address(es) specified in the service call's `target` field will override this recipient content.
  required: true
  type: [list, string]

### Usage

To use the SMTP notification, refer to it in an automation or script like in this example:

```yaml
burglar:
  alias: "Burglar Alarm"
  sequence:
    - service: shell_command.snapshot
    - delay:
          seconds: 1
    - service: notify.NOTIFIER_NAME
      data:
          title: "Intruder alert"
          message: "Intruder alert at apartment!!"
          target:
            - "my_intruder_alert@example.com"
          data:
              images:
                  - /home/pi/snapshot1.jpg
                  - /home/pi/snapshot2.jpg
```

The optional `target` field is used to specify recipient(s) for this specific service call. When `target` field is not used, this message will be sent to default recipient(s), in this example, my_intruder_alert@example.com.

The optional `html` field makes a custom text/HTML multi-part message, allowing total freedom for sending rich HTML emails by defining the HTML content. In them, if you need to include images, you can pass both arguments (`html` and `images`). The images will be attached with the basename of the images, so they can be included in the html page with `src="cid:image_name.ext"`.

The optional `images` field adds image attachments to the email. If `html` is defined, the images need to be added to the message in-line as described above (and as shown in the example below). If `html` is not defined, images will be added as separate attachments.

```yaml
burglar:
  alias: "Burglar Alarm"
  sequence:
    - service: shell_command.snapshot
    - delay:
          seconds: 1
    - service: notify.NOTIFIER_NAME
      data:
          message: "Intruder alert at apartment!!"
          data:
            images:
              - /home/pi/snapshot1.jpg
              - /home/pi/snapshot2.jpg

## Specific E-Mail Provider Configuration

Check below some configurations examples for specific e-mail providers.
If you are in doubt about the SMTP settings required, check your e-mail provider configuration or help pages for more information about its specific SMTP configuration.

### Google Mail

A sample configuration entry for Google Mail.

```yaml
# Example configuration.yaml entry for Google Mail.
notify:
  - name: "NOTIFIER_NAME"
    platform: smtp
    server: "smtp.gmail.com"
    port: 587
    timeout: 15
    sender: "YOUR_USERNAME@gmail.com"
    encryption: starttls
    username: "YOUR_USERNAME@gmail.com"
    password: "YOUR_APP_PASSWORD"
    recipient:
      - "RECIPIENT_1@example.com"
      - "RECIPIENT_N@example.com"
    sender_name: "SENDER_NAME"
```

Google has some extra layers of protection that need special attention. You must use [an application-specific password](https://support.google.com/mail/answer/185833) in your notification configuration.

If any of the following conditions are met you will not be able to create an app password:

- You do not have 2-step verification enabled on your account.
- You have 2-step verification enabled but have only added a security key as an authentication mechanism.
- Your Google account is enrolled in Google's [Advanced Protection Program](https://landing.google.com/advancedprotection/).
- Your Google account belongs to a Google Workspace that has disabled this feature. Accounts owned by a school, business, or other organization are examples of Google Workspace accounts.
