Nodemailer envelope

Question

I Have strange problem with Nodemailer envelope, My need is to get duplicated email from contact form, one goes to people who fill form and second is myself.

My Code:

    const mailSend = {
        from: 'info@xxx',
        to: req.body.email, 
        subject: `New Message`,
        text: req.body.message,
        envelope: { 
               from: req.body.email, 
               to: 'info@xxx' 
               }

This way when im adding envelope mails are sending only from envelope, but original not, when im deleting envelope, then works as usual. So, to make it work, i just added bcc, but still im wondering what im doing wrong.

So, to make it work, i just added bcc, but still im wondering what im doing wrong. Correct way should be without bcc, but with envelope, but cant make that work.
