How can I send emails asynchronously in Python?

You can use the asyncio library along with aiohttp or smtplib to send emails asynchronously. Would you like a code example?

Yes, please provide a code example.

Here's a simple example using smtplib and asyncio:

import asyncio
import smtplib
from email.mime.text import MIMEText

async def send_email(subject, body, to):
    msg = MIMEText(body)
    msg['Subject'] = subject
    msg['From'] = '[email protected]'
    msg['To'] = to

    loop = asyncio.get_event_loop()
    await loop.run_in_executor(None, lambda: smtplib.SMTP('smtp.example.com').send_message(msg))

async def main():
    await send_email('Hello', 'This is a test email', '[email protected]')

asyncio.run(main())

This code sends an email asynchronously. Let me know if you have any questions!

What if I want to send multiple emails at once?

You can modify the main function to create a list of tasks for sending multiple emails concurrently. Here's an example:

async def main():
    tasks = [send_email('Subject', 'Body', f'recipient{i}@example.com') for i in range(5)]
    await asyncio.gather(*tasks)

This will send five emails at the same time.
