We prepared custom blocks for the Email builder. The blocks that are currently available are:

Columns – Columns in different layouts
Text – Text content
Heading – Add heading
Image – Image from your media library
Divider – Divider to separate your content
Info box – Block that combines Heading, Description, Button and Image
WooCommerce Hook – Select one of the default WooCommerce hooks. This is useful for compatibility with plugins that add content to WooCommerce emails

There are many custom settings available for every block. That includes colors, font sizes, background colors etc.

For every block you can set the conditions for when to render the block – that means for example, that you can select you want to display specific text only if the order is paid with Bank transfer payment method.
