Bring team email into your workflow
Nestiel is building a developer surface for people and AI agents alike: an Email API, an MCP server, Skills, and a CLI — programmable send, receive, conversation queries, and send-task orchestration.
Email API
Flat POST routes, JSON body, and Bearer auth covering send, receive, conversations, and send tasks.
MCP server
Expose inbox capabilities over the Model Context Protocol so AI agents like Claude can read, query, and trigger sends.
Skills
Package flows like 'follow up with a customer' or 'bulk reply' into reusable skills agents can call.
CLI
Log in, send, search, and manage send tasks from your terminal for scripting and automation.
In development
The core product already delivers full send/receive, conversations, AI, send tasks, and deliverability health. The developer surface is under design; docs and examples will land here once interfaces are ready.
