How send Asyncronous email using Azure Communication Email python sdk

Question

I tried sending email using Azure email communication Email, it works fine until I need to implement asyncronous sending email since its used multiple time and the response is really slow

class Email(Configuration):
def __init__(self):
    super().__init__()
    self.logger_file = 'email_exception.log'

async def send_mail(self, email_content: dict, email_recipient: str = None):
    print(f" sending email called")
    error = False
    message = "Success"
    recipient_address = email_recipient
    if email_recipient is None or email_recipient == '':
        recipient_address = os.getenv("RECIPIENT_EMAIL_ADDRESS")

    try:
        content = {
            "senderAddress": sender_address,
            "recipients":  {
                "to": [{"address": recipient_address}, {"address": recipient_address}],
                "cc": [{"address": recipient_address}],
                "bcc": [{"address": recipient_address}]
            },
            "content": email_content
        }
        client = EmailClient.from_connection_string(connection_string)

        poller = client.begin_send(content)

        print(f" polllerrrr {poller}")

        time_elapsed = 0
        while not poller.done():
            await poller.wait(POLLER_WAIT_TIME)
            time_elapsed += POLLER_WAIT_TIME

            if time_elapsed > 18 * POLLER_WAIT_TIME:
                raise RuntimeError("Polling timed out.")

        if poller.result()["status"] == "Succeeded":
            print(
                f"Successfully sent the emails (operation id: {poller.result()['id']})")
            # logging.info(f"Successfully sent the email ")
            return error, message
        else:

            raise RuntimeError(str(poller.result()["error"]))

    except Exception as ex:
        self.logger.error(
            f"exception was thrown when sending email {str(ex)}")
        error = True
        message = str(ex)
        return error, message

However, I got exception object NoneType can't be used in 'await' expression, though its successfully sending email, I think it not acting asyncrounously since its throwing exception, any ideas?

How to send Asynchronous email using Azure Communication Email Python SDK

You can use the below sample code to send Asynchronous emails using Azure Communication Email Python SDK.

Code:

import os
from azure.communication.email import EmailClient
import asyncio

async def send_email():
    connection_string = "your-connection string"
    client = EmailClient.from_connection_string(connection_string)

    sender_address ="<sender address>"
    recipient_address = "<recipient address>"

    email_message = {
        "subject": "This is the subject",
        "plainText": "This is the body",
        "html": "<html><h1>This is the body</h1></html>"
    }

    email_content = {
        "senderAddress": sender_address,
        "recipients": {
            "to": [{"address": recipient_address}],
        },
        "content": email_message
    }

    try:
        poller = client.begin_send(email_content)
        result = poller.result()
        if result:
            print(f"Email sent with ID: {result['id']}")
        else:
            print("Error sending email: result is None")
    except Exception as ex:
        print(f"Error sending email: {str(ex)}")

async def main():
    await send_email()

if __name__ == "__main__":
    asyncio.run(main())

Output:

Email sent with ID: 50cfeb24-6660-4cf5-a07e-xxxxxxx
