With conditions, you can react to different event results.
Example: You have started a query and provided two answer options - A and B. Depending on what the user clicked, they get the corresponding tag and are directed to a separate sequence matching their answer (see image).
Example 2: Certain sequences may only start when a contact has (or does not have) a certain tag.
Conditions can only be configured if they are already connected to a following element!
Note: Name the following elements before you set the condition to give you a better overview.
A good example of how to design a query with Quentn and use conditions can be found in the video shown above.
