Emailien — Email Automation Tool

AI-powered email personalization and bulk sending

The Problem

During my internship search, I needed to send personalized emails to many companies. Manually writing each email was time-consuming and inefficient. I needed a tool that could:

  • Send bulk emails efficiently
  • Personalize each email automatically
  • Handle email templates
  • Track sent emails
  • Be simple to use

The Approach

I built a Python-based email automation tool that uses AI for personalization:

Key Components:

  2. AI Personalization: Used AI to generate personalized content for each recipient
  3. Bulk Sending: Implemented batch email sending with proper delays
  4. Contact Management: Simple CSV-based contact list management
  5. Tracking: Basic logging of sent emails

Technologies Used:

Python SMTP OpenAI API CSV Processing

Python Logic

Core Workflow:

  1. Load contact list from CSV file
  2. Read email template
  3. For each contact:
    • Extract contact details (name, company, email)
    • Use AI to personalize template
    • Replace placeholders with actual data
    • Send email via SMTP
    • Log the sent email
    • Add delay to avoid spam filters
  4. Generate summary report

Key Features Implemented:

  • Template variable replacement ({{name}}, {{company}}, etc.)
  • AI-powered content personalization
  • Error handling for failed sends
  • Rate limiting to prevent blocking
  • Simple command-line interface

A small business owner was receiving many similar inquiry emails daily but couldn't respond quickly enough. They needed:

  • Instant responses to common questions
  • Organized tracking of all inquiries
  • Automatic categorization of emails
  • No manual email checking required

The Automation Design

I designed a simple n8n workflow that automatically handles incoming emails:

3. Check for keywords (pricing, support, demo, etc.)
        ↓
4. IF keyword found:
   → Select matching template
   → Personalize with sender name
   → Send auto-reply
        ↓
5. Log to Google Sheets:
   → Timestamp
   → Sender email
   → Subject
   → Keyword matched
   → Response sent
        ↓
6. Send notification to business owner
              

Response Templates Created:

  • "Pricing" keyword → Pricing information email
  • "Support" keyword → Support contact details
  • "Demo" keyword → Demo scheduling link
  • "General" → General acknowledgment
