How can I create a Python script to ping multiple IP addresses and send email notifications to multiple recipients when any of the IPs are down?

import subprocess
import platform
import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart

def ping_host(ip):
   # Determine the appropriate ping command based on the platform
   if platform.system().lower() == "windows":
       command = ['ping', '-n', '1', ip]  # Windows syntax
   else:
       command = ['ping', '-c', '1', ip]  # Unix-like syntax
   
   try:
       subprocess.run(command, check=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
       return True  # If the ping is successful, return True
   except subprocess.CalledProcessError:
       return False  # If the ping fails, return False

def send_email(subject, body, receiver_emails):
   sender_email = "[email protected]"
   password = "**********"

   message = MIMEMultipart()
   message["From"] = sender_email
   message["To"] = ", ".join(receiver_emails)  # Join receiver emails with comma
   message["Subject"] = subject

   message.attach(MIMEText(body, "plain"))

   with smtplib.SMTP_SSL("smtp.gmail.com", 465) as server:
       server.login(sender_email, password)
       server.sendmail(sender_email, receiver_emails, message.as_string())

def main():
   # List of IP addresses to ping
   ip_addresses = ['36.255.68.153', '36.255.68.111', '36.255.71.132']
   
   # List of receiver email addresses
   receiver_emails = ["[email protected]", "[email protected]"]

   # Ping each IP address and print whether it's up or down
   for ip in ip_addresses:
       if ping_host(ip):
           print(f'{ip} is UP')
       else:
           print(f'{ip} is DOWN')
           subject = f'Alert: {ip} is DOWN'
           body = f'The IP address {ip} is not reachable.'
           send_email(subject, body, receiver_emails)
           

if __name__ == "__main__":
   main()

my code is above. sometimes it gives correcrt and sometimes it gives incorrect results.
