Your email marketing team is already in Claude Cowork.
You already use Claude Chat on claude.ai to think through ideas, draft copy, and plan strategy. With nitrosend connected, Claude Cowork can take those ideas and execute them — create the campaign, design the email, pick the segment, schedule the send.
Most email platforms force you out of your workflow into a dashboard you have to learn. nitrosend flips that. The platform disappears into the claude.ai browser tab you already have open.
Connect once. Then just talk to Claude Cowork about what you want to send, who you want to reach, and when. nitrosend handles the infrastructure — deliverability, authentication, compliance, tracking — so you can focus on the message.
Connected in under a minute.
