AgentMail SDK

AgentMail is an API-first email platform built for AI agents. Unlike transactional email APIs (Resend, SendGrid) that focus on one-way sending, AgentMail provides full two-way email inboxes that agents can create, send from, receive into, and manage programmatically.

Key capabilities:

• Instant inbox creation (milliseconds, no domain setup needed)
• Two-way conversations with native thread management
• Reply extraction (extracted_text) strips quoted history automatically
• WebSocket and webhook support for real-time inbound
• Human-in-the-loop drafts for agent oversight
• Multi-tenant isolation with pods
• Allow/block lists for sender filtering
• IMAP and SMTP access for legacy integrations

Installation and setup

# Python
pip install agentmail
