What are Custom Blocks?

This ensures brand consistency and saves significant time in the campaign creation process.

Custom block creation

Access the "Custom Blocks" tab within the Channel section to craft your custom blocks. Then, click on the "Create" button to initiate the process.

With the help of intuitive drag-and-drop functionality, tailor your block to perfection.

Setting tab

Provide a detailed description and specific information for your custom block.

You can also enable "content editable", which allows users to change the text of the element used (e.g. rename button, change welcome message). If it's turned off, users won't be able to change the text, but the settings with used attributes will still be editable (e.g., changing color, string, size, etc.).

Input tab

In the Input tab, define primary attributes that can be applied to various custom blocks within your CDP. Easily customize attributes by choosing from a variety of types, such as Pixel, String, Number, Enum, Color, and Image.

Provide clear labels, key values, and detailed descriptions for each attribute, enhancing clarity and usability. Add specific settings to attributes, such as selecting primary colors or uploading images, to suit your unique requirements.

Utilizing Attributes

Once configured, seamlessly reference these attributes in the Visual editor of this or any other Custom Block using the syntax $var(key-value). For instance, reference the primary color attribute as $var(primary-color), eliminating the hassle of manually selecting colors from the palette.

Save a custom block to make it usable in the email campaigns.
