Overview

Email Flow is an AI-powered email management app for Shopify merchants. It connects to your email inbox, automatically classifies customer messages, and helps you respond faster with AI-generated replies that understand your customer's order history.

Key capabilities:

Automatic email classification into 10 categories
Customer order history displayed alongside conversations
AI-powered reply suggestions with context awareness
Analytics dashboard for email volume and performance tracking

Email Setup

Email Flow uses IMAP to securely sync your email inbox. You'll need the following information from your email provider:

Provider	IMAP Server	Port
Gmail	`imap.gmail.com`	993
Outlook/Office 365	`outlook.office365.com`	993
Yahoo Mail	`imap.mail.yahoo.com`	993
Zoho Mail	`imap.zoho.com`	993

Gmail App Password

If you use Gmail with 2-factor authentication, you'll need to create an App Password:

Go to your Google Account settings
Navigate to Security → 2-Step Verification → App passwords
Select "Mail" and your device, then click Generate
Use the generated 16-character password in Email Flow

Email Classification

Email Flow's AI automatically categorizes incoming emails into the following categories:

Category	Description
Refund	Requests for refunds or returns
Cancellation	Order cancellation requests
Shipping Issue	Problems with delivery, lost packages
Update Before Shipping	Address changes before order ships
Update After Shipping	Tracking inquiries, delivery updates
Information Request	General product or policy questions
Subscription	Subscription management requests
Prospect	Sales inquiries from non-customers
Spam	Unwanted or irrelevant emails
Neutral	Emails that don't fit other categories

AI Reply Generation

When generating replies, Email Flow's AI considers:

The full email conversation thread
The email's classification category
Customer's Shopify order history (if available)
Product details from recent purchases

AI Model Selection

Email Flow uses different AI models based on the sender:

Premium AI (Claude): Used for verified Shopify customers who have placed orders
Standard AI: Used for unknown contacts and prospects

This ensures your actual customers get the highest quality responses while keeping costs manageable.

read_orders: To display customer order history alongside conversations
