SES client send_email twice time

[EmptyRabbit]

Invoke the send method once and check error log output only print once time, but receive two same email. Has anybody met the same problem?

    def send(self, recipients, subject, text_msg='', html_msg='', cc_recipients=None):
        logging.error(f'Sending {subject} mail...')
        try:
            resp = self.client.send_email(
                Destination={
                    'ToAddresses': recipients,
                    'CcAddresses': cc_recipients or []
                },
                Message={
                    'Body': {
                        'Html': {'Charset': 'utf-8', 'Data': html_msg},
                        'Text': {'Charset': 'utf-8', 'Data': text_msg}
                    },
                    'Subject': {'Charset': 'utf-8', 'Data': subject},
                },
                Source=self.sender
            )
            logging.error(resp)
            return resp['MessageId']
        except Exception as ex:
            logging.error(f'[{self}]send error, {ex}')
            return None

Hi @EmptyRabbit, thanks for reaching out. It looks like this might overlap with this post on re:Post. To check if it's something related to the retry mechanism, could you verify if the duplicate messages have the same MessageId?

Only my email received duplicate SES mail, and I check SES client only send mail once time (only one MessageId log output) . Maybe something wrong with my email config, thanks
