Good day! I was working on such a connection — Google Sheets as a database, personalized emails with variables from the rows, auto-statuses on contacts, and responses from the Telegram bot pulled back into the table for the appropriate client.

One practical question: should the mailing be sent from your Gmail/Workspace (there's a limit of ~2000 emails/day + spam risk) or through a separate service like SendGrid? This affects deliverability and settings. And is there already a Telegram/Viber bot or should it be built from scratch?

I am ready to take this on, approximately 7 days.

Budget: 2250 PLN Deadline: 12 days

Good day.

I have built similar connections: Google Sheets as a source of contacts, personalized mailing with tracking, lead collection via a Telegram bot. Here’s how I envision the implementation in blocks.

Google Sheets — Service Account via gspread. You share the spreadsheet with the service account and that’s it. The system reads the contacts, substitutes variables (name, company, direction) into email templates, and automatically records processing statuses back into the spreadsheet.

Mailing — Gmail API, HTML templates via Jinja2. Limit: 500 emails/day on a free account, 2000/day if Workspace. Delay between emails is adjustable to avoid spam filters. Open tracking is done with a transparent 1x1 pixel with a unique ID, clicks through redirect links. Bounce detection is automatic. The sending log is recorded in a separate sheet of the spreadsheet.

Telegram bot on aiogram 3.x. In each email, a personal deep link to the bot with the contact identifier. The client clicks, the bot identifies them by the row in the spreadsheet, records the transition, collects responses. The lead is forwarded to the manager with a contact card (company, direction, history).

I will connect Viber in the second phase. Business account verification takes 2-4 weeks, so we start with Telegram as the main channel. The architecture is shared, Viber will work in parallel after verification.

Control panel — web interface on FastAPI with authorization. Template editor, start/stop campaigns, real-time statistics: sent, opened, clicks, transitions to the bot, leads. Everything in Docker, can be deployed on any server.

Stack: Python, gspread, Gmail API, aiogram 3.x, FastAPI, SQLite, Jinja2, Docker.

Timeline 12 days:
Week 1 — Sheets integration + mailing with tracking + Telegram bot
Week 2 — panel + Viber preparation + testing + documentation

Question: how many contacts are currently in the database and what type of email account are you using (free or business)? Expand

Budget: 1150 PLN Deadline: 14 days

Good day, Serhiy.
I have reviewed the project.
I would divide it into separate parts (integration with Telegram / integration with Viber / control panel).

Regarding implementation, I see it this way:
Stack: Python + gspread (Google Sheets API) + Gmail API + aiogram 3.x for the Telegram bot (it can be hosted on Railway to minimize costs).

Logic: rows are read sequentially from the table (triggered), variables (name, company, direction) are substituted into the email template, emails are sent via Gmail API with frequency control and delivery logs, and the processing status is returned back to the same row in the table.

Each email will contain a personal deep link to the Telegram bot; after clicking, the bot identifies the contact by ID, updates the status, receives the client's response, and forwards the lead to the manager with the contact card.

Viber will be addressed in the second stage — verifying the business account will take a few weeks (if you do not have a business profile), so it is advisable to start with Telegram as the main channel, and connect Viber on the same architecture after verification.

The control panel (templates, open/click statistics) is also a separate stage after MVP, so the budget initially goes to a working communication channel rather than the interface.
I have experience with similar connections: Google Sheets + personalized mailing + Telegram bot with lead tracking — I am ready to show examples in personal messages.

I look forward to collaborating with you on such an interesting project. Expand

Hello! I have reviewed your task regarding the creation of an automated communication system (Google Sheets -> Email -> Telegram).

This task perfectly fits my stack. I specialize in creating reliable and asynchronous Python bots and API integrations. I do not create "one-off scripts"; I build stable systems that can run for months on servers (Linux VPS) without failures.

Here’s how I propose to implement it (Stack):

Base: Python (using asyncio for speed, so the mailing does not hang).

Integration: Google Sheets API (via service account) + Telegram Bot API (library aiogram 3.x).

Logic: The script will regularly (via cron or apscheduler) check the table, generate personalized emails (via Gmail API or SMTP), send them, and, in case of a transition to the bot, automatically update the status in the table.

Recently, I developed a complex architecture for a trading bot that works with heavy APIs, artificial intelligence integration (LLM), and outputting results. You can check the quality of my code on GitHub: https://github.com/hvoi/Testnet-binance-vision-AI

Do you already have a prepared Google account (or Workspace) for setting up the API, or will assistance be needed with this from scratch? I am ready to discuss the details and start working. Expand

Glory to Ukraine! Death to the enemies!

Sergiy, good day! I regularly work with Python automation and Telegram bots (specifically integrations via Telethon), so your case — Sheets → Email → Telegram/Viber — is a familiar architecture for me.

Approach:
— Google Sheets as the source of contacts via a service account (gspread), processing statuses are written back to the table automatically
— Personalized email distribution via Gmail API with templates (name, company, direction), control of limits and delays against spam filters, log of sends and delivery errors
— Telegram bot with a unique deep link for each contact in the letter — the bot immediately identifies the client by the row in the table, records the transition and response, forwards the lead to the manager with the contact card
— Simple control panel for templates and statistics

I am ready to start with the Telegram part (the most critical for transitioning to a permanent channel), while simultaneously setting up the Sheets+Email layer.

Please let me know: how many contacts are in the current database, and is immediate integration with Viber needed, or can we start with Telegram and add Viber in the second stage? Expand

Budget: 6000 PLN Deadline: 19 days

Hello. Our team specializes in developing B2B automation and integrating Telegram ecosystems into sales departments. I have reviewed the task. We will not be creating clunky macros on Google Script.

For stable scaling, we will deploy a reliable microservices architecture:
1. Backend (Python/aiogram): It will create a seamless gateway between Google Sheets API, Gmail API, and the Telegram bot. It will automatically pull variables and generate personalized emails.
2. Control panel (TMA): Instead of awkward third-party sites, we will develop an admin panel as a Telegram Web App (React). Your department head will be able to open the dashboard directly in the messenger: edit templates, see the funnel (opens/clicks), and receive leads.

We implement systems that reduce managers' routine and convert cold leads into money. If you are looking for a reliable turnkey solution, not a "one-time script" - write to me. I will propose a detailed data exchange architecture and provide budget guidance.

Budget: 1500 PLN Deadline: 8 days

Hello.

I can develop a tool for automated work with a B2B database: Google Sheets -> personalized email -> transition to Telegram/Viber bot -> recording status and lead.

Proposed approach:
- connection to Google Sheets and reading the client database;
- message templates with variables: name, company, direction, additional fields;
- launching the mailing with restrictions to avoid sending everything chaotically;
- log of sent messages, delivery errors, statuses for each contact;
- Telegram bot for receiving responses/applications and forwarding to the manager;
- recording interaction history back into Google Sheets;
- simple panel or management through a table, depending on what will be more convenient for your team.

Stack: Python or Google Apps Script for logic, Google Sheets/Gmail API, Telegram Bot API. Viber Business Messages can be connected as a separate step after clarifying access and rules for your account.

Estimated timeline: 8 days for a working version with basic logic, testing, and a short instruction.
Cost: 1500 PLN.

Before starting, I need to clarify: from which email should the mailing be sent, what is the size of the database, what statuses are needed in the table, and whether there is already a ready Telegram/Viber bot. Expand

Budget: 1100 PLN Deadline: 10 days

Good day, Serhiy. The stack for your task: Python (gspread for Google Sheets API, aiogram 3 for Telegram bot, Gmail API or SendGrid for mailing with limits and logging). Each contact in the table receives a personalized email with variables (name, company, industry) + a unique deep link in the bot - after clicking, the bot automatically identifies the contact, updates the status in Sheets, and forwards the lead to the manager. Control panel: editing templates, start/stop campaigns, statistics of sends/opens/clicks - all through a separate tab in the table or a simple web interface. One question: is the mailing going from your Gmail/Workspace or do you need a separate SMTP (SendGrid) for a larger volume without the risk of blocking?

Budget: 1500 PLN Deadline: 10 days

Hello! I am interested in your project. I specialize in Python development and business process automation, so your task fits perfectly with my stack.
I understand your ultimate goal: to create not just a "spam tool," but a managed lead generation funnel, where Google Sheets serves as a convenient database, and a Telegram bot is the follow-up tool.
1. Regarding examples of completed projects:
I am currently in the process of setting up my public portfolio, so I do not have open links to ready-made similar systems. However, I have solid practical experience in developing multifunctional Telegram bots and integrating external APIs. I am ready to provide snippets of my code or demonstrate their architecture in personal messages so you can assess my level.
2. Proposed technology stack:
I suggest implementing the core of the system in Python, as it is the most stable option for scaling:
Database: Google Sheets API (gspread library).
Mailing: Gmail API (or a reliable SMTP server) to ensure a high level of delivery.
Bot: Telegram Bot API (aiogram library for asynchronous and fast operation).
Note: I propose to move the Viber Business API to stage 2.0 (after testing the MVP on Telegram) to speed up the launch of the main system.
Control panel: Can be implemented through an admin panel in the Telegram bot itself for the manager, or as a lightweight web interface (Flask).
3. Estimated timelines and stages:
The overall timeline for implementing the basic system (MVP) is 7-10 days.
Since the project is complex, I suggest working in stages (sprints) with payment for each stage:
Stage 1 (2-3 days): Integration of Google Sheets and automation of email mailing according to the template.
Stage 2 (3-4 days): Development of the Telegram bot, generation of unique links for clients, and linking the bot to the spreadsheet.
Stage 3 (2-3 days): Creation of the control panel, testing error logs, and project delivery.
I am ready to discuss details, budget, and start working. Please message me for agreement on the terms of reference! Expand

Hello! The project description is very clear and understandable, and the task is right up my alley. I specialize in automating business processes and creating custom CRM tools, so I will ensure everything is reliable and hassle-free for your managers. For implementation, I suggest using Python with the gspread library for connecting to Google Sheets and aiogram for developing the Telegram bot. We will deploy the entire mailing and tracking script on a reliable cloud server (VPS) so that everything runs autonomously 24/7. This is much more stable than Google Apps Script, which has strict daily limits on sending emails. For the mailing itself, we will connect the Gmail API or a professional SMTP server like SendGrid to ensure that emails reach clients and do not end up in spam. Convenient columns with interaction statuses such as "Sent", "Opened", or "Moved to bot" will appear directly in your table. To ensure flawless logic, we will generate a unique referral link in the bot (deep link) for each client in the database. As soon as a person clicks on it, the bot will instantly identify the company, update the status in the table, and immediately send a notification to the manager in the work chat. For analytics on email opens, we will embed an invisible tracking pixel, and all clicks on links will go through our redirect script, so all conversion statistics will be automatically collected on a separate dashboard.

Hello!

Your task is well-suited for building an automated communication funnel, and I have already implemented similar solutions based on Google Sheets, Make.com, Telegram bots, CRM, and email automation.

For this project, I would suggest the stack: Google Sheets + Make.com + Gmail API + Telegram Bot API + ActiveCampaign (or similar) + Looker Studio for analytics. This architecture will allow for automatically pulling contacts from the spreadsheet, personalizing emails through variables, launching email campaigns, tracking opens and clicks, and after interest, transferring the client to the Telegram bot with source and lead status tracking.

Relevant case studies include:
— Built an AI consultant and automated communication through Chatfuel, Voiceflow, ActiveCampaign, and Make.com with full data synchronization between channels.
— Implemented a CRM ecosystem based on Zoho/Pipedrive + Make.com, where leads were automatically processed, communication scenarios were launched, and analytics were generated in Looker Studio.

I can also implement a dashboard for launching campaigns, editing templates, and monitoring interaction statuses with each contact.

Estimated implementation time: 7–14 days depending on the need for Viber Business API integration and the complexity of lead processing logic.

Please let me know if there is already a Telegram/Viber bot, or if it also needs to be created from scratch? Expand

Hello!

I specialize in the development of automated systems of various complexities. I am ready to implement your project quickly and in accordance with all requirements.

I suggest we discuss the details: please message me privately.

Budget: 1200 PLN Deadline: 8 days

Good day, Serhiy.

Your task is exactly my profile: automation on Python + Google Sheets + Telegram bots + API integrations. I have working examples (not descriptions — live demos):

• Telegram bot on Python (message generation/processing, response handling): github.com/tpsyyyyyl/content-bot
• Data collection tool + Google Sheets logic + schedule + Telegram alerts: https://price-monitor-bohdan.fly.dev

Proposed stack: Python + Google Sheets API + Gmail API (personalized emails from templates + sending log + error control) + Telegram Bot API (lead transition to bot, linking to contact, passing to manager). Viber — phase 2 (Business API through moderation, so we start with Telegram).

To ensure the tool is stable and scalable (not a one-time solution), I propose 2 phases:

Phase 1 (MVP, core): Google Sheets → personalized email sending from templates + limits/log + Telegram bot captures lead and links to the row in the table + auto statuses of contacts. Approximately 7–9 days.

Phase 2: statistics panel (sent/opened/clicks/responses), Viber channel, improvements based on feedback.

To calculate accurately, please clarify:
1. Estimated size of the database (hundreds/thousands of contacts)?
2. Email — send from your Gmail/Workspace, or a separate SMTP/service?
3. "Email opens" — mandatory? (tracking opens = pixel, not always reliable; I will explain the nuances).

Ready to start Phase 1 immediately after clarifications. Expand

Budget: 1500 PLN Deadline: 13 days

Hello! I have reviewed the technical assignment. The task is fully implemented based on n8n (in conjunction with Google Sheets and messenger APIs). This is the perfect choice for your goal, as n8n allows you to create flexible, visual logic that is easy to scale, add new communication channels, and manage processes without rewriting thousands of lines of code.

Briefly about the workflow:
Table as CRM: n8n monitors the status of the row (for example, "Ready for dispatch"). It picks up variables, sends an individual HTML email, and changes the status to "Sent."
Error control: In case of a delivery error (bounce), n8n automatically tags the row as "Address error."
Deep linking: We embed unique referral links to bots in the email. The client clicks the link ➡️ n8n immediately understands who it is, links their Telegram/Viber with the row in the database, updates the status to "In bot," and notifies the manager.
Admin panel: You will be able to manage email templates directly on the adjacent tab of this same Google Sheet.
My experience: I have ready-made solutions with the connections "Google Sheets + n8n + messengers." Checking statuses and the architecture of referral links for bots is a standard task for me.

Budget: 2050 PLN Deadline: 12 days

I understand the requirements: what is needed is not a one-time sender, but a stable tool over a B2B database in Google Sheets, which takes contacts from rows, forms personalized emails with variables, sends emails, transfers the client to a Telegram or Viber bot, collects responses, and keeps the status and history for each contact, plus a panel for templates, campaign launches, and statistics.

I envision the implementation in Python as a separate service, not on Apps Script. Apps Script quickly hits Gmail limits and poorly maintains states and queues, while a stable, scalable tool is needed here. The service reads and writes Google Sheets through the Sheets API, sends emails via the Gmail API or SMTP with throttling and delivery logs, and returns processing statuses back to the table so you can see everything as usual in Sheets. The Telegram bot on the service side catches transitions via a personal link, binds the user to the row in the database, accepts responses, and forwards the lead to the manager. Viber works similarly through Viber Business Messages.

To prevent the mailing from falling into spam and getting blocked, I plan to implement frequency limits, warming up, and error delivery control with retries. This is a separate aspect that is often underestimated, but it determines whether the emails will reach at all.

Telegram bots and integrations with external APIs are my main work; I manage such services from the requirements to production. I will create a working tool, not a one-time script, with the possibility of further development.

I would like to clarify one thing to calculate accurately: is the mailing going from one of your mailboxes, or do you need several senders for volume rotation? This affects the warming up scheme and throttling.

Hello.

I have experience in developing sales automation systems and client communications using Google Sheets, Google Apps Script, Python, and Telegram Bot API, etc. From similar projects, I have developed a bunch of similar projects as I focus on such projects. Mainly, I create Telegram bots for leads and CRM, like @LeadManager_TGBot.
For your project, I propose using Google Sheets + Google Apps Script for database management, Gmail API for personalized mailings, Telegram Bot API and Viber API for communication, Python (FastAPI) for business logic and event processing, and PostgreSQL for storing interaction history.
As a result, you will get a single tool: client database → automatic personalized mailing → transition to the bot → lead fixation → handover to the manager → funnel analytics.
Estimated timelines:
MVP: 2–5 days.
Full version with analytics and extended logic: 10–12 days.
Cost: $500.

Budget: 2145 PLN Deadline: 15 days

It is correct that you want to launch controlled communication with personalization, status tracking, and transition from email to Telegram/Viber bot using the existing B2B database in Google Sheets, so your department can scale initial contacts without manual routine.
After my work, you will receive an automated outline: mailing with a log, collection of responses and applications, linking contacts to leads in the bot, and transferring them to the manager along with support for the history of interactions and statuses for each row in the table.
I will implement it based on reliable logic for processing rows (idempotency, re-runs without duplication, error control in sending) and collected events (delivery, responses, transitions to the bot) so that campaigns stop correctly and statistics are counted with clear rules.
I have worked on integrations where Google Sheets served as the source of contacts, and the funnel from email was automatically transferred to a chat channel with status tracking and event logging for further work by managers.
I will do it in 52 working hours.
What scenario should be considered a "successful transition to Telegram/Viber": clicking the link in the first message, the fact that the user started a dialogue in the chatbot, or receiving a specific event/response (and how to distinguish repeated transitions from different campaigns)?
Write in DMs, we will agree on tracking rules and starting fields in the table, after which I will immediately structure the work according to your lead funnel scheme.
