Spark is a great email solution if you want to move past your default Mail app on iPhone, iPad, or Mac. It offers a host of helpful features and one of them is the Smart Inbox.
The Smart Inbox is a spot in the app that gathers emails from your various accounts and categorizes them for you. This gives you a fast and easy way to zip through your inbox. The key is configuring it to work for you and here’s ways you can do that.

Most iOS users utilize the Mail app on their device by default for any email-related activities because it's the stock app for doing so. Unfortunately, after deleting the Mail app (post-iOS 10), iOS won’t redirect mail:to links to your favorite third-party email app when you tap on them.
MailClientDefault10 is a new jailbreak tweak release by HiDan that fixes this problem by letting you configure a third-party email client as the default app for composing emails, which effectively solves the aforementioned problem.
