Conditions
The conditions tab is the second one when you want to create an automation or edit one. The conditions comes just after the automation is triggered, if you set conditions to your automation, they will need to be verified for the automation to be executed.
As you can see the 3 other tabs are still blocked, if you don't want to set any conditions you'll have to click on one of the save button, this way you can access to the other steps.
This step will change according to the triggers you've set earlier, if you choose a classic trigger, you can execute condition just on all AcyMailing users, otherwise if you chose a trigger based on user action, you can execute condition on the user who trigger the automation or all the user.
