SMTP
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:
# 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 Variables
Setting the optional parameter name allows multiple notifiers to be created. The notifier will bind to the service notify.NOTIFIER_NAME.
Default E-mail 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 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.
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
To use the SMTP notification, refer to it in an automation or script like in this example:
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:
- "[email protected]"
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, [email protected].
The optional images field adds in-line image attachments to the email. This sends a text/HTML multi-part message instead of the plain text default.
The optional html field makes a custom text/HTML multi-part message, allowing total freedom for sending rich html emails. In them, if you need to attach images, you can pass both arguments (html and images), the attachments will be joined with the basename of the images, so they can be included in the html page with src="cid:image_name.ext".
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.
# 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_PASSWORD"
recipient:
- "[email protected]"
- "[email protected]"
sender_name: "SENDER_NAME"
Keep in mind that Google has some extra layers of protection that need special attention. By default, the usage by external applications is limited so you will need to visit the less secure apps page and enable it to be able to send e-mails. Be aware that Google will periodically turn it off if it is not used (no e-mail is sent).
To avoid having your e-mail notifications broken due to the less secure app’s behavior, it is recommended that you enable 2-step verification on your Google account, and use an application-specific password in your notification configuration.
