Sending email from gmail api not received, but shown in the sending folder

Question

I use gapi to send gmail. But if I send mail to myself, it will not appear in my inbox. The strangest thing is, it appears in the "Sent" folder. `

function sendMessage(email, callback) {
    // Web-safe base64 
    var base64EncodedEmail = btoa(email).replace(/\//g,'_').replace(/\+/g,'-');
    var request = gapi.client.gmail.users.messages.send({
        'userId': 'me',
        'message': {
            'raw': base64EncodedEmail
        }
    });
    request.execute(callback);
}

function send() {
    var var to = '[e-mail]',
        subject = 'Hello World',
        content = 'send a Gmail.'

    var email = "From: 'me'\r\n"+
        "To:  "+ to +"\r\n"+
        "Subject: "+subject+"\r\n"+
        "\r\n"+
        content;
    sendMessage(email, function () {
        console.log(arguments);
    });
}

`Information registration console:

"[↵ {↵  "id": "gapiRpc",↵  "result": {↵   "id": "1471e09d88000bf7",↵   "threadId": "1471e09d88000bf7",↵   "labelIds": [↵    "SENT"↵   ]↵  }↵ }↵]↵"

And I can see this letter in the Sent folder in Gmail, but I did not receive it in the Inbox. The original of this mail in the Sent folder looks like this:

send a Gmail.

Does anyone know why? Many thanks!

Edit: I change the message "To:" in Mime to a different mailbox (not Gmail) and correctly receive mail. Feel more embarrassed.
