AI Email Recognition

NOTE

This feature is supported from version v1.1.0

This feature is inspired by the Alle project

Features

The AI email recognition feature uses Cloudflare Workers AI to automatically analyze incoming email content and intelligently extract important information, including:

• Verification Code (auth_code) - OTP, security code, confirmation code, etc.
• Authentication Link (auth_link) - Login, verify, activate, password reset links
• Service Link (service_link) - GitHub, GitLab, deployment notifications and other service-related links
• Subscription Link (subscription_link) - Unsubscribe, manage subscription links
• Other Link (other_link) - Other valuable links

Extraction results are automatically saved to the metadata field in the database, and the frontend can directly display extracted verification codes or links.

Configuration Variables

Variable Name	Type	Description	Example
ENABLE_AI_EMAIL_EXTRACT	Text/JSON	Whether to enable AI email recognition feature	true
AI_EXTRACT_MODEL	Text	AI model name, choose from models supporting JSON mode	@cf/meta/llama-3.1-8b-instruct

Content Length Limit

To avoid AI model token limits, the maximum email content length for processing is 4000 characters. Email content exceeding this limit will be truncated before AI analysis.

Workers AI Binding

Configure Workers AI binding in wrangler.toml:

[ai]
binding = "AI"

Or add in Cloudflare Dashboard Worker settings:

• Variable name: AI
• Type: Workers AI

Address Allowlist (Optional)

To control costs and resource usage, you can configure an address allowlist in the Admin console's AI Extract Settings page:

Configuration

• Allowlist Disabled: AI extraction will process all email addresses
• Allowlist Enabled: AI extraction will only process addresses in the allowlist

Allowlist Format

One address per line, supporting wildcard * to match any characters:

• Exact Match: user@example.com - Only matches this specific email
• Domain Wildcard: *@example.com - Matches all emails under example.com domain
• User Wildcard: admin*@example.com - Matches emails starting with admin
• Wildcard Anywhere: *test*@example.com - Matches emails containing test
• Multiple Wildcards: admin*@*.com - Matches emails starting with admin under any .com domain

Configuration Example

user@example.com
*@mydomain.com
admin*@company.com

This configuration will only perform AI extraction for:

• user@example.com (exact match)
• All emails under @mydomain.com (e.g., test@mydomain.com, admin@mydomain.com)
• All emails starting with admin under @company.com (e.g., admin@company.com, admin123@company.com)
