Teach your agent Unitpost, once
The Unitpost skill packages everything a coding agent needs to integrate email correctly the first time — the API shape, the SDKs, scopes, pagination, and send-safety rules — as a skill it loads on demand. One command, and it works with Claude Code, Cursor, Codex, Copilot, Gemini, Windsurf, and 60+ more.

Everything the agent needs to get it right
A skill is documentation the agent loads on demand — not a dependency, not a secret. It teaches how Unitpost works so the agent writes correct integration code from the first try.
The API surface
The /api/v1 resources, prefixed ID scheme (email_…, cmp_…, con_…), request/response shapes, and the OpenAPI spec — so the agent calls real endpoints, not invented ones.
Scopes & auth
How to authenticate with a pk_live_ key and which capability each operation needs, so it asks for the right scope instead of over-provisioning.
Send-safety rules
Confirm before real sends, respect suppressions and verified domains, and never blast a list without a human in the loop.
MCP or REST
When to prefer the MCP server's tools versus raw REST calls, and how the two map 1:1 to the same operations.
Pairs with the MCP server
The skill teaches the agent how to think about Unitpost; the MCP server gives it the tools to act. Install both.
Works with your agent
One skill, every coding agent
The skills CLI auto-detects the agents on your machine and writes the Unitpost skill into each one's skills directory — no per-agent setup.
Start sending email your users actually receive
Create a key, verify a domain, and send your first email in minutes — over the API or right from the dashboard.
