Edit the HTML of a building block
While editing a campaign, select the block on the EasyEditor canvas and then select HTML in the text toolbar – this opens the HTML editor in a side panel.
Not all email clients interpret HTML in the same way, so be careful when editing that you're using appropriate markup.After editing, select APPLY to confirm your changes or CANCEL to exit without confirming.
