To write ad copy using Klaviyo metrics, find your email campaigns with the highest open and click rates. Your subject lines from these campaigns are proven winners with your audience. Feed these exact subject lines into an AI model to draft Meta ad copy variants that use the same hooks your audience already loves. This process turns your best-performing email content into a reliable source for paid ad creative.

The Real Problem: Your Best Data is Trapped

You know the answer is in your data. You have Klaviyo campaigns that crushed it. The open rates were huge, the click-throughs were clean, and they drove sales. That subject line, that hook, that angle, it all worked.

So what happens next?

You download a CSV. You open another tab for ChatGPT. You copy and paste the subject lines, trying to give the AI enough context. It gives you back something generic. You edit it, paste it into Meta Ads Manager, and hope for the best.

Or worse, you assign this to a VA for $1,000 a month. Now you're managing them, explaining the goal, checking their work, and dealing with timezone delays. You're spending more time managing the task than it would have taken to just do it yourself.

You're drowning in tasks that should be automatic.

Stop Babysitting Workflows. Get a Coworker.

Sterling is an AI coworker that lives in the Slack you already use. It’s not another tool to learn or a workflow you have to build and fix. You connect your apps, like Klaviyo and Meta, then you just tell it what to do in plain English.

It does the work.

For $50 a month, Sterling can connect to your Klaviyo account, identify your top-performing subject lines, and draft a dozen Meta ad copy variations based on those proven hooks. Your $50 plan includes 20,000 tokens, which is more than enough to handle your weekly performance reports, draft ad campaigns, and summarize customer feedback without you ever leaving Slack.

Frequently Asked Questions

1. How is this different from just using ChatGPT?

ChatGPT tells you what to do, then you have to go do it. Sterling is connected to your business systems, so it does the work for you. It pulls the real data, drafts the real content, and waits for your one-tap approval to move forward.

2. Is my Klaviyo and Meta data secure?

Yes. Sterling runs on Google Cloud and scales itself. Secrets are never logged, and every action that writes or changes data in another system stops and asks for your permission first.

3. What happens if I use all my tokens?

We send you a heads-up in Slack when you hit 80% of your monthly tokens. You can top up with 10,000 more for just $25. No surprise bills, ever.

4. Can Sterling actually post the ads for me?

No. For safety, Sterling will never take an action like spending your money or publishing an ad without your explicit, manual approval. It does all the prep work and hands you the finished draft, ready for you to launch.

5. Does this really only cost $50 a month for my whole team?

Yes. It's $50 a month for unlimited seats. We don't do per-seat pricing. Give your entire team a coworker that does the busywork.

6. Can't I just build this with Zapier?

You can try. But then you own the workflow. You have to build it, test it, and fix it every time something breaks. Or, you can type one message and let Sterling own the whole loop.
