Email marketing from your codebase.

Connect nitrosend to OpenAI Codex via MCP. Your email stack lives next to your code. Same agent, same context, same workflow.

$ codex mcp add nitrosend -- npx -y @nitrosend/mcp
Quick start

Up and running in three steps.

Step 1

Install the MCP server

Run codex mcp add nitrosend. Codex registers the bridge and pulls the package via npx.

Step 2

Sign in with OAuth

On first call, Codex opens the nitrosend sign-in flow. Sign in once. The connection persists.

Step 3

Prompt Codex

Tell Codex what emails your app needs. It reads your code, understands your users, builds the campaigns.

Try it

Example prompts for Codex.

Transactional

"Use Nitrosend to set up transactional emails for signup confirmation, password reset, and invoice receipt. Reference my User model for the fields."

Onboarding

"Use Nitrosend to build a 5-email onboarding series based on our app's key features. Space them out over 14 days."

Migration

"Use Nitrosend to import our contacts from the Mailchimp export in /data/contacts.csv and recreate our existing segments."

Debugging

"Use Nitrosend to check our email deliverability. Are SPF, DKIM, and DMARC configured correctly? What's our bounce rate?"

Analytics

"Use Nitrosend to pull the last 10 campaigns and correlate performance with subject line length and send time."

Refactor

"Use Nitrosend to replace our old Mailgun transactional code. Wire up the equivalent nitrosend calls and keep the same template variables."

Why it works
