How to write prompts for Klaviyo AI - A Best Practise Guide

You've got Klaviyo humming away in the background, tracking clicks, purchases, and email opens like a champion. Your data's all there. But here's the problem: you're drowning in dashboards.

You don't have time to dig through reports, decode segment logic, or become a prompt engineer just to figure out which customers are about to churn. You need answers fast: preferably in plain Eng-lish.

Good news: Klaviyo's AI features (and tools like ChatGPT) are finally making it possible to have an actual conversation with your data. No SQL degree required.

In this guide, I'll show you exactly how to talk to Klaviyo AI like a pro, so you can get instant insights, build smarter campaigns, and stop wasting time buried in spreadsheets.

Why natural language AI changes the game

You're time-poor. You've got a thousand tabs open and you need to make a quick call on whether to send a campaign today or wait until Friday.

  • Which customer segment should I target next? 
  • Why did my last email perform badly?
  • Who's most likely to buy again this month?

The problem isn't the data: it's how you access it. Traditional platforms force you to manually build segments, filter reports, and decode metrics. It's exhausting.

That's where natural language AI changes the game. Instead of navigating complex menus, you just describe what you need. Klaviyo's Segments AI and conversational tools like ChatGPT let you ask questions like a human and get answers like a data analyst.

It's digital marketing for small business owners who'd rather focus on strategy than spreadsheets.

The 3 Golden Rules of Prompting Klaviyo AI

Here's the truth: AI is only as good as the instructions you give it. Most people write vague, wishy-washy prompts and then wonder why the output is rubbish.

Follow these three rules, and you'll get better results every single time.

1. Be Direct (No Fluff)

AI doesn't need you to be polite or creative. It needs you to be specific.

Bad Prompt:

"Can you help me understand my email performance

Good Prompt:

"Show me open rates, click rates, and revenue for all email campaigns sent in January 2026. Compare to December 2025."

See the difference? The second prompt tells the AI exactly what to deliver. No guessing, no wasted output.

2. Give Context (Your Data + Your Goal)

AI doesn't know your business. You need to give it context so it understands what matters.

Bad Prompt:

"Create a segment for high-value customers."

Good Prompt:

"Create a segment of customers who spent over $500 in the last 90 days, opened at least 3 emails, and haven't purchased in the last 30 days. I want to send them a VIP discount."

The more context you provide (timeframes, behaviours, goals), the better the AI performs. This is especially critical when using Klaviyo's predictive analytics to forecast churn or lifetime value.

3. Request Action (Tell It What to Do Next)

Don't just ask for data: ask for a recommendation or next step.

Bad Prompt:

"What's my cart abandonment rate?"

Good Prompt:

"My cart abandonment rate is 68%. Suggest three automated flow improvements to reduce this by 15% in the next 60 days."

This shifts the AI from reporter to strategic advisor. It's the difference between getting a number and getting a plan.

Your Klaviyo AI Prompt Cheat Sheet

Here's a collection of ready-to-use prompts organised by task type. Copy, tweak, and deploy these in your Klaviyo dashboard or via ChatGPT integrations.

Reporting Prompts

Use these to pull insights fast without clicking through endless tabs.

  • "Show me revenue from email campaigns in Q4 2025 broken down by month."
  • "Which flows generated the most revenue last month? Rank them."
  • "Compare average order value from email subscribers vs non-subscribers over the last 90 days."
  • "Identify customers who opened 5+ emails but never purchased."

Strategy Prompts

These help you make smarter decisions about who to target and when.

  • "Create a segment of customers who purchased red wine in the last 90 days but haven't engaged with our last two campaigns."
  • "Suggest three re-engagement campaign ideas for subscribers who haven't opened an email in 6 months."
  • "Which customer segment has the highest predicted lifetime value? Build a VIP nurture sequence for them."
  • "Identify customers most likely to churn in the next 30 days and recommend a winback flow."

This is where Klaviyo's Segments AI really shines. Instead of manually building filters, you describe the audience in plain English, and the platform does the heavy lifting.

Creative Prompts

Use AI to speed up content creation and testing.

  • "Write 5 subject line variations for a flash sale on winter jackets. Make them urgent but not spam-my."
  • "Generate email body copy for a welcome series targeting first-time buyers in the travel industry."
  • "Suggest 3 SMS messages for a browse abandonment flow. Keep them under 160 characters and include a discount code."
  • "Create dynamic product recommendations based on customers who bought hiking boots in the last 60 days."

Pro tip: If you're running a B2C marketing strategy with frequent promotions, AI-generated content saves hours every week. Just make sure you review it before sending: AI isn't perfect (yet)

Troubleshooting: How to Avoid AI Hallucinations 

Let's talk about the elephant in the room: AI sometimes lies.

It's called "hallucination," and it happens when AI confidently delivers information that's completely made up. This is especially dangerous when you're making business decisions based on those out-puts.

Here's how to catch and fix it

1. Cross-Check Numbers Against Your Klaviyo Dashboard

If AI tells you your open rate is 45% but your dashboard says 32%, trust the dashboard. Always verify key metrics manually.

2. Ask for Sources

When using tools like ChatGPT, ask: "Where did you get this data?" or "Show me the calculation." If it can't explain, the number might be dodgy.

3. Be Specific About Date Ranges

Vague timeframes ("recently," "last month") confuse AI. Always use exact dates: "January 1–31, 2026."

4. Test Segments Before Sending

If AI builds a segment for you, preview the customer list before you launch a campaign. Make sure the logic matches your intent. Klaviyo's Segments AI is powerful, but you're still the strategist.

5. Use AI for Ideas, Not Final Decisions

Treat AI as your research assistant, not your CEO. It's great at generating options, spotting patterns, and drafting copy: but the final call is always yours.

At Walk Digital, we help SMEs set up Klaviyo implementations that combine AI power with human strategy. Because at the end of the day, tools don't win campaigns: smart decisions do

Why Strategy Beats Tools Every Time

Here's the thing most people get wrong: they obsess over the tech and forget about the strategy.

Klaviyo AI can predict churn, personalise send times, and generate email copy. But if you don't have a clear key messaging customer journey map or a solid email marketing strategy, AI won't magically fix your campaigns.

AI amplifies what you already do. 

If your flows are broken, AI will help you break them faster. If your segmentation is lazy, AI will give you lazy results. If your integrations are not working correctly, automations won’t trigger.

That's why at Walk Digital, we always start with strategy first:

  • Who are you ideal customers?
  • What's your ideal customer journey? 
  • Where are the biggest drop-offs?
  • What are the actions that will drive conversions

Once we've mapped that out, then we deploy AI to automate, optimise, and scale. It's the difference between throwing spaghetti at the wall and building a system that actually works.
