What is an AI email builder?
An AI email builder drafts the whole email (structure, copy, and imagery) based on what you want the campaign to do. You describe the goal, and a draft comes back for you to edit.
You'll typically find that AI email builders fit into one of two categories. On one end is a drag-and-drop editor with a few smart fields bolted on: it can write a clean paragraph, but it has no idea what a segment bought last week or which shoppers are close to churning. On the other end is a builder grounded in customer data, where the draft arrives already shaped by who it's going to. The difference shows up in relevance, and relevance is what gets opened.
Why an AI email builder matters
The campaign calendar fills up faster than you can build. Every email needs layout, copy, a QA pass, and a personalization check before it ships. Multiply that across a week of sends, and the production work alone eats your strategy time. Meanwhile each marketer builds a little differently, so the holiday email looks nothing like the one before it, and the brand pays for the drift.
A few of the benefits of building with AI:
- Reviewing beats assembling: Reacting to a complete draft is faster than constructing one, even when the draft needs work.
- Consistency by default: Every draft starts from the same brand rules, so each send looks like it came from the same brand.
- One email, many audiences: Personalization comes from data instead of cloning a dozen near-identical versions by hand.
Why choose Klaviyo as your AI email builder
Klaviyo is the autonomous B2C CRM, so the builder isn't a copy generator bolted onto your email tool. Drafting, editing, and personalization all run on the same real-time customer profile that holds every shopper's browsing, orders, and predictive signals.
A campaign draft from a single prompt
Tell Composer, Klaviyo's marketing agent, what the campaign is for, and it returns an on-brand draft, for a one-time send or the emails inside an automated flow. A launch announcement and a welcome sequence start from the same kind of prompt, so the calendar stops depending on who has time to build.
An editor built for the refining half
The draft lands in Klaviyo Email, where a drag-and-drop editor, universal content blocks, and 160+ customizable templates handle the edits. Change a section once in a universal block and it updates in every email that uses it.
Personalization pulled from the live profile
Every profile carries browsing behavior, order history, and predictive signals like likelihood to purchase, and the email reads from it directly: a win-back that names the product a lapsed customer actually bought, a recommendation block stocked with what their segment buys, content that shows or hides depending on who's opening.

- Describe the campaign. Give Composer the goal (a product launch, a win-back, a seasonal push), and review the draft it returns.
- Refine in the editor. Adjust layout and copy with drag-and-drop blocks instead of rebuilding from scratch.
- Layer in personalization. Add recommendation blocks and show/hide logic so each segment sees content that fits.
- Approve, then extend to text. Sign off on the send, and pair it with a text follow-up for the subscribers who don't open.
