Connect Nitrosend to Claude Cowork (claude.ai) via MCP, drafting and sending in your brand's own colors, fonts and tone. The platform disappears into the tab you already have open.
In Claude Desktop or Cowork, go to Settings → Connectors, search for Nitrosend and click Connect. On claude.ai, open claude.ai/directory/nitrosend and click Connect.
Authenticate with your Nitrosend account. No API key to manage. OAuth keeps the connection fresh.
Ask Claude to draft a campaign, pick the segment, schedule the send. It runs the platform for you.
"Use Nitrosend to write a product update email for our SaaS users. Friendly tone. Mention the new dashboard. Send to active-users."
"Use Nitrosend to set up a 3-email welcome series. First immediately after signup, second at 2 days, third at 5 days."
"Use Nitrosend to create a segment of users who signed up in the last 30 days but haven't opened any emails yet."
"Use Nitrosend to show how our last 3 campaigns performed. Open rates, click rates, and any trends."
"Use Nitrosend to update the Q4 newsletter. Make the subject punchier and cut the intro in half."
"Use Nitrosend to send me a test of that one so I can see it in my inbox before we ship."
You use claude.ai to draft copy, think through campaigns, plan strategy. Now Claude can execute the idea, not just write about it.
Nitrosend's Brand Kit learns your colors, fonts and tone from your own site once. Every email Claude drafts here already looks and sounds like you.
DKIM, SPF, DMARC auto-configured. Transactional and marketing streams separated. Infrastructure you don't need to think about.
Every plan includes unlimited contacts. You pay for sends, not storage. Import your entire list for free.
The connector exposes the same email API your product would call directly, so a campaign Claude sends and one your backend triggers travel the same path. When the work belongs in a script or a deploy step rather than a conversation, the command line interface reaches the same endpoints.
The connector is one of several surfaces. Developers wire the same MCP server into VS Code and Windsurf, and marketers who live in a chat window use the ChatGPT app instead. All of them are listed on the integrations page.
Nitrosend is a listed connector for Claude for the same reason this page exists: composing and sending email is moving from a person in a dashboard to an agent in a chat, and Nitrosend is the platform built for that shift, not an ESP with a chat window bolted on afterward.
