Introduction

Sendook is an open-source email infrastructure platform designed specifically for AI agents. Stop wrestling with Gmail APIs, AWS SES configuration, and MIME parsing. Start building intelligent email-powered agents in minutes.

Why Sendook?

Traditional email setup for AI agents is painful:

• Days of configuration: DNS records, SPF, DKIM, DMARC, domain verification
• Complex APIs: Gmail OAuth flows, SES credential management, API rate limits
• Manual parsing: MIME decoding, attachment handling, thread management
• Infrastructure overhead: Polling for emails, webhook setup, storage management

Sendook eliminates all of this complexity with a simple, API-first approach.

Key Features

Everything your AI agent needs to communicate via email:

• Instant Inbox Creation: One API call creates a fully functional inbox. No DNS, no domain setup.
• Real-time Webhooks: Get notified the moment emails arrive. No polling required.
• JSON-Ready Emails: Pre-decoded, formatted emails with parsed attachments. Ready for consumption.
• Send & Reply: Simple APIs for sending emails and replying to threads. Threading handled automatically.
• Full-Text Search: Query emails by any field. Your agent's perfect memory.
• Multi-Inbox Support: Create unlimited inboxes. One per customer, use case, or department.
• Custom Domains: Use your own domains with automatic SPF/DKIM/DMARC setup.
• Open Source: MIT licensed. Self-host or use our cloud. Complete transparency.
