SMTP
The SMTP platform allows you to deliver notifications from Home Assistant to an email recipient.
To enable notification by email in your installation, add the following to your configuration.yamlThe configuration.yaml file is the main configuration file for Home Assistant. It lists the integrations to be loaded and their specific configurations. In some cases, the configuration needs to be edited manually directly in the configuration.yaml file. Most integrations can be configured in the UI. [Learn more] file:
# Example configuration.yaml entry
notify:
- name: "NOTIFIER_NAME"
platform: smtp
sender: "YOUR_SENDER"
recipient: "YOUR_RECIPIENT"
Check your email provider configuration or help pages to get the correct SMTP settings. A restart of Home Assistant is required to pick up the configuration changes.
Configuration Variables
Setting the optional parameter name allows multiple notifiers to be created. The notifier will bind to the notify.NOTIFIER_NAME action.
Default email address of the recipient of the notification. This can be a recipient address or a list of addresses for multiple recipients.
This is where you want to send your email notifications by default (when not specifying target in the action). Any email address(es) specified in the action’s target field will override this recipient content.
Password for the SMTP server that belongs to the given username. Make sure to wrap it in double quotes; e.g., "MY_PASSWORD".
Sets a custom ‘sender name’ in the emails headers (From: Custom name [email protected]).
Usage
A notify integration will be created using the name without spaces. In the above example, it will be called notify.NOTIFIER_NAME. To use the SMTP notification, refer to it in an automation or script like in this example:
- alias: "Send E-Mail Every Morning"
triggers:
- platform: time
at: "08:00:00"
actions:
- action: notify.NOTIFIER_NAME
data:
title: "Good Morning"
message: "Rise and shine"
target:
- "[email protected]"
The optional target field is used to specify recipient(s) for this specific action. When target field is not used, this message will be sent to default recipient(s), specified in the recipient part of the smtp notifier in configuration.yaml. Line breaks can be added in the body part of the email by using \r\n, for instance message: "Rise and shine\r\n\r\nIt's a brand new day!"
Another example attaching images stored locally in a script:
burglar:
alias: "Burglar Alarm"
sequence:
- action: shell_command.snapshot
- delay:
seconds: 1
- action: notify.NOTIFIER_NAME
data:
title: "Intruder alert"
message: "Intruder alert at apartment!!"
target:
- "[email protected]"
data:
images:
- /home/pi/snapshot1.jpg
- /home/pi/snapshot2.jpg
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.
When adding images, make sure the folders containing the attachments are added to allowlist_external_dirs.

Specific email provider configuration
Check below some configurations examples for specific email providers. If you are in doubt about the SMTP settings required, check your email provider configuration or help pages for more information about its specific SMTP configuration.
Google Mail
A sample configuration entry for Google Mail.
# Example configuration.yaml entry for Google Mail.
notify:
- name: "NOTIFIER_NAME"
platform: smtp
server: "smtp.gmail.com"
port: 587
timeout: 15
sender: "[email protected]"
encryption: starttls
username: "[email protected]"
password: "YOUR_APP_PASSWORD"
recipient:
- "[email protected]"
- "[email protected]"
sender_name: "SENDER_NAME"
Google has some extra layers of protection that need special attention. You must use an application-specific password
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
. - 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.
