We've already explained how to set up Zapier rules to help you automate your Campaign Management. But Zapier has a more advanced setup that you can use to further the complexity of your rules: Filters!
When you're creating your Zap, you'll see a step between the two apps you're linking (the "+" button circled in red below):
Clicking on the + will add a new step, and will enable you to decide whether or not the action you asked the Zap to perform should be done or not:
After that, the extent of your filter will depend on the App you had chosen first; In our example of the weather, we can select different metrics such as humidity, wind speed, cloud cover and decide that the trigger should only be fired when the general condition and the filter condition are met.
With these filters, you should up your automation game!
