SparkPost
SparkPost.transmissions.send is ignoring CC: and BCC: if recipient list ID is provided
My test code sends out email messages as intended to the given recipient list but appears to completely ignore the CC: and BCC: addresses. (Unless there's something wrong in the below invocation?)
SDK version: 1.3.10
Code:
from sparkpost import SparkPost
sp = SparkPost("1234..........6789")
response = sp.transmissions.send(
use_sandbox=False,
recipient_list="acme-test-recipient-list",
html="<html><body><p>This is a test email notif; please ignore.</p></body></html>",
from_email="[email protected]",
subject="Test email message; please ignore",
bcc=["[email protected]", "[email protected]"],
reply_to="[email protected]",
)
print(response)
From debugging, I can tell the field is making it into the payload but doesn't appear to be used (email doesn't get sent to the CC: or BCC: addresses)
{
"bcc": ["[email protected]", "[email protected]"],
"content": {
"from": {
"email": "[email protected]"
},
"reply_to": "[email protected]",
"subject": "Test email message; please ignore",
"html": "<html><body><p>This is a test email notif; please ignore.</p></body></html>"
},
"options": {
"sandbox": false
},
"recipients": {
"list_id": "acme-test-recipient-list"
}
}
Responses look like this:
{
'total_rejected_recipients': 0,
'total_accepted_recipients': 2,
'id': '7204854351104320440'
}
(Of note: I have tried supplying CC or BCC as a string vs. list, and a single value vs. multiple values, to no avail so far)
Any idea as to why this is happening? A workaround? Thanks.
I can tell that the SparkPost SDK only looks at CC and BCC if it's being given a dictionary of recipients; if it's given a recipient list ID, it'll ignore the CC and the BCC.
:param list|dict recipients: List of email addresses, or a dict:
``{'address': {'name': 'Kyla', 'email': '[email protected]' }}``
:param str recipient_list: ID of recipient list. If this is set,
the `recipients` param will be ignored
.......
if recipients and not isinstance(recipients, dict):
model['recipients'] = self._extract_recipients(recipients)
recipients = model['recipients']
cc = model.pop('cc', None)
if cc:
headers = content.setdefault('headers', {})
headers['CC'] = ','.join(cc)
cc_copies = self._format_copies(recipients, cc)
recipients.extend(cc_copies)
bcc = model.pop('bcc', None)
if bcc:
bcc_copies = self._format_copies(recipients, bcc)
recipients.extend(bcc_copies)
These lines of code aren't executed b/c recipient list ID is treated as a dict so they bypass that chunk of code. The CC/BCC are still part of the payload but is apparently ignored.
