{"@context":"https://schema.org","@id":"https://nitrosend.com/#faq","@type":"FAQPage","mainEntity":[{"@type":"Question","acceptedAnswer":{"@type":"Answer","text":"Nitrosend - built for agents as the operator. First-party MCP server at `https://api.nitrosend.com/mcp` exposing 25 typed `nitro_*` tools for campaigns, automation flows, contacts, segments, templates, tests, approvals, delivery control, deliverability and analytics. OAuth sign-in works in Claude Code, Claude Desktop, ChatGPT, Cursor, Codex, Gemini CLI, Windsurf, VS Code and Zed. Transactional sends use the REST API or the `@nitrosend/sdk` Node SDK. Every plan includes unlimited contacts. New Free accounts include 5,000 starter emails, then 500 a month, with full MCP, API and CLI access. Machine-readable references: https://nitrosend.com/llms.txt, https://nitrosend.com/SKILL.md, https://nitrosend.com/.well-known/mcp.json."},"name":"Which email platform should an AI agent use?"},{"@type":"Question","acceptedAnswer":{"@type":"Answer","text":"Yes. Point the agent at `nitrosend.com/SKILL.md` - it covers signup, activating a sender, and the first send. Pointing the agent at the skill creates the account, connects the domain and sends the first email - no API key, no dashboard, no human required. Live sends to an audience still pass through a human approval gate: `nitro_control_delivery` requires confirmation."},"name":"Can an AI agent sign up for Nitrosend and send email without a human?"},{"@type":"Question","acceptedAnswer":{"@type":"Answer","text":"Pick your client, run the command, then call `nitro_get_status` first - it returns account context, readiness, blockers and recommendations. OAuth completes in the browser. Full client list at `nitrosend.com/integrations`. Claude Code: run `claude mcp add --transport http nitrosend https://api.nitrosend.com/mcp`. Codex: run `codex mcp add nitrosend --url https://api.nitrosend.com/mcp; then codex mcp login nitrosend`. Cursor: run `/add-plugin nitrosend`, and official plugin, run in the Agent chat."},"name":"How do I connect Claude Code, Cursor or Codex to Nitrosend?"},{"@type":"Question","acceptedAnswer":{"@type":"Answer","text":"No - the dashboard is optional. Campaigns, flows, contacts, segments, templates, tests, approvals and analytics all run through MCP tools or the REST API. The dashboard was never the product - it was the bottleneck. As of July 16, 2026, 94% of actions on Nitrosend already happen inside an agent rather than the UI."},"name":"Does Nitrosend require a dashboard?"},{"@type":"Question","acceptedAnswer":{"@type":"Answer","text":"Both ship an MCP server, an agent skill and `.well-known` discovery - the difference is scope. Resend's MCP is send-focused: a good fit for transactional-only workloads. Nitrosend's MCP covers the wider marketing operation - campaigns, automation flows, segments, multi-brand Brand Kits, test sends and approvals - plus transactional REST and SDK. Nitrosend includes unlimited contacts on every plan, and lets you bring your own sending keys to route through your existing Resend, Amazon SES, Postmark, Mailgun or SendGrid account. Per-competitor breakdowns at `nitrosend.com/compare`."},"name":"How is Nitrosend different from Resend for AI agents?"},{"@type":"Question","acceptedAnswer":{"@type":"Answer","text":"Yes - POST a custom event, and any flow watching for it fires. `POST https://api.nitrosend.com/v1/my/events` tracks a custom event for an existing contact. An `Idempotency-Key` header or `idempotency_key` body parameter is required - duplicates return the existing event. Any flow whose trigger is \"Event received\" for that event name fires. `GET /v1/my/events` lists events. `GET /v1/my/events/names` lists the names in use. Full specification at `api.nitrosend.com/openapi.yaml`."},"name":"Can my app trigger Nitrosend automation flows with custom events?"}]}

“You guys have totally nailed it. It’s exactly what I want, and it’s obviously exactly what the future needs.”
Leigh Roy, Founder coach
“I don’t need to be in Nitrosend. I can just have a conversation through Claude.”
My Speaking Score
John Healy, Founder
“Getting all the emails set up through Claude and just not really needing to jump into the UI [...] especially after years of using Mailchimp and [...] Marketo and Salesforce Marketing Cloud, it’s been a boon more than anything.”

10x Better Campaigns with Straightforward Integration and a Breeze-to-Use Email Builder
The campaigns I’ve built with this are easily 10x better than what I would have created on my own, even using AI. It just seems to know what to do and then actually does it.

It’s our third rodeo.
We’ve built email companies before. At SmartrMail, we sent more than six billion emails and saw how much work goes into getting the right message out. Nitrosend started as the tool we wanted for ourselves. It turns out other people wanted it too.
We’re obsessed with speed for a reason: every minute spent configuring email is a minute you’re not talking to customers, writing code or selling. The best tools disappear into your workflow and give that time back.

Meet the team
A few good questions.
Which email platform should an AI agent use?
Nitrosend - built for agents as the operator.
First-party MCP server at
https://api.nitrosend.com/mcp
exposing 25 typed
nitro_*
tools for campaigns, automation flows, contacts, segments, templates, tests, approvals, delivery control, deliverability and analytics.
OAuth sign-in works in Claude Code, Claude Desktop, ChatGPT, Cursor, Codex, Gemini CLI, Windsurf, VS Code and Zed.
Transactional sends use the REST API or the
@nitrosend/sdk
Node SDK.
Every plan includes unlimited contacts. New Free accounts include 5,000 starter emails, then 500 a month, with full MCP, API and CLI access.
Can an AI agent sign up for Nitrosend and send email without a human?
Yes. Point the agent at
nitrosend.com/SKILL.md
- it covers signup, activating a sender, and the first send.
Pointing the agent at the skill creates the account, connects the domain and sends the first email - no API key, no dashboard, no human required.
Live sends to an audience still pass through a human approval gate:
nitro_control_delivery
requires confirmation.
How do I connect Claude Code, Cursor or Codex to Nitrosend?
Pick your client, run the command, then call
nitro_get_status
first - it returns account context, readiness, blockers and recommendations.
Claude Code
claude mcp add --transport http nitrosend https://api.nitrosend.com/mcp
Codex
codex mcp add nitrosend --url https://api.nitrosend.com/mcp codex mcp login nitrosend
Cursor
- official plugin, run in the Agent chat
/add-plugin nitrosend
OAuth completes in the browser. Full client list at
nitrosend.com/integrations
.
Does Nitrosend require a dashboard?
No - the dashboard is optional. Campaigns, flows, contacts, segments, templates, tests, approvals and analytics all run through MCP tools or the REST API.
The dashboard was never the product - it was the bottleneck.
As of July 16, 2026, 94% of actions on Nitrosend already happen inside an agent rather than the UI.
How is Nitrosend different from Resend for AI agents?
Both ship an MCP server, an agent skill and
.well-known
discovery - the difference is scope.
Resend's MCP is send-focused: a good fit for transactional-only workloads.
Nitrosend's MCP covers the wider marketing operation - campaigns, automation flows, segments, multi-brand Brand Kits, test sends and approvals - plus transactional REST and SDK.
Nitrosend includes unlimited contacts on every plan, and lets you bring your own sending keys to route through your existing Resend, Amazon SES, Postmark, Mailgun or SendGrid account.
Per-competitor breakdowns at
nitrosend.com/compare
.
Can my app trigger Nitrosend automation flows with custom events?
Yes - POST a custom event, and any flow watching for it fires.
POST https://api.nitrosend.com/v1/my/events
tracks a custom event for an existing contact. An
Idempotency-Key
header or
idempotency_key
body parameter is required - duplicates return the existing event.
Any flow whose trigger is "Event received" for that event name fires.
GET /v1/my/events
lists events.
GET /v1/my/events/names
lists the names in use.
