Connect Codex to Instantly

Give an AI agent your Instantly workspace as a tool and it runs outreach directly instead of describing the steps. It can create a campaign and a lead list, bulk add leads, activate the campaign, count unread emails, and pull campaign analytics, calling each operation as a tool while it works. Wire it into a hosted coding agent in NoClick and it can stand up a cold email campaign and check its numbers unattended.

About Codex

Codex is OpenAI's command-line coding agent. NoClick runs it as a hosted agent and lets you connect your apps to it as tools, turning it from a coding assistant into an operator that can act across your systems. Connect an integration to the agent and Codex can query, create, and update records in that app directly. You keep the Codex experience and give it real reach into the tools your team already uses.

Fast, capable code generation and editing
Good at well-scoped, concrete tasks
Strong at API and data manipulation
Familiar to teams already on OpenAI tooling
