Email template builder and editor

Klaviyo’s editor features an intuitive drag-and-drop interface that makes email design as simple as stacking blocks. You can easily add and arrange content elements—text boxes, product images, call-to-action buttons, dividers, etc.—to craft engaging layouts, all without touching a single line of HTML​.

This simplified design process means anyone on your team can build a great-looking email in minutes. The editor is built for speed: it’s easy to experiment with different layouts or quickly tweak content on the fly. Even advanced elements like dynamic content blocks or conditional sections are straightforward to implement with simple show/hide logic (so a single template can display different content to different segments).

– Easily arrange blocks like text, images, and CTAs—no code needed.

– Choose from dozens of pre-designed layouts to get started quickly.

– Rearrange, edit, and preview designs with a simple click-and-drag interface.

Maintaining a consistent brand look and feel across all your emails is effortless with Klaviyo’s builder. The platform supports universal content—meaning you can save custom-designed blocks or sections (like headers, footers, product showcases, or social icons) and reuse them in future emails​. From here, you have one of two options:

1. Update a saved block once, and it can automatically update everywhere it’s used, ensuring every campaign stays on-brand without repetitive work.

2. Unlink the block and section, and edit independently if you’d like your edits to only apply to the template you’re currently editing.

You can also define global styles for fonts, colours, and logos to enforce brand guidelines universally. This way, every email your team sends has a cohesive, professional appearance. No more hunting down and fixing an off-brand font or outdated logo in 20 different templates—the builder handles consistency for you, saving time and safeguarding your brand identity.

– Universal content blocks: Save time by creating reusable headers, footers, blocks and sections.

– Global style settings: Lock in fonts, colours, and logos across templates.

– Show/hide logic: Customise content visibility based on customer segments.

Whether you prefer to start from scratch or from a proven design, Klaviyo has you covered. The email library comes with 160+ customisable email templates created by professionals, offering a powerful starting point for creating stunning emails for any campaign​.

You can browse templates tailored to various industries and use cases (seasonal promotions, newsletters, announcements, and more), then easily tweak the layout and content to fit your needs.

For those who have a specific vision or existing code, Klaviyo’s builder also supports a hybrid template approach—you can combine custom HTML with the drag-and-drop tools in the same email​. This means your team has full creative control: designers and developers can craft custom sections with code, while marketers can still edit text and images through the visual editor.

It’s the best of both worlds—use a beautiful pre-built template, a completely custom design, or any mix of the two. In all cases, the builder ensures the final email is responsive and polished.

– Start from 160+ customisable templates designed for ecommerce and B2C use cases.

– Use custom HTML for more advanced styling and interactivity.

– Combine HTML with drag-and-drop editing in hybrid templates.

Writing compelling email copy and subject lines can be a challenge, even for seasoned marketers. Klaviyo’s email editor includes built-in AI tools, including brand voice guidelines, to help accelerate the content creation process. With a click, you can generate on-brand email text or get suggestions for improving your copy—great for when you need inspiration or have writer’s block.

The editor’s subject line assistant, meanwhile, can propose attention-grabbing subject lines tailored to your campaign, helping you boost open rates. These AI features work in the background to save you time and refine your content, so you can create effective emails faster. The result is an email that not only looks good, but also has messaging that resonates with your audience—all with far less manual effort.

Every email built in Klaviyo’s template editor is automatically responsive and optimised for mobile devices​. The builder ensures your content adapts to different screen sizes and email clients without you having to do extra work. You can trust that your subscribers will have a smooth experience whether they open your email on a phone, tablet, or desktop.

To double-check and fine-tune designs, Klaviyo provides robust preview functionality: you can preview how your email will appear on desktop or mobile devices, and even preview the email as if you were a specific customer (using profile data) to see personalised content in context. By catching any formatting issues before sending, you’ll ensure pixel-perfect emails and eliminate unpleasant surprises—no more worrying that a button might look misaligned on iPhone vs. Android, for example. Optimising for mobile has never been easier, and it’s built into your flow.

– Know every email is automatically mobile-friendly.

– Preview designs on different desktop or mobile screen sizes before hitting send.

– Optimise content layout for small screens without extra work.

Perhaps one of the biggest advantages of Klaviyo’s email template builder is how it saves time and reduces the need for engineering or design resources. Because the editor is so intuitive and full-featured, your marketing team can handle end-to-end email creation independently.

Need to spin up a last-minute campaign? You can do it in-house without submitting a request to the dev team. Want to refresh your newsletter design? Drag, drop, and style it yourself instead of waiting on a graphic designer.

By eliminating these bottlenecks, Klaviyo lets you respond to opportunities faster and send more campaigns that drive revenue. Teams work more efficiently and can focus on strategy and content rather than fiddling with code.

– Build and launch without needing developer support.

– Reduce internal handoffs and delays for last-minute campaigns.

– Empower teams to launch faster, test more often, and learn quickly.
