Stripe Projects - Nitrosend

Nitrosend is a provider on Stripe Projects. One command creates or links a Nitrosend account, provisions a sending brand with an API key and a hosted sender, writes the credentials to your .env, and lets you pick, upgrade and downgrade tiers from the terminal. Everything the CLI creates is an ordinary Nitrosend account you can open in the dashboard.

Availability depends on Stripe listing Nitrosend in the Projects catalog. Until then, use the regular dashboard and API key flow.

Quickstart

stripe plugin install projects
stripe projects init
stripe projects add nitrosend/email --config '{"company_name":"Acme Coffee","website":"https://acme.example"}'
stripe projects env --pull

add returns NITROSEND_API_KEY, NITROSEND_API_URL, NITROSEND_MCP_URL, NITROSEND_BRAND_SID and NITROSEND_FROM_ADDRESS. The sender is hello@<company>.nitrosend.net, reserved for you and activated on your first send; no DNS is needed. If you omit company_name, the CLI asks for it before the sender can be reserved.

stripe projects llm-context points your coding agent at the Nitrosend agent guide: the variables, the MCP connection and the first send.

Accounts

Linking needs no browser. Stripe verifies the email on your Stripe account, and the link is made in one step:

New to Nitrosend. That email gets a Nitrosend account, owned by you, with the normal dashboard access.
Already a Nitrosend user. The account you administer is linked. If you administer several, the CLI asks which one.
Already paying Nitrosend directly. Your plan and card stay as they are; change the plan in the dashboard.

A Stripe account links to one Nitrosend account, so teammates working on the same Stripe account work on the same Nitrosend account.

stripe projects unlink nitrosend removes the link and keeps the account.

Tiers and billing

Tiers are the public Nitrosend plans: Free, Pro and Ultra. Every tier has unlimited contacts; agent and API calls are not metered. Enrichment and email validation are metered per use on every tier.

stripe projects upgrade nitrosend      # pick pro or ultra
stripe projects downgrade nitrosend    # back to free

A paid tier is charged to the card on your Stripe Projects billing profile through a Shared Payment Token. Nitrosend runs the subscription in its own Stripe account with that token as the payment method, so the first charge and every renewal stay inside your Stripe Projects spending limit and show in stripe projects spend. An upgrade is charged the difference at once. Ultra costs more than the default Stripe Projects spending limit, so raise your limit in your Stripe account settings before choosing it. The dashboard shows the plan and routes plan changes back to the CLI.

Credentials

stripe projects rotate nitrosend/email issues a new API key; the previous key keeps working for 24 hours. stripe projects remove nitrosend/email deprovisions the resource: the key is revoked after a grace period, the brand and its content stay, and the account stays.

Sending from your own domain

The hosted sender needs no DNS. To send from your own domain, open Settings > Domains in the dashboard, add the domain, publish the records it prints, and select it. Both senders can coexist.

Stripe customer data

Nitrosend can also import the customers, subscriptions and invoices from the Stripe account you build on and turn them into segments, merge fields and flow triggers. See Stripe.

Dashboard

stripe projects open nitrosend prints a one-time sign-in link to the dashboard for this account. The link expires after five minutes and works once.
