Mailing to groups
33 USD Technical Task
Project Goal
It is necessary to develop a console application for Windows that sends messages to Telegram groups using pre-prepared Telegram sessions.
Main Requirements
1. Authorization
The software must work through the Telegram Session.
2-3 ready Telegram sessions will be provided for testing.
2. Launch
The launch is performed through CMD (Windows command line).
After launching, the program should immediately start execution or offer the necessary launch parameters.
3. Interface
A graphical interface is not required.
All work is done entirely through the console.
In real-time mode, it is necessary to display:
connection to each Telegram session;
current account status;
to which group the message is being sent;
successful message sending;
errors during sending;
reasons for skipping a group (if any);
completion of work.
Logs must be clear and readable.
4. Project Delivery
After completing the development, it is necessary to provide:
ZIP archive of the project;
full source code;
a file with instructions for launching;
a list of necessary libraries and dependencies (if used).
Testing
Development is considered complete after successful testing on the provided Telegram sessions and confirmation of correct operation.
In the feedback, please indicate:
what language the project will be written in;
which libraries will be used;
estimated completion time;
experience with Telegram API and Telegram Session.

I have reviewed the technical task — the task is clear, I have experience, and I am ready to take it on.
Language: Python
Libraries:
Telethon — working with Telegram API through sessions (.session files)
asyncio — asynchronous sending through multiple accounts
colorama — colored, readable output in the console
loguru — structured logs
…
What will be implemented:
Loading ready .session files without reauthorization
Asynchronous work with multiple accounts simultaneously
Detailed real-time logs: connection, account status, sending to each group, errors, reasons for skipping
Handling FloodWait, bans, group unavailability
Launching via CMD with parameters (path to sessions, text, list of groups)
ZIP with source files, README, and list of dependencies
Experience: worked with Telegram API through Telethon, specifically with ready sessions and mass mailings.
Deadline: 2–3 days after the start.
I am ready to discuss details — the number of groups, the format of the list, whether a delay is needed between sends.

Good day! I have reviewed the technical assignment. The task is completely clear, and I am ready to implement console software for sending messages to groups via Telegram sessions.
I am answering your questions for feedback:
Development language: Python.
Libraries: Telethon (works excellently and stably with .session files) or Pyrogram, as well as colorama for beautiful, clear, and readable logging in the Windows console (CMD) in real time.
Estimated timeframe: 1–2 days including testing on your sessions.
…
Experience: I have experience working with the Telegram API and account automation. The logic of working with sessions, bypassing limits, and handling errors (FloodWait, flood ban, skipping groups) is completely familiar to me.
Upon completion, I will deliver the project strictly according to your requirements: a ZIP archive with clean source code, a requirements.txt file with all dependencies, and a detailed instruction manual (README.md).
I am ready to discuss the details, receive test sessions, and start working.

Hello, I worked on a Telegram bot for automatic messaging — sending messages to 500+ groups through sessions, with logging of each step and error handling.
I will write the project in Python using the Telethon library — it is perfect for working with Telegram Session files. The logs will be colorful and readable directly in CMD.
An interesting question: are the sessions already authorized in the groups, or do we also need to implement automatic joining of groups before sending messages?
I suggest we get in touch; I will provide you with free technical consultation and we can create a development plan + I will tell you about my team!

Hello.
I have experience in developing solutions that work through the Telegram API and Telegram Session, including multithreaded systems, automation, handling a large number of accounts, and utilities without a graphical interface.
For this project, the optimal solution will be Python with the Telethon library. It provides stable operation with Telegram Session, supports asynchronous processing, convenient logging, and allows for easy scaling of the project in the future.
The console application will display the entire process in real-time: connecting each session, account status, current group, successful message sending, reasons for skipping (if any arise), possible errors, and the final result of execution. The logs will be structured and easy to analyze.
After the development is completed, we will provide a ZIP archive of the project, the full source code, instructions for running it via CMD, as well as a list of all necessary libraries and dependencies for quick deployment.
…
The estimated implementation time is 2 to 4 working days after receiving the test Telegram sessions and clarifying the format of the list of groups and messages.
