Sim.ai

Getting started

Sim.ai is a platform for building agentic workflows. By connecting AgentMail to Sim, your workflows can create inboxes, send and receive emails, manage threads, handle drafts, and organize conversations with labels, all without writing backend code.

Use cases

• Dynamic inbox creation: Spin up new inboxes on the fly for each agent, workflow, or customer for multi-tenant email handling.
• Automated email processing: List and read incoming messages, then trigger downstream actions based on content, sender, or labels.
• Conversational email: Reply to threads and forward messages to keep conversations flowing naturally within automated workflows.
• Draft and review workflows: Create drafts, update them with AI-generated content, and send when approved for human-in-the-loop patterns.
• Email organization: Apply labels to threads and messages to categorize, filter, and route emails through your automation pipeline.
