The first thing you need to do when designing your own automation workflow is to determine the type of trigger that will set your automation in motion. There are various types of triggers available - the "When some people don't click my campaigns" trigger will get your automation fired up when some people don't click on a campaign. Please note that the automation will be triggered only for regular campaigns and not for "Automation" campaigns.
There are two parameters that you need to define on this type of trigger:
1. You need to define the time that the workflow will wait before checking for people that haven't clicked on a campaign.
2. The second parameter has you choose between days/months/years, as a measure of time for the number you typed.
Note that you may notice a short delay added to the time you selected above. After you are done, just click on the Save button to have your trigger ready and waiting inside your workflow.
This is the starting point for creating a workflow that will be triggered whenever some people don't click on your campaigns. Learning how the available Conditional / Control steps and the available Actions work, will help you finalize your design.
