How do you mail on the same thread

I think you meant to ask "How do you mail on the same thread?"

To mail on the same thread, you can use the mail function in Python, which allows you to send emails using a single thread. Here's an example:

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

def send_email(subject, message, from_addr, to_addr, password):
    msg = MIMEText(message)
    msg['Subject'] = subject
    msg['From'] = from_addr
    msg['To'] = to_addr

    server = smtplib.SMTP('smtp.gmail.com', 587)
    server.starttls()
    server.login(from_addr, password)
    server.sendmail(from_addr, to_addr, msg.as_string())
    server.quit()

# Create a thread for each email
threads = []

for i in range(5):
    subject = f"Email {i+1}"
    message = f"This is email {i+1}"
    from_addr = "[email protected]"
    to_addr = "[email protected]"
    password = "your_password"

    t = threading.Thread(target=send_email, args=(subject, message, from_addr, to_addr, password))
    threads.append(t)
    t.start()

# Wait for all threads to finish
for t in threads:
    t.join()

In this example, we define a function send_email that sends an email using the smtplib library. We then create a list of threads, each of which calls the send_email function with different email details. We start each thread using the start method, and then wait for all threads to finish using the join method.

By using threads, we can send multiple emails concurrently, which can improve the performance and efficiency of our email sending code.
