Better Email vs. Knak

Both platforms solve the same problem: on-brand emails at scale, without bottlenecks. The difference is the approach. Knak is a no-code builder where marketers assemble emails from standard blocks inside brand guardrails. Better Email is built around a code-based Email Design System, where your team defines the modules, settings, and validations that become the editor marketers use.

Overview

Both platforms are built for enterprise teams that care about brand. The choice comes down to how much control you want over the foundation your team builds on.

1. Email Design System

A design system in code vs. brand settings in a builder

This is the core difference between the two platforms. Knak gives you brand guardrails: colors, fonts, and lockable modules configured through the builder UI. Better Email gives you an actual design system in code: developers write modules in HTML and Liquid, define every setting marketers get, and validations enforce the rest.

Feature
Better Email
Knak
Modules built in code (HTML + Liquid)
A real code editor with a Liquid linter. Full control over the markup that ships
Modules are assembled in the drag-and-drop builder. The HTML block is disabled by default
Custom settings per module

Elements can be set to editable, locked, or hidden. There are no custom inputs

Dynamic content covers audience variations, not templating logic
Global Script and shared inputs

You design the editor experience
What marketers can edit is exactly what your design system exposes. Nothing more

2. Editor

Email builder and editor

Marketers get a no-code, drag-and-drop experience in both platforms. The difference is where that experience comes from. In Knak, everyone works with the same standard blocks. In Better Email, the editor is generated from your design system, so every option marketers see is one your team designed.

Feature

Landing pages
Better Email is focused on email
Same builder, with lead data passed to your marketing platform

An editor your team designed

Because the editor is generated from your Email Design System:

  • Every input marketers see is one your team chose to expose
  • Validations block off-brand content while people work
  • Content zones control which modules can go where
  • Publish a new module once and every campaign builder gets it

Full rendering control

Because your Email Design System is real HTML you control:

  • Guaranteed correct rendering across all email clients
  • Rounded buttons that actually work in Outlook
  • Custom layouts that standard content blocks can't express
3. Collaboration

Collaboration and approval flows

Both platforms take review seriously. Knak offers pinned comments, review groups, and staged approvals. Better Email works the same way on the surface and goes further underneath: approvals are tied to a specific revision, and one org setting stops any campaign from reaching your ESP before it is approved.

Feature
Better Email
Knak
Pinned comments on the design
Pins anchored to modules, threaded replies, resolve and reopen
Click to drop a pin, with feedback in the sidebar
@mentions and notifications

Required and optional approvers with automatic reminders
Review groups with sequential approval stages
Approvals tied to a specific revision
Edit after approval and the approval goes stale. Sign-off means sign-off on what ships

4. AI

Betty vs. KnakAI

Both platforms have invested seriously in AI. KnakAI generates on-brand, editable emails and landing pages from a brief. Betty goes further in both directions: she builds campaigns from your approved modules in the Campaign Builder, and co-authors module code with your developers in the design system editor.

5. Integrations

Integrations and sync

Neither Better Email nor Knak sends emails. Both connect to the platform that does. Knak covers a broad list of enterprise marketing platforms, with Marketo and Eloqua as its home turf. Better Email focuses on one-click export in your ESP's native personalization syntax, and builds custom connectors on request.

Neither platform sends emails

Better Email and Knak both focus on creation. Your ESP or marketing automation platform handles sending, whether that is Salesforce Marketing Cloud, Braze, Klaviyo, HubSpot, or something else.

Who is each platform for?

Both solve on-brand email production at scale. The choice comes down to how much control you want over the foundation.

Better Email is for you if...

  • You want your design system in code: HTML and Liquid your team fully controls
  • You want to design the editor experience with custom modules, settings, and validations
  • Brand control should be structural, not just permission-based

  • You need export in your ESP's native personalization syntax, or a custom connector
  • You manage multiple brands or organisations with separate design systems

Knak is for you if...

  • You want a 100% no-code workflow with no developer involvement at any level
  • You need landing pages in the same platform as your emails
  • Standard content blocks with lock-based guardrails cover the designs you need
  • You want admins to configure modules and guardrails visually, without code
