Email marketing from Claude.

Connect nitrosend to Claude Cowork (claude.ai) via MCP. The platform disappears into the tab you already have open.

Quick start

Connected in under a minute.

Step 1

Add a custom connector

In Claude Cowork, open Settings, Connections, Add Custom Connector. Paste https://api.nitrosend.com/mcp.

Step 2

Sign in with OAuth

Authenticate with your nitrosend account. No API key to manage. OAuth keeps the connection fresh.

Step 3

Start talking to it

Ask Claude to draft a campaign, pick the segment, schedule the send. It runs the platform for you.

Try it

Just ask Claude.

Launch campaign

"Use Nitrosend to write a product update email for our SaaS users. Friendly tone. Mention the new dashboard. Send to active-users."

Build a flow

"Use Nitrosend to set up a 3-email welcome series. First immediately after signup, second at 2 days, third at 5 days."

Manage contacts

"Use Nitrosend to create a segment of users who signed up in the last 30 days but haven't opened any emails yet."

Check performance

"Use Nitrosend to show how our last 3 campaigns performed. Open rates, click rates, and any trends."

Rewrite copy

"Use Nitrosend to update the Q4 newsletter. Make the subject punchier and cut the intro in half."

Testing

"Use Nitrosend to send me a test of that one so I can see it in my inbox before we ship."

nitrosend is the fastest email platform that works where you work. Prompt it from Claude. Trigger it from your code. Let it run your email marketing while you build your product.

It's not an email tool with AI features. It's an AI that does your email marketing.

We're obsessed with speed. Not because speed is trendy, but because speed is the thing that separates the people who ship things that change lives from the people who plan to ship. Every minute you spend configuring email automations is a minute you're not talking to customers, writing code, or selling.

We believe the best tools disappear into your workflow. You shouldn't have to learn our interface.

We're George, Ed and Kam, and we're building nitrosend because the world has shifted and email hasn't caught up. Until now - welcome to faster email.
