How to add countdown timers in Campaign Monitor campaigns?

You can create a letter in the Campaign monitor using the Drag & Drop editor or from a template, and the system allows you to save your own drafts based on HTML. Ready messages are adapted to be displayed on any device, include a block of social network buttons and the option to integrate a video player. Unfortunately, the letter editor does not have a function for conveniently editing the html template, so we will not be adding the HTML code in a standard way.
