Email & Landing Page Builder

Reading time: 4 minutes


Since Mautic 3.3, Mautic has shipped with an updated, modern builder for creating emails and landing pages. It is available as a beta release - an optional plugin - until Mautic 4.0 where we plan to fully replace the legacy builder, assuming all goes well during the beta phase.

To use your existing templates with the new Email builder, you will need to add one line to your configuration file. Read on for further details.

About GrapesJS

The new builder is based on the Open Source GrapesJS framework and was created by the team at Webmecanik who have kindly donated it to the Mautic Community.

GrapesJS is an open-source, multi-purpose, Web Builder Framework which combines different tools and features with the goal to help build HTML templates without any knowledge of coding.

Available end-user features

Drag & Drop Built-in Blocks

GrapesJS comes with a set of built-in blocks, in this way you're able to build your templates faster. If the default set is not enough you can always add your own custom blocks.

Limitless styling

GrapesJS implements a simple and powerful Style Manager module which enables independent styling of any component inside the canvas. It's also possible to configure it to use any of the CSS properties.

Responsive design

GrapesJS gives you all the necessary tools you need to optimize your templates to look awesomely on any device. In this way you're able to provide various viewing experiences. In case more device options are required, you can easily add them to the editor.

The structure always under control

You can nest components as much as you can but when the structure begins to grow the Layer Manager comes very handy. It allows you to manage and rearrange your elements extremely fast, focusing always on the architecture of your structure.

The code is there when you need it

You don't have to care about the code, but it's always there, available for you. When the work is done you can grab and use it wherever you want. Developers could also implement their own storage interfaces to use inside the editor.

Asset Manager

With the Asset Manager is easier to organize your media files and it's enough to double click on the image to change it.

About the builder

Enabling the builder

Since Mautic 3.3-RC1 the builder is available to enable in the Plugins section of Mautic. Go to the Settings (click the cog wheel at the top right) > Plugins > GrapesJS and click on it. Change the slider to Yes.

Now you will need to clear your Mautic cache (located in var/cache) before you will be able to work with the new GrapesJS builder.


To use your existing templates with the new Email builder, you will need to add one line to your configuration file in the template folder:

"builder": ["grapesjsbuilder"],

If you wish to use the theme in multiple builders, you can use this syntax:

"builder": ["legacy", "grapesjsbuilder"],

NOTE: This syntax changed between Mautic 3.3.* and Mautic 4 to enable support for multiple builders - if you have been testing in the beta phase you will need to update your configuration files, otherwise you will experience a 500 error.

An example of a full configuration file can be found in the blank theme:

  "name": "Blank",
  "author": "Mautic team",
  "authorUrl": "",
  "builder": ["legacy", "grapesjsbuilder"],
  "features": ["page", "email", "form"]

From the 3.3 General Availability release there will be three email templates that support MJML, and also some landing page templates will also be made available in the near future.


If you search through the list of available themes, the new MJML themes Brienz, Paprika and Confirm Me will not be available until you enable the GrapesJS plugin.

Reporting bugs

Known bugs / issues

Please use the issue queue on the Github repository to check for the latest updates and report bugs with the plugin. Be sure to search first in case someone has already reported the bug!

Switching back to the legacy Builder

In case you are not happy with the plugin at the moment, you can easily switch back to the legacy Builder (original Mautic Builder). You can do so very quickly:

  1. Go to Mautic Settings > Click the cogwheel on the right-hand top corner
  2. Open the Plugins Directory > click on "Plugins" inside the menu
  3. Find the GrapesJs Plugin and click on it > Click "No" and then "Save and Close"
  4. Clear the cache

The GrapesJs Plugin has been unloaded, and the legacy builder will now be active again.
