Solution – Why nodemailer is not sending email

-> If your google account is enabled with 2-factor authentication, then you can’t use your regular password as authentication while creating transport auth to access & send email programmatically.

var transporter = nodemailer.createTransport({
    service:'gmail',
    auth:{
        user:'rajatrrpalankar@gmail.com',
        pass:'your regular password'   // instead you should use app specific password here
    }
}); // initialize create Transport service

To send email using nodejs nodemailer you need to generate app-specific login credential(password) & use it as auth password.

How to generate app-specific password for gmail access

To send email from your nodejs script using nodemailer you need to generate app-specific password, using which you can get accessed to your gmail account to send email from nodejs app.

How to generate app password in google account

var transporter = nodemailer.createTransport({
    service:'gmail',
    auth:{
        user:'rajatrrpalankar@gmail.com',
        pass:'paste google app password here'
    }
}); // initialize create Transport service
