Sabbir Ahmed Chowdhury — Sat, 01 Nov 2025 08:42:04 +0000

I created an automated payment reminder and collection workflow that helps businesses stay on top of overdue invoices with zero manual effort. 💡

💰 The system automatically generates a Stripe payment link, then shortens it for easy sharing.

📱 After 7 days, they receive an SMS reminder(Twilio).
💬 After 14 days, a Slack message alerts the collection team to follow up.

And here’s the best part — once a payment is made, the Stripe signature is verified for authenticity to ensure every transaction is genuine before updating records. ✅

Automation + security = peace of mind. ⚙️

Social Media(Facebook, Instagram, Linkedin) Auto-Posting with n8n based on niche!

Sabbir Ahmed Chowdhury — Sat, 25 Oct 2025 13:14:11 +0000

I recently built a n8n automation that takes care of everything from creating social media content to posting it automatically on Facebook, Instagram, and LinkedIn! 🧠✨

Here’s how it works 👇

📝 Step 1: Create Captions & Images Automatically

The user selects a niche (like travel, tech, fitness, etc.).

AI then creates a unique caption and image for that niche using Gemini and Stable Diffusion(Stability AI).

Everything is saved into a Google Sheet with status “Created” and action “Not Posted.”

The user reviews it and marks it “Approved” when it’s ready to go live.

⏰ Step 2: Auto-Post on Schedule

On a scheduled time, n8n checks Google Sheets for posts marked as “Approved.”

It then automatically posts them on Facebook, Instagram, and LinkedIn.

Once done, the sheet updates the status from “Not Posted” → “Posted.”

💡 What’s cool?
Everything happens automatically — from idea to live post! It’s perfect for anyone managing multiple pages or looking to save time with smart automation.

🧩 Tools I used:

n8n for workflow automation
Google Sheets for review and approval
Gemini AI for captions
Stable Diffusion(Stability AI) for images

I’m really happy with how it turned out — smooth, efficient, and scalable!
🚀

Email Outreach & Sentiment Detection Automation

Sabbir Ahmed Chowdhury — Wed, 24 Sep 2025 07:35:21 +0000

I’ve built an Email Outreach & Sentiment Detection Automation in n8n that completely streamlines the process of sending outreach emails, tracking replies, and analyzing sentiment with AI.

🔹 How it works

Outreach Automation

The workflow kicks off on a daily schedule and selects 5–10 leads from a Google Sheet.

It loops through the selected contacts and sends out personalized outreach emails via Gmail.

Each sent email is logged back into Google Sheets with a status update (Sent) for full tracking.

Reply Monitoring

A second workflow runs every 15 minutes to check for new unread replies.

It extracts the required fields (sender, subject, body, etc.) and checks if the email is indeed a reply to the outreach.

The content is cleaned up by removing quoted text, extra strings, and special characters so only the fresh reply remains.

Sentiment Detection with AI

The cleaned reply is passed to an AI Agent powered by Google Gemini with Simple Memory and a Structured Output Parser.

The AI evaluates the reply and categorizes it (e.g., Positive, Neutral, Negative).

The result, along with the reply text, is logged back into Google Sheets with status = Replied.

🔑 Why this is powerful

✅ Outreach volume is controlled (5–10/day for natural delivery)
✅ Automated logging of sent & replied emails in Google Sheets
✅ AI-powered sentiment detection ensures quick triage of responses
✅ Scalable & hands-free – from sending, monitoring, cleaning, to analyzing replies

This automation essentially acts as a virtual SDR assistant — sending outreach, logging every action, and telling you instantly whether replies are positive or not.

From Spreadsheet to Inbox: Automated Lead Emails Made Easy with n8n

Sabbir Ahmed Chowdhury — Sun, 21 Sep 2025 07:07:53 +0000

An n8n automation workflow to simplify lead outreach with personalized HTML emails!

🔹 How it works:

Lead Upload – Start by selecting a leads file (CSV, XLS, or XLSX) via form input.

Google Drive Integration – File is uploaded to Google Drive for safe storage, then automatically downloaded for processing.

Smart File Handling – A Switch node detects the file type (CSV, XLS, XLSX) and routes it to the correct parser.

Data Extraction – Lead details (name & email) are extracted from the chosen file format.

Field Selection – Workflow ensures only the required fields are mapped for email sending.

Loop Processing – Iterates over each lead one by one.

Automated Email Sending – Sends personalized HTML emails to every lead using Gmail (or other email integrations).

✅ With this setup, You can upload any type of lead file, and the system handles everything—from storage and parsing to automated outreach—without manual intervention.

This workflow makes lead management scalable, efficient, and error-free.

AI-powered Customer Knowledge Base Assistant!

Sabbir Ahmed Chowdhury — Sun, 14 Sep 2025 10:34:15 +0000

Workflow 1: Website Scraping & Data Storage:
This workflow automates the process of collecting and preparing knowledge for an AI support agent:

Trigger: Starts when clicking "Execute workflow."
Fetch Links: Retrieves site links from a Google Sheet.
Loop & Scrape: Iterates through each link and scrapes the website data.
Vectorization: Converts scraped content into embeddings using OpenAI embeddings.
Data Storage: Stores the vectorized data in Pinecone vector database for semantic search.
Update Status: Marks the link as processed in the Google Sheet. This ensures that all customer-facing knowledge is continuously updated and accessible in a structured format.

Workflow 2: AI-Powered Customer Support Agent:
This workflow uses the stored knowledge to answer queries in real time and integrates with multiple tools for enhanced support:

Trigger: Starts when a chat message is received.
AI Agent: Uses the stored embeddings in Pinecone to understand the query and retrieve the most relevant information.
Context & Memory: Maintains conversational memory with Simple Memory and uses the OpenAI Chat Model for natural responses.
Actions: o Fetch user query data from Pinecone for context. o Send meeting details via email. o Add events to calendar for client meetings. o Send Slack notifications to the team. This makes the support agent not just a responder, but a proactive assistant that can handle scheduling, notifications, and knowledge-based answers seamlessly.

With these workflows combined, we have:
✔ Automated web scraping and knowledge management
✔ AI-powered customer support with contextual memory
✔ Multi-channel integrations (Email, Calendar, Slack)
✔ Scalable and efficient workflow automation
