    'personalizations': [{'to': [{'email': u'[email protected]'}]}, {'bcc': [{'email': '[email protected]'}]}],
    'from': {'email': '[email protected]'},
    'subject': u'[LocalCache] Welcome to LocalCache',
    'content' : [{'type': 'text/plain', 'value': u'Hi Mission Liao,\n\nWelcome to LocalCache! Please take a second to confirm [email protected] as your email address by clicking this link:\n\nhttp://localhost:8080/other-api/confirm-email?code=SSZZCIQW8NGBMW6Z&email=missionaryliao%40gmail.com\n\nHigh fives,\n\nLocalCache t eam\nhttps://www.localcache.co'}]

I finally make it passed: the reply_to and bcc has duplicated email. Once remove the "bcc" part it worked.

The error is throw by urllib2.open, in the form of HTTPError, there are only "code" and "reaon" property in that exception class, in my case, they are (400, "Bad Request"), which is not very helpful.

Is there any way for python user to receive more error information?

Hi @mission-liao,

Have you tried this? https://github.com/sendgrid/sendgrid-python/blob/master/TROUBLESHOOTING.md#error

[mission-liao]

thanks for pointing out this document, after I tried e.read(), got this:

{
    "errors": [
        {
            "message":"The to array is required for all personalization objects, and must have at least one email object with a valid email address.",
            "field":"personalizations.1.to",
            "help":"http://sendgrid.com/docs/API_Reference/Web_API_v3/Mail/errors.html#message.personalizations.to"
        }
    ]
}

Although I don't why it reports "to" personalization object when the request contains one, but it's much better than nothing, thanks.

and my mail.get() is:

{'subject': 'Testing_Sendgrid', 'from': {'email': ''[email protected]'', 'name': 'qwerty'}, 'personalizations': [{'to': [{'email': ''[email protected]''}]}, {'bcc': [{'email': ''[email protected]''}], 'cc': [{'email': '[email protected]'}]}], 'content': [{'value': 'Hey this is sagar from digicollect', 'type': 'text/html'}]}

HTTP Error 400: Bad Request

@thinkingserious Is it mandatory to add To for sending email to BCC list? because i am getting
this BadRequestError while sending without To in code. thanks
