mails: An Email Automation Workflow Tool for AI Agents

mails is an email workflow tool for AI agents, offering a clean desktop application and command-line interface to help agents send, receive, and process emails programmatically, lowering the technical barrier to email automation. Its core philosophy is 'simplicity', focusing on the Windows platform to provide a lightweight, zero-configuration solution for AI developers and users with automation needs.

Email remains a core channel for business communication, customer service, and system notifications. With the rise of AI agents, enabling agents to handle emails autonomously has become an urgent need. However, the complexity of email protocols (IMAP/SMTP), diverse authentication methods, and differences between service providers have set barriers for developers. mails addresses this pain point with an out-of-the-box solution.

mails is built around three core capabilities:

• Email Sending: Supports single/group sending, rich text/plain text formats, attachment handling, and custom sender information;
• Receiving and Reading: New email detection, content extraction, sender/subject information retrieval, and body parsing;
• Organization and Classification: Thread grouping, sender filtering, keyword tagging, and status tracking (read/unread/replied).

mails is suitable for various automation scenarios:

• Customer Support Automation: AI monitors support mailboxes, analyzes sentiment and urgency, generates reply drafts, or assigns to human agents;
• Status Notification Bots: Sends alert emails when systems are abnormal, and status reports when tasks are completed;
• Email Data Extraction: Regularly scans inboxes to extract order/invoice information and sync to databases or CRMs;
• Keyword-Triggered Workflows: Automatically creates tickets, sends replies, or initiates approval processes when emails with specific keywords are received.

mails supports integration with mainstream email service providers and offers multiple authentication methods: app passwords, OAuth login, API access, and universal IMAP/SMTP protocols. For enterprise mailboxes with multi-factor authentication, it supports app passwords or OAuth flows to avoid complex login challenges.

First-time Setup:

1. Download the Windows version;
2. Unzip (ZIP format) or run directly (EXE format);
3. Configure email account information;
4. Select an authentication method (app password/OAuth/IMAP/SMTP);
5. Specify the inbox folder to monitor;
6. Complete basic permission configuration.

Daily Use: Check new emails, read content to extract information, send replies, save sender/subject data, classify emails by rules, and execute fixed-sequence operations.

Applicable Scenarios: Personal/small team email automation, AI agent email function expansion, rapid prototype verification, Windows environment workflows.

Inapplicable Scenarios: Large-scale enterprise email system management, advanced email security requirements, cross-platform needs (Windows-only), complex email routing and filtering rules.

mails focuses on core needs and provides a simple, reliable email automation solution to help developers focus on business logic rather than infrastructure building. As an email component in the AI agent toolchain, it fills the gap between general platforms and specific needs. We look forward to expanding to more platforms and features in the future.
