What this workflow does

This workflow reads incoming emails asking about company info in your tech store. It then turns the email text into a short summary, checks if it is a company info query, finds related knowledge from a database, and writes a clear reply email. Finally, it sends the reply automatically to the person who wrote the email.

It solves the problem of spending too much time answering many detailed questions by hand. The result is faster, more accurate, and consistent answers that make customers happy.


Who should use this workflow

This workflow is for business owners or support teams who get lots of complex emails asking about store opening hours, products, deliveries, discounts, and company programs. If writing replies takes hours or sometimes misses info, this workflow helps.

It works best where questions are varied but related, and a knowledge base exists to answer them.

Customization ideas

  • Add more categories in the Email Classifier node to handle sales, support, or other inquiries automatically.
  • Replace DeepSeek R1 with other AI models like GPT-4 for different summary styles or languages.
  • Regularly update your Qdrant knowledge base by adding new documents using Google Drive nodes and embedding models.
  • Extend workflow to process email attachments and archive them or scan with AI.
  • Adjust AI prompt texts in drafting and review nodes to support other languages or tone preferences.

Common issues and solutions

Problem: “Failed to Connect to IMAP Server”

Cause is usually wrong credentials or IMAP not enabled in the email account.

Check credentials in n8n’s credential manager and verify IMAP settings on your email provider’s site.


Problem: “No Emails Classified as Company Info Request”

The classifier’s system prompt or categories may not match incoming emails.

Edit and test the classifier prompt for exact category names and sample email texts.


Problem: “Unable to Retrieve Data from Qdrant”

Check if the Qdrant collection name is correct and API keys are valid.

Regenerate API credentials if expired and test connection again.
