Use Klaviyo's AI to Write Email Campaigns
What This Does
Klaviyo's built-in AI can generate email subject lines, preview text, and body copy — without leaving your email builder. For e-commerce coordinators juggling weekly campaigns, it eliminates the blank-page problem and cuts email drafting time in half.
Before You Start
- You have a Klaviyo account (free tier works)
- You have an email campaign or flow open in the editor
- You know what the email is about (product, offer, segment)
Steps
1. Open the Email Editor
- In Klaviyo, go to Campaigns → click Create Campaign or open an existing draft
- Choose Email as the channel
- Click Design Email to enter the drag-and-drop editor
What you should see: The email template builder with content blocks
2. Use AI to Generate Subject Line
- In the campaign setup screen (before the editor), look for the Subject line field
- Click the Generate subject line button (sparkle icon ✨ or "AI Suggestions" link beside the field)
- You'll see a text prompt: describe your email briefly — e.g., "20% off sale on outdoor water bottles, targeting past buyers"
- Click Generate — Klaviyo produces 5 subject line variations
What you should see: 5 subject line options with different angles (urgency, curiosity, benefit-focused) Troubleshooting: If you don't see the AI button, ensure your account has the feature enabled — go to Settings → Integrations
3. Generate Email Body Copy
- In the email editor, add a Text block
- Click inside the text block → look for the AI writing button (pencil + sparkle icon) in the text toolbar
- A prompt box opens: describe the email body you need — e.g., "Promotional email for summer sale, 20% off all water bottles, friendly and excited tone, include a clear CTA to shop now"
- Click Write → AI generates a draft email body
- Edit to match your brand voice and add specific product links
What you should see: A full email draft in your text block, ready to refine Troubleshooting: If the AI option isn't visible, check that you're in a text block (not an image block) and that your Klaviyo plan includes AI features
4. Review and Customize
- Read the generated copy — AI tends toward generic; add specific product names, prices, and any time-sensitive details
- Adjust CTA button text to match the offer
- Use Preview & Test to see how it looks on mobile
Real Example
Scenario: It's Tuesday. You need a Prime Day teaser email for your insulated water bottle line, going out to 3,000 past buyers on Thursday.
What you type: "Teaser email for Prime Day sale on insulated water bottles — dropping a mystery deal Thursday. Build anticipation, don't reveal the discount yet. Tone: playful and curious."
What you get: A 150-word email body with a curiosity-hook opening ("Something big is coming..."), 2-3 sentences teasing the deal, and a CTA button text suggestion like "Be the First to Know."
Tips
- The subject line generator works best when you give it the specific offer and audience — "20% off outdoor gear, targeting abandoned cart customers" beats "sale email"
- Always replace generic AI phrases like "Amazing deals await!" with specific product names and prices
- Generate 3-4 subject line variations and A/B test the top 2 — Klaviyo makes this one click
Tool interfaces change — if a button has moved, look for similar AI/magic/smart options in the same menu area.
