Spark gives time back to all those who live by their inbox by helping to quickly see what is important and clean up the rest. Features Smart Inbox intelligently bubbles what matters to the top and lets you quickly see what's important in your inbox and clean up the rest. All new emails are smartly categorized into Personal, Notifications and Newsletters. Powerful, natural language search makes it easy to find that email you're looking for. Just search the way you think and let Spark do the rest. Smart Notifications filter out the noise, letting you know when an email is important, saving you from notification overload. Your calendar invites have their own, beautiful card with one-tap accept. See if you want to accept it right from your email. Before you send an email, quickly swipe to choose the right signature for the occasion. Quick Replies get the point across with just a tap. Love, like or acknowledge an email in an instant. That terrible "forward" and quote mess in your inbox is now replaced it with a beautiful, threaded message design. Snooze an email and get back to it when the time is right. Snoozing works across all your Apple devices. Integrate Spark into your workflow and take productivity to the next level. Supports Dropbox, Box, iCloud Drive, Evernote and more. Customize Spark to work as you do. You decide which swipes do what, what cards are shown, and how many emails you want to see. Teach Spark about that newsletter you just can't miss, and you'll get a notification every time it arrives. Spark learns as you email.
