Correct YAML configuration for SMTP

Configuration
1

I am setting up an automation to run every day at a specified time to send and email containing the current temperature of a DS18B20 sensor connected to a ESP8266. I have found the basic configuration.yaml file in previous posts, but I get the following error.

Message malformed: extra keys not allowed @ data['notify']

Here is the full configuration.yaml file for the automation

notify:
- name: daily_sms
  platform: smtp
  server: smtp.gmail.com
  port: 587
  timeout: 15
  sender: [MY_USERNAME]@gmail.com
  encryption: starttls
  username: [MY_USERNAME]@gmail.com
  password: [MY_PASSWORD]
  recipient: [RECIPIENT]@gmail.com

automation:
  alias: Chest Freezer Daily Text
  description: Send daily text with current temperature of chest freezer
  mode: single

  trigger:
    - platform: time
      at: '21:50:00'

  condition: []

  action:
      data:
        message: The temperature in the chest freezer is {{states("sensor.chest_freezer_temperature")}}C
        title: Daily Freezer Status
      service: notify.daily_sms

I have not been able to find any clear solutions on how to set this up.

Thanks!

Try quotes around message and title strings

The same error comes up with quotes. I think the error is from the initial notify section, but I am just not sure what it wants.
