Best software-generated email HTML on Earth

Manual email coding made obsolete

We have spent years improving our email code generator algorithm to perfection. Now it's available to you, to create and send as high-quality email HTML as possible without coding.

Email code that compatible with all major email clients.

The secret of high-quality

email HTML

Email code is regularly tested with both Litmus, Email On Acid, and our own email client rendering tests.

Outlook friendly backgrounds

Turn VML background images on/off
Improved accessibility

Turn 'role=presentation' on/off
Gmail Promotions-tab annotations

Design and edit on the front-end
Fully-clickable high-converting buttons

Boost CTR% with bulletproof CTA buttons
Templating languages for dynamic content

Drag-n-drop Handlebars, Liquid, Mustache editor

A client asked for background optimization for Outlook. We spent 6 hours adding custom VML. If we had been able to use Chamaileon on the project, we would have sorted this out with the flip of a switch.

Marketers enabled to create stunning emails campaigns on their own.

Comparing top email builder's code output for size and rendering quality

We replicated the same email with the top email builders to see the code and rendering difference.

We compared the HTML code size (that matters!) and the rendering quality as well. The original email design was created by using MJML email code language.

MJML (original template)

Email HTML Size 60 Kb (+33.3% compared to Chamaileon)

Pros:

Background image support in Outlooks (VML backgrounds)
Ideal for tech-savvy developers who don’t want to learn email coding tricks but familiar with building in code

Cons:

MJML is only an open-source email templating language paired with an HTML generator
No visual editor interface is available
It doesn’t offer any user handling, email, team, asset management, or anything similar that email creation platforms do
No support.

Original email created with MJML framework

Chamaileon

Email HTML Size 45 Kb (-25% compared to original)

Pros:

Background image support in Outlooks (VML backgrounds)
Real-time collaboration with team members
Pixel-level control over every design property including margins
Visual email design editor with configurable email HTML generator

Cons:

Flexible but complex editor interface (ideal for marketer/designer who has some experience with drag-n-drop content building)
Mobile paddings can be controlled on multi-column elements only, other responsivity-related adjustments require the user to take advantage of the “Show on mobile” settings.

Flawless html rendering match with Chamaileon

BeePro

Email HTML Size 77 Kb (+28% compared to original, +71% vs Chamaileon)

Pros:

Simple editor interface (ideal for beginners)
Real-time collaboration with team members
Ability to create landing pages with the same editor

Cons:

Background images don’t work in Outlook email clients at all
No control over the margin property at all
Can only change padding in 5 px increments
Can’t adjust line-height by pixel (4 built-in line-height options)
Can’t resize images precisely (px) but only as percentage
Can only add margin/padding to columns one by one
Can’t scroll screen while dragging an element

Stripo

Email HTML Size 50 Kb (-16% compared to original, +11.1% vs Chamaileon)

Pros:

Could replicate the original design with ~90% match
Control over mobile paddings (although changes are not visible in the editor)
Partly allows HTML code editing (but works with Stripo-specific email HTML)

Cons:

Background images don’t work in Outlook email clients at all
No control over the margin property
Can only change padding in 5 px increments
More complex editor interface (ideal for marketers/designers who have some experience with email builders)
Can only change image size in 5 px increments
Transparent row background doesn’t work
Only 4 line-height options are built-in (can’t adjust line height by pixel)

Developer-centric editing experience with Stripo

Unlayer

Email HTML Size 60 Kb (+33.3% compared to Chamaileon) but much simpler design

Pros:

Pixel level control over padding sizes
Line height can be adjusted in 10% increments

Cons:

Couldn’t match the original design at all
Doesn’t support background images in the content at all (only row background is available)
Can’t customize column widths at all, either spacing between them
No control over margin property
Can only change image size in 5 px increments
Default padding needs to be removed many times
Way too many rendering issues in several Outlook versions

Design flaws and large code base with Unlayer

Dyspatch - No option to build an email design!

Email HTML Size 102 Kb (+217% compared to Chamaileon)

Based on our initial tests Dyspatch is clearly not an email builder or design solution since it’s impossible to create a custom email design.
For the test, we rebuilt Dyspatch’s newsletter that arrived as a clipped message and was sent on 09.29.2021.
Rebuilt the email in Chamaileon with a 100% rendering match and the Chamaileon version was only 46 Kb. It took 45 minutes to rebuild the exact same email from scratch but it can be imported to Chamaileon as a template in under 5 minutes.

Dyspatch is not a real email builder tool

Optimize the email creation workflow without compromising quality.

Email creation platform

Import your email HTML to generate a template or build your email from scratch.
Team-oriented asset management solution

Let your employees and clients access email templates without breaking them. Control who can edit what and centralize the review and approval workflow.
Real-time collaborative tool

Build email templates together with your team simultaneously and see changes being made in real-time, just like you would in Google docs!

Weeks spent with email creation. Reduced to hours.

We have met the brightest brand and agency email marketing teams. Suffering from eye-wateringly painful production processes (even if they had the tools). Chamaileon's Agile Email approach helped them write, design and build at the same time and love working on emails.
