How do I create a dynamic content block based on interests?

You create a dynamic block based on interests in two steps:

Tick the white checkbox next to the title of the content block. Change the block type from Standard block to Optional block.

You now see a red dot on the right side of the content block. Click on the red dot and choose the right area of interest.

Only recipients with this specific area of interest will see this content block. This option is only available for Marcom Campaigns or eCom Enterprise.
