Content Blocks are the building blocks of your notifications in Courier. They are reusable, drag-and-drop components that allow you to build notification content across multiple channels. Key features include:

​
Type of Content Blocks

  • Text Blocks
  • Image Blocks
  • Action Blocks
  • Divider Blocks
  • Markdown Blocks
  • Quote Blocks
  • Template Blocks
  • List Blocks
  • Jsonnet Blocks
Some blocks, like Text and Action Blocks, have channel-specific options or formatting. For example, you can set the color of a text block differently for email and SMS.
