When you start designing your own automation workflow, the use of tags inside your email list can prove to be very helpful to organize it as you see fit. One of the many available trigger types is the "When any tag is removed", which reacts by setting your automation in motion when you choose to remove a tag from the members of your email list.
There are two parameters required in order to set this type of trigger:
1. First, you should define the name of the email list, from which when any tag is removed, your automation will get triggered. You can find the available email lists on the drop-down menu; keep in mind that only tags removed from this specific list will trigger the workflow - the rest will be ignored.
2. The second parameter for you to complete is to choose whether the automation will be triggered for every removal of a tag, or whether it will be triggered only on the first tag removal.
After you are done, click on the Save button to have your trigger ready and waiting inside your workflow.
This is the starting point for creating an automation workflow that will be triggered whenever a tag is removed from the members of a specific list. Learning how the available Conditional / Control steps and the available Actions work, will help you finalize your design.
