How to use AI to write better Klaviyo emails

Why this matters right now

LLMs are everywhere, and yes, they can absolutely help you write better Klaviyo emails. But most brands either overuse AI until every email sounds like ChatGPT, or they ignore AI entirely because they “don’t want to lose the human touch”.

The reality is this:
AI is not here to replace your marketer. It’s here to replace the blank page.
Brands that have learned to combine human strategy with AI execution are already sending sharper emails, faster, and with significantly more consistency.

If you’re a mid-market eCommerce brand doing 2M to 25M a year, this is an advantage you cannot ignore.

What this actually is

This is not about letting AI write your emails.
This is about using AI as a strategic partner that improves:

• message clarity

• angle variation

• segmentation logic

• subject line testing

• speed of production

• consistency of tone

Think of AI as your junior copywriter who works fast, never sleeps, and needs good direction. It’s your job to guide; it’s the AI’s job to execute.

Who this is for

This approach works best for brands that:

• Are sending frequent email campaigns (at least weekly)

• Have foundational Klaviyo flows in place, but want them sharper

• Have an established tone of voice

• Need scale without sacrificing quality

• Want their marketing team working faster, not just harder

If you’re running a high-growth Shopify or Shopify Plus brand in fashion, jewellery, skincare, home, or lifestyle – this is built for you.

How to use AI to write better Klaviyo emails

1. Start with a structured prompt

AI output is only as good as your input.
Give it context, brand rules, audience nuance and the purpose of the email.

Example prompt:

“You are writing for a premium New Zealand skincare brand. Tone is warm, expert and conversational. Audience is women 28–45 who value results and ingredients. Write a campaign email promoting our new vitamin C serum. Avoid over-claims. Use short paragraphs. Prioritise clarity over cleverness.”

This alone eliminates 80 percent of robotic-sounding output.

2. Use AI for angle ideation, not final copy

Let it generate:

• email angles

• headlines

• CTAs

• product benefit variations

Pick the best parts and weave them into your human-crafted final version.

It’s like running a brainstorm in 10 seconds.

3. Keep the human edit as a non-negotiable

Your brand voice, point of view and micro-nuances cannot be outsourced.

AI will get you 70 percent there in minutes.
Your job is the last mile.

That’s where tone, intuition, and brand-specific magic live.

4. Use AI inside your segmentation logic

Most marketers underuse LLMs for data interpretation.
Feed in engagement segments or customer behaviour patterns and ask it:

• why certain groups aren’t converting

• how messaging should shift by RFM segment

• what emotional triggers matter for “At Risk” vs “Champions”

• what objections a specific cohort might have

This is where email revenue jumps significantly.

5. Don’t let AI write like AI

The quickest fixes to de-robot the output:

• shorten sentences

• remove filler words

• cut clichés

• add specificity

• reference real product details

• weave in brand quirks or cultural references

Every line should pass the “would a real person say this?” test.
