1. Email Design System

Real brand control vs. defaults that anyone can override

Klaviyo has a Brand Library that sets defaults, but as users in Klaviyo's own community confirm, anyone can freely change colors, fonts, and layout. In Better Email, branding is structurally locked. Picking the wrong color is simply not an option.

Feature

Better Email

Klaviyo

One design system for all brands

Design system guide

All brands live in one Email Design System. Build an update once and it applies across the board automatically

Separate templates per brand, no shared design system governance

Locked brand elements

How locking works

Colors, spacing, and typography are structurally locked. Picking an off-brand color is not possible

Brand Library sets defaults, but anyone can freely override colors, fonts, and layout in the editor

Module reuse with live updates

Templates and modules

Master modules in the Email Design System. Changes propagate to every email using that module

Universal content blocks can be reused, but editing a block does not update existing emails

Editable content zones

Building templates

Precise control over what editors can change in each module. Everything else is locked

No granular control over what can be edited. Everything is open to everyone

Global brand update

Change your primary color in one place and every email in the design system updates automatically

Global style settings apply at creation time, but do not propagate to existing emails

Multiple brands from one account

Fully separate brand universes with their own design systems, all from one organisation

Klaviyo Portfolio (2025) links separate brand accounts under one login, but each brand still needs its own account and subscription

Liquid templating

Merge tags and Liquid

Lightweight, open source, AI-friendly. No certifications required

Klaviyo-specific Liquid dialect for personalisation and conditional blocks

"It seems you cannot restrict design choices in Klaviyo"

A direct quote from Klaviyo's own community forum. Every user can change colors, fonts, and layout freely, regardless of what Brand Library has set as defaults. Over time, that creates inconsistency.

2. AI

AI that builds the email for you

Klaviyo now has Composer for generating campaigns from prompts and Remix for AI image editing. Neither is tied to a locked design system. Betty knows your Email Design System. What she produces is always on-brand, not just approximately right.

Feature

Better Email

Klaviyo

AI that builds the whole email

Betty AI in the editor

Betty builds modules, content, and structure from a simple prompt, always inside your Email Design System

Composer (early access, April 2026) generates complete campaigns from a prompt, but without locked brand structure or design system logic

Generate from a URL

How Betty works

Betty visits the page, pulls the content, and builds a finished email with the right tone of voice

Not supported. Composer works from text prompts and file uploads, not URL scanning

Generate from a Word doc or PDF

Upload a document and Betty builds the email directly from the content

Composer supports file uploads as input for campaign generation

AI that knows your brand

Betty works inside your Email Design System. Output is always on-brand, not just brand-inspired

Composer uses your brand voice and rules, but cannot structurally enforce locked design elements like colors and typography

AI copywriting and subject lines

Betty writes and adjusts copy via chat, with full context of the email

AI assistant for subject lines, preheaders, and body copy

AI translation

Translation in Better Email

Betty translates to any language via chat and keeps structure and formatting intact

No native AI translation

AI image editing

Not included. Betty focuses on structure, content, and layout

Remix AI image editor: adjust product photos, swap backgrounds, and change colors directly in the editor via prompts

Chat-based editing

Tell Betty what you want to change and she does it directly in the editor

Composer supports multi-turn conversation for refining campaigns

< 2 minutes

Time to first draft with Betty AI

3. Collaboration and approvals

Approval flows without the bottlenecks

Klaviyo is built to send emails, not to collaborate on making them. Better Email gives the whole team one place to meet: designer, copywriter, marketing manager, and stakeholder, all in the same tool.

Feature

Better Email

Klaviyo

Real-time collaboration

Review and collaboration

The whole team works simultaneously in the same email

Not supported. One user at a time

Comments and feedback

How approvals work

Comments and approvals in one place, no long email threads

No native commenting

Structured approval workflow

Approval workflow

Feedback rounds with status tracking and sign-off directly in the platform

No native approval flow. Requires a third-party tool

Approvals without extra seats

Anyone can be invited to comment and approve. No login or payment required

Everyone who needs access requires a paid Klaviyo user seat

User roles and permissions

Roles and permissions

Admin, Designer, Editor, and Reviewer roles with granular control over what each person can do

Basic user roles, no control over what can be edited in templates

Preview links for stakeholders

Preview and testing

Share preview links with stakeholders, no login needed

Possible via send test. Requires an email client, not a browser preview

How Better Email and Klaviyo work together

4. E-commerce

Built for e-commerce teams that send a lot

E-commerce brands send a high volume of emails: product launches, sales, newsletters, flows. The more emails you send, the more likely your brand drifts. Better Email is how you stop that.

Klaviyo alone

Powerful automation and flows for e-commerce
Strong segmentation and personalisation
Brand drift over time. Anyone can change colors and fonts freely
No structured collaboration or approval process
Updating your footer means editing every template manually

Betty builds new campaigns in under 2 minutes
Update your footer once and every email updates automatically
One-click export to Klaviyo once the email is approved

5. Product feed integration

Dynamic product emails from your XML feed

Klaviyo can send emails with product data, but the design and image work is still manual. Better Email connects to your product feed, crops and enriches images with AI, and lets you build product modules with locked brand rules. Your editors cannot accidentally break the look.

Connect your XML feed

Paste the URL to your product feed (Shopify, WooCommerce, Magento, or any standard XML feed) and Better pulls all your products with images, prices, and titles automatically.

Build product modules with advanced settings

Pick products from the feed and create modules with dynamic fields. Set exactly which data editors can touch, and lock the rest, so your team works within your brand no matter what.

Crop and enrich product images with AI

Betty crops images to the right format automatically and adds brand splashes, badges, and overlays based on feed data like price, stock level, and category.

Export to Klaviyo

Once the email is approved, export to Klaviyo with one click. Product data, images, and dynamic content all go with it, ready to send.

AI image cropping

Betty crops product images to the right format automatically. No manual post-processing.

Dynamic splashes and badges

Add discount badges, "New" splashes, or other overlays automatically based on feed data.

Brand-locked product modules

Precise control over what editors can change in each product module. Everything else stays locked.
