How to Connect Klaviyo to Claude for Direct-Response Campaign Drafting
Description: How to safely feed email metrics into an AI model to draft high-converting email sequences directly inside your team's Slack thread.
You can't connect Klaviyo directly to Claude's API. You need a secure tool to act as a bridge for your data. Sterling CoWorker is that bridge, built directly into your Slack workspace. It lets you feed real-time Klaviyo performance metrics into Claude to draft entire email campaigns with a single message, no manual data exports needed.
The Real Problem: Manual Work and Bad Data
You're trying to use AI to write better emails. Good. But the process is a mess.
Right now, you’re probably downloading a CSV of your last campaign’s performance from Klaviyo. Then you open another browser tab for Claude, paste in a messy prompt, and try to feed it the data without leaking customer information. You get a draft, copy it, go back to Klaviyo, paste it, and then spend 20 minutes reformatting everything.
It's a clunky, insecure workflow that wastes your time on things that should be automatic. You're trying to make Zapier and ChatGPT do backflips, and it breaks half the time. Or worse, you’re paying a VA $800 a month to do this copy-paste work, and you still have to micromanage the entire process.
There is a better way. A coworker that just does the work.
For $50 a month, Sterling connects your tools, runs the analysis, drafts the campaign, and waits for your approval in Slack. Your starting 20,000 tokens are enough to analyze your weekly performance and draft 8-10 complete, multi-email campaign sequences. No surprise bills. No babysitting required.

| The Old Way (VA / Intern) | The DIY Way (Zapier + AI) | The Sterling Way |
|---|---|---|
| $600–$1,100 a month | Tab fatigue from switching apps | $50 a month, unlimited seats |
| Weeks of training and onboarding | You build and babysit the flows | Set up in an afternoon |
| Timezone delays and micromanagement | Breaks when an API changes | Runs on Google Cloud, never sleeps |
| Gone in 3 months (interns) | No approval gate for actions | Every write waits for your one tap |
Your First Delegation: Klaviyo to Claude in 5 Minutes
You can delegate your first campaign draft before you finish your coffee. Here’s how.
1. Add Sterling to Slack. No servers, no IT, no new software for your team to learn. 2. Connect Klaviyo. Follow the one-time prompt in Slack to authorize access. Your data lives in Google's secured cloud and is never logged. 3. Type your request. Go to your marketing channel and type a direct command. For example:
@Sterling, analyze the performance of our last 3 campaigns in Klaviyo. Identify the top-performing subject line style and the lowest-performing CTA. Then, using our brand voice, draft a 3-email win-back sequence for customers who haven't purchased in 90 days.
4. Review and Approve. Sterling will post the analysis and the complete email drafts right in the thread. Read them over. If you like what you see, tap the "Approve" button. If you want a change, just reply in the thread: make the second email's subject line shorter.
That’s it. The task is done. No CSVs, no context switching, no babysitting a workflow. You get back to running your business.
