BCC return 400 bad request

Bcc return 400 bad request

when i added the email in bcc method it return 400 bad request error.

Here is my snippet:

sg = sendgrid.SendGridAPIClient(apikey=SENDGRID_API_KEY)
from_email = Email(self.from_address)
to_list = Personalization()
attachments = []
for email in emails:
self.email = email
to_list.add_to(Email(email))

this code working great but when i replace the last line of snippet "to_list.add_bcc(Email(email))"
then it return 400 bad request error

hi @thinkingserious,

sorry for delayed reply..
Here's the output of print(mail.get())

{
    "content": [
        {
            "type": "text/html",
            "value": "test...."
        }
    ],
    "from": {
        "email": "admin@mailinator.net"
    },

                },
                {

Hi @gurmukhspider,

I see the issue now, thanks!

Each personalization needs to have at least one to field.

i have added "to" field but still show 400 bad request error :(

{'from': {'email': 'admin@ds.com'}, 'subject': 'HI This is testing', 'personalizations': [{'to': [{'email': 'hylomaqy@mailinator.net'}], 'bcc': [{'email': 'admin@ds.com'}, {'email': 'hylomaqy@mailinator.net'}]}], 'content': [{'type': 'text/html', 'value': 'testing'}]}

Can you please try printing out the error message? Thanks!

Hi,
I have the same error but with cc. I also received the 400 bad request error.
In my case, the problem was that is not possible send email in cc if this email is the same that destination mail (to_emails). I'm reviewing your request and you also use {'email': 'hylomaqy@mailinator.net'} in to_email and bcc_email.
I think that it could be a bug, because any mail server allow send mails to an email with the same email in copy.
Best regards,

Ah, good catch @p3r1c0,

Indeed, Twilio SendGrid does not allow duplicate emails in the Personalization object. Here is the documentation.

Thanks!

That said, I'm leaving this open so that we can return a useful error message.

With Best Regards,
