Just started using this. IT'S REAL GOOD 💯. I love the ability to archive multiple emails with 1 click. So far it's been doing a good job of only notifying me about emails that actually matter.

Mind blowing companies don't design for this first... Spark doesn't support email aliases, yet alias mailboxes may be set up as separate accounts via Add more accounts on the sidebar. This way you can compose emails and select the necessary account in From field.

Love the UI!

This just instantly replaced Mailbox in my iPhone's dock. It's fantastic.

Was great to get involved with the copy for Spark and the launch. You've done a great job with a new approach to email on iPhone and Apple Watch. Good luck with the launch, guys!

Very nice, it has everything I need but lacks support for html signature :/

Been beta testing it for some time. Very solid email client. The watch app is *the* reason i am sticking to it. really well thought

Switching to Android: is there a phone+desktop email client or workflow as smooth as Spark on iOS+Mac? Gmail Inbox is not even close 😔

Awesome team => Awesome products!! Great job guys.

Hello guys! Thank you for warm words and support. We'be been working on this for the last 18 months. I hope Spark will be on your home screen. Also, please note that this is just version 1.0 and we have a long list of things to add and improve. Mac + iPad are also coming a bit later.

Fantastic and even better now it has iPad support, just need the Mac version to complete the family

Installing now. Quick question, how do you guys make money on it if I don't have to buy it?

Excellent! Really been looking forward to this coming out. Looks great. Can't wait to ditch Apple Mail!

Made the switch from Mailbox to Spark (RIP Mailbox) and I have to be honest - I wish I would've switched a long time ago. Love how much I can customize the interactions with this app. Nice clean interface, intuitive experience and the ability to make it mine with all of these customizations! Love it, looking forward to the OS X version!

Great find! Most email apps claim to "revolutionize" email and end providing nothing but slightly modified UX at best. This one doesn't even claim that but actually does offer significantly improved functionality and a unique approach. It's been crashing a bit but I assume that's just the result of a few bugs that need to be worked out.

Looks great. I really like how it 'looks' but have some gripes with some of the quick reply functions. It would be great to have those NOT cut off the email trail. Also if you could customize the quick reply message options, that could be a huge time saver. The biggest adjustment for me will be to not have the Mail app's VIP function. I filter out messages from everyone except a few key VIP people to which I receive notifications from. The Readdle way would 'choose' these people for me, whereas I'd prefer to control who they are myself, selectively. I already have redundant notifications coming in from *that one email happy person* All that said, I haven't deleted it and look forward to the Mac app and this app's growth.

Anyone else having issues with dual display setup, where dragging a message to another window gets wonky and stretches almost infinitely but never actually moves to the second screen?

I was a beta tester for this app. It is without a doubt the best email client I've ever used on my iPhone. Kudos to the Readdle team for the work they did in putting this out. Their hard work is definitely evident.

This looks fantastic. Definitely going to give this a go.

Spark is a new email app from the team at Readdle. I know a ton of work went into this. Looking forward to checking it out. Here's an in-depth review true to @viticci's style via MacStories - http://www.macstories.net/review...
