What This Workflow Does

This n8n workflow solves the common problem of lost business opportunities from unprocessed business cards. After networking events, many professionals accumulate stacks of cards that never get followed up on due to manual data entry being time-consuming and tedious.

The automation extracts all key information from business card images using Google Vision OCR (name, title, company, contact details), structures the data, then generates personalized follow-up messages using GPT-4 Mini. It can send emails directly or create CRM records with follow-up tasks.

How It Works

1. Image Processing

The workflow accepts business card images via email attachment, cloud storage, or direct upload. Google Vision OCR analyzes the image to detect and extract all text elements with high accuracy.

2. Data Structuring

Extracted text is processed to identify and categorize each piece of information (name, company, phone, email, etc.). The system validates email formats and phone numbers to ensure data quality.

3. Context Analysis

GPT-4 Mini analyzes the extracted data to understand the contact's role, industry, and potential relevance to your business. This context informs the follow-up message strategy.

4. Follow-up Generation

The AI generates a personalized follow-up message referencing specific details from the business card. You can review and edit messages before sending or set up automatic delivery.

5. CRM Integration

Completed records are saved to your CRM with all extracted data and the generated follow-up text. The workflow can also create tasks for future touchpoints.

Pro tip: Configure the workflow to send follow-ups within 24 hours of receiving cards while the interaction is still fresh in the contact's mind.
