There’s no avoiding email—as much as we might wish otherwise—but Spark makes tackling an unruly inbox a whole lot more pleasant. The app is an immediate joy to use, thanks to a painless setup process and a sharp, clean layout. But Spark’s true value comes from its clever interface, flexible customisation and the way it bubbles important emails to the top while filtering out the noise. Inbox intimidation is now a thing of the past.
Rarer than hen’s teeth

That’s my reviews. Something has to be really special for me to review it. Spark is that special app. In many years of using many many apps on the iOS platform this is the most mind blowing app I’ve ever seen. I keep wondering what’s happened to all my emails - what used to take a long time to process is now just a few clicks. I reckon I’m saving at least two hours a day now I’m using Spark. Not only that but it’s hugely intuitive, integrated with file systems and more powerful than anything else I’ve seen. Today I wanted to email two PDF invoices. I’d never done this with Spark before however in about ten seconds I had worked out how to do it and sent the email. It was that obvious and that simple. What could be better? Give me Spark for Mac and for Windows 10 (on a Surface Pro) so I can use it wherever I am. Spark is what iOS Mail always should have been. Great work guys.
One of the best email clients ever

This app has made managing large volumes of email easy. Combined with a good rules engine, like Gmail, it sorts stuff easily. Other reviews complain about stuff, because this works a bit different. Read the how to and FAQ if you get stuck and you'll be amazed at how quickly it corals your inbox. Power tip, edit the default settings to meet your needs, snooze and reminders don't have to be the defaults, and the ability to focus on one email account or see all is a breeze too when you need to focus.As to development, suggestions and updates are taken on board and flow through with regular updates. Well done Readdle, an excellent product!
Please bring to windows!

Over the past 6 months or so, I have tried multiple email clients trying to find anything as good as Spark. Nothing even comes close. Thank you for making such a great product. Please can you bring it to windows though!? My work computer has to be windows and the email clients are killing me! Love your work. I don’t review apps(EVER!), but you deserve it.
Gmail labels are available on iOS, making it easier to organize emails, store important information, and search your inbox.
Choose where labels appear across the app via Spark Settings > Appearance.
