Sending email from gmail api not received but shown in sent folder

Question

I' m using gapi to send gmail. But if I send the mail to myself, it doesn't appear in my inbox. The most strange, 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 = '[email protected]',
        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);
    });
}

` The information log in console is:

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

And I can see this mail in the 'Sent' folder in Gmail, but I didn't get it in the inbox. The original of this mail in the 'Sent' folder is as follow:

send a Gmail.

Anybody knows why? Thanks very much!

Edit: I change the 'To:' in Mime message to another mailbox(not Gmail), and receive the mail correctly. Feeling More confused.

Edit: I add a 'Cc': field, It is : [email protected](myself), [email protected], [email protected], [email protected] . All the other guys(Gmail and other mailboxs) received the mail, but I still couldn't receive the mail from myself.

The original mail I received in [email protected] is as follow:

send a Gmail.

Answer 1

So to be clear, sending mail works as it sends correctly to others. In the case of sending mail to yourself (why exactly are you doing this? is this really needed as opposed to say just using messages.insert?) then it appears in only SENT but not also INBOX label. You only get one copy of the mail, that's the same irregardless of API or using web UI. The problem is that the web UI also puts that message in INBOX as well as SENT. (As you can tell, sending to yourself is a bit of a special case due to things like dupe-detection based on the Message-Id header, etc.)
