This script automates sending WhatsApp messages to multiple contacts using the pywhatkit library. It reads contact details from a CSV file and sends a specified message to each recipient. A delay is added between messages to prevent rate limits.

Ensure you have the required libraries installed:

pip install pywhatkit pandas

The script imports the following modules:

import pywhatkit  # For sending WhatsApp messages
import pandas as pd  # For reading the CSV file
import time  # For adding delays between messages

• The script reads a CSV file (contacts.csv) containing contact details.
• Expected CSV format:

  phone,message
  712345678,Hello, how are you?
  798765432,Good morning!
  

• The phone column should contain recipient numbers (with or without a country code).
• The message column should contain the message to be sent.

1. Reading Data

   data = pd.read_csv("contacts.csv")

   • Reads the contact list from the CSV file.

2. Processing and Sending Messages

   for index, row in data.iterrows():
       try:
           receiver = str(row["phone"]).strip()
           if not receiver.startswith("+"):
               receiver = "+254" + receiver  # Adds the country code if missing
           message = str(row["message"])
           pywhatkit.sendwhatmsg_instantly(receiver, message)
           print(f"Message sent successfully to {receiver}")
           time.sleep(60)  # Adds a delay of 60 seconds
       except Exception as e:
           print(f"Error: {e}")

   • Iterates through each contact.
   • Ensures the phone number has the correct format.
   • Sends the message using pywhatkit.sendwhatmsg_instantly().
   • Waits 60 seconds before sending the next message.

1. Phone Number Format: Ensure the phone column contains valid numbers. Missing country codes are automatically prefixed with +254.
2. Rate Limiting: A 60-second delay is added to prevent spam detection.
3. Error Handling: Errors are caught and printed instead of stopping execution.
4. File Path: Ensure contacts.csv is in the correct directory or provide an absolute path.

1. Prepare the CSV File with valid phone numbers and messages.
2. Run the Script

   python whatsapp_message_sender.py

3. Monitor the Output to ensure messages are sent successfully.

This script simplifies bulk messaging via WhatsApp, automating the process efficiently. 🚀
