Email marketing from
your codebase.
Connect nitrosend to OpenAI Codex via MCP. Manage your email stack alongside your code — campaigns, contacts, automations, all from the same agent that writes your software.
$ codex --mcp nitrosend=npx:-y:@nitrosend/mcp
Your code ships features. Your agent ships emails.
Codex already understands your codebase — your data models, your user flows, your business logic. With nitrosend connected, that same agent can set up the transactional emails your app needs, build onboarding flows that match your user journey, and create campaigns that reflect what your product actually does.
No context switching between your code editor and an email dashboard. No copy-pasting merge tags. Codex reads your code, understands your users, and talks directly to nitrosend's API via MCP. The email platform becomes part of your development workflow.
One command to install. Your API key connects the two. Then just tell Codex what emails your app needs and it builds them.
Up and running in three steps.
Add the MCP server
Run this command to connect nitrosend as an MCP tool in Codex.
$ codex --mcp nitrosend=npx:-y:@nitrosend/mcp
Set your API key
Export your nitrosend API key as an environment variable.
$ export NITROSEND_API_KEY=nskey_live_...
Prompt Codex
Tell Codex what emails your app needs. It reads your code, understands the context, and builds the campaigns.
Example prompts for Codex.
"Look at my User model and set up transactional emails for signup confirmation, password reset, and invoice receipt."
"Build a 5-email onboarding series based on our app's key features. Space them out over 14 days."
"Import our contacts from the Mailchimp export in /data/contacts.csv and recreate our existing segments."
"Check our email deliverability. Are SPF, DKIM, and DMARC configured correctly? What's our bounce rate?"
Everything your app needs to send email.
Full-stack email
Transactional and marketing email on one platform. Separated streams for deliverability. No need for two providers.
Code-aware context
Codex reads your codebase. It knows your data models, routes, and user flows. Your emails match what your product actually does.
BYO infrastructure
Bring your own sending (SES, Mailgun) and AI keys for maximum control. Or use nitrosend's managed infrastructure. Your choice.
Ship features. Ship emails. Same agent.
One command to install. Free to start. Your email stack lives alongside your code.
$ codex --mcp nitrosend=npx:-y:@nitrosend/mcp
