Automated SMS Sender Using Selenium and Google Messages

Project Overview

This project is an automated solution designed to streamline the process of sending text messages to multiple recipients. By leveraging web automation, it eliminates the need to manually send each message from a mobile device, saving time and reducing the potential for errors.

Key Features

• Automated Messaging: Sends SMS messages through Google Messages Web by automating browser interactions.
• Excel Integration: Reads recipient numbers and personalized messages from an Excel file (MasaSMS.xlsx), making it easy to manage and update the messaging list.
• Status Tracking: Updates the Excel file with timestamps after each message is sent, providing a clear record of successful deliveries.
• User Guidance: Provides prompts to assist the user in connecting their Google Messages account, ensuring a smooth setup process.

Technologies Used

• C# Console Application: The core program is written in C# programming language, offering a robust and efficient foundation.
• Selenium WebDriver: Automates browser actions, simulating user interactions to send messages via the web interface.
• Google Chrome Automation: Utilizes Chrome with remote debugging to control the browser programmatically.
• ClosedXML Library: Handles reading from and writing to Excel files without the need for Microsoft Excel to be installed.
• Microsoft.Extensions.Configuration: Manages application settings through a JSON configuration file (appsettings.json), allowing for easy customization and scalability.
• P/Invoke for Windows API: Interacts with the Windows operating system to manage console window behavior.

How It Works

1. Initialization: The application launches Google Chrome with remote debugging enabled and prompts the user to connect to Google Messages Web.
2. Configuration Loading: Reads settings from appsettings.json, including browser paths, CSS selectors for web elements, and timing intervals.
3. Excel Processing: Opens the MasaSMS.xlsx file to retrieve phone numbers and corresponding messages.
4. Message Dispatch Loop:
   • Checks each entry to determine if the message has already been sent.
   • Navigates through Google Messages Web using Selenium:
     • Initiates a new chat.
     • Inputs the recipient's phone number.
     • Types the message content.
     • Sends the message.
   • Logs the date and time of sending in the Excel file.
5. Completion: Closes the browser and terminates the application after all messages are sent.

Why This Project Is Valuable

Automating the sending of SMS messages is highly beneficial for businesses and organizations that need to communicate with a large audience. Whether for marketing campaigns, event notifications, or updates, this tool simplifies mass messaging while maintaining personalization.

Challenges Addressed

• Web Element Interaction: Devised methods to reliably locate and interact with dynamic web elements on Google Messages Web.
• Timing and Synchronization: Implemented appropriate delays and checks to ensure web pages and elements are fully loaded before interaction.
• Data Integrity: Ensured that the Excel file is accurately read and updated, preventing duplicate messages or missed entries.

Potential Enhancements

• Error Handling Improvements: Incorporate more robust exception handling to manage network issues or unexpected changes in the web interface.
• User Interface Upgrade: Develop a graphical user interface (GUI) to make the application more accessible to users without technical backgrounds.
• Platform Independence: Adapt the application to work with other messaging platforms or extend compatibility beyond Windows.

Conclusion

This project demonstrates the effective use of automation to handle repetitive tasks efficiently. By combining C#, Selenium WebDriver, and Excel integration, it offers a practical solution for mass communication needs. It's an excellent example of how programming and automation can be harnessed to improve productivity and streamline workflows.
