Mailing system for Telegram

Hello! I have reviewed your technical specifications. The task is clear, and I have experience in developing such automation systems (Userbots) in Python.

Since you requested a structured response according to the points in the document, I am sending my proposal:

1. Revisions and Optimization of Technical Specifications (Technical Suggestions)

As a specialist, I see several "bottlenecks" that should be considered for stability:
Delay Mathematics (Critical): The specifications indicate a sending interval of 1 hour (60 min) and a random delay of 10-90 seconds.
Problem: If we take an average delay of 50 seconds * 50 chats = 2500 seconds (42 min). If it approaches 90 seconds, the sending will take 75 minutes, which will break the hourly schedule.
… Solution: Either reduce the interval to 10-40 seconds, or (which is better) implement multithreading: sending goes in parallel from 2-3 accounts. This will reduce the risk of banning and fit into the schedule.
Proxy: The specifications do not mention proxies. For the operation of the account pool (point 4), it is critically important to use mobile proxies for each session; otherwise, Telegram will quickly link all accounts together and ban the entire network. I will add SOCKS5 support.
Admin Panel: Instead of a web panel (which is more expensive to develop), I propose to implement an Admin-Bot on Aiogram. This is more convenient (management directly from the phone), cheaper, and fully meets the needs (statistics, logs, management).

2. Project Roadmap
I will carry out the work in stages:
Architecture: Setting up Docker, preparing the database (SQLite/PostgreSQL), configuring Pyrogram to work with MTProto.
Core (Connector): Implementation of account addition (session management), authorization, session validity check.
Logic (Scheduler & Queue): Writing a scheduler (APScheduler or Celery) with logic for day/night modes and message queue.
Anti-spam System: Implementation of "soft" delays, handling FloodWait errors, account rotation.
Interface: Creating an Admin-bot for managing texts, chats, and viewing logs.
Testing and Deployment: Launching in a Docker container on your server, stress test.

3. Estimation (Time and Budget)
The calculation is based on creating a reliable system that will not "crash" after a week.
Stage 1: Connector and Database
Term: 1-2 days.
Cost: ~2000 UAH.
Stage 2: Sending Logic, Scheduler, Anti-spam
Term: 2-3 days.
Cost: ~4000 UAH.
Stage 3: Admin Panel (Telegram Bot) and Configuration
Term: 1-2 days.
Cost: ~2500 UAH.
Stage 4: Tests, Docker, final configuration
Term: 1 day.
Cost: ~1500 UAH.
Overall:
⏳ Terms: 5-7 working days.
💰 Budget: 10,000 UAH (for the complete "turnkey" project with support at the start).
