Just like smart mailboxes in the Mail app, you can set up smart folders in the Spark email app. This makes organizing your inbox easier, plus gives you a specific spot to go to for those particular emails you need.
You can use smart folders in Spark for travel arrangements, purchase receipts, or work-related emails. Or, you can set them up for emails you received in certain time frame, with a particular type of attachment, or from a specific sender.
Whatever you might find smart folders useful for in Spark, here’s how to create and edit them on iPhone, iPad, and Mac.
