Message Format #

The SMTP filter retrieves email information to be sent from the context, such as the recipient, which email template to use, and the variable parameters for the email template. The message format is fixed, and the result is as follows:

{
  "template": "trial_license",
  "email":["medcl@example.com"],
  "variables": {
    "name": "Medcl",
    "company": "INFINI Labs",
    "phone": "400-139-9200"
  }
}

The field template represents the template to be used from the configuration. email represents the recipient information of the email. variables defines the variable information to be used in the template.
