You can configure QueryTree to send emails through your Gmail account. You'll need to update the appsettings.json with your Gmail credentials.
Example:
"Email": {
"SmtpHost": "smtp.gmail.com",
"SmtpPort": 465,
"SmtpUser": "youremail@gmail.com",
"SmtpPassword": "yourgmailpassword",
"SenderAddress": "Sender Name <youremail@gmail.com>",
"UseSSL": true,
"UseAuthentication": true
}
You may need to create an App Password for QueryTree if you're using 2 Factor Authentication.
