New to Spark, but…..


I use several email clients due to work, my own business, personal, etc. To say I despise the Gmail format is an understatement, so I was looking for something relatively user friendly, streamlined, and fast to manage, as I have planned to incorporate all these emails into one client by “forwarding.” I am trying Spark after using Outlook for yeasrs. I like a lot of the customization of Spark, but where it shines for me is the ability to customize the “swipe” feature. I can move emails around immediately without going to the ribbon IF I customize it to suit my own needs.

Yes, you have to take some time to learn the mechanics of it, and yes you have to customize it, and YES it’s a learning curve (albeit not a steep one). I’ve had it for less than two weeks and the only bit I don’t use yet is where I might connect it to a “note” app. For me, I would have liked to see a “Notes” feature inside Sperk to activate shoudl I choose instead of using one of these other programs, but I get that this would work for many folks…..I’m not one of them, though, as my notes are really quick and short (think stickies more than notebook notes).

That said, it’s not a heavy user program, IMO. It’s for those of us with short message needs and to keep our heads above water with all our clients. In that, I think it’ll be a keeper. (and let’s face it….ANYTHING is better than the Mac’s mail app—or at least I think so).

Really good client, still waiting on some features


Overall, Spark is excellent. Organization of emails and the Smart Inbox are incredible. The search is more powerful than any other client I’ve used. It has swipe customization and the smart inbox groupings make it easy to archive a pile of emails in a second.

There are a few things I’m still waiting on though. One is the actual mail pane. This is where Spark actually loses functionality rather than simply leaving out some luxuries. It needs some work. Scrolling and zooming are rather buggy. With Spark, I don’t need to open half of my emails, but the ones I do are rather difficult to work with at times, especially on my smaller laptop screen where I don’t want to expand the pane.

The other features are all regarding continuity. Spark for iOS is pretty great too, but the apps are inconsistent with eachother. Search history isn’t synced between apps and the iOS version doesn’t have a “recently seen” tab at all, so I defintely can’t quickly bring up an email that I just saw and archived from my phone. The appearence is also pretty different. Seeing the two apps work together a bit more would be excellent.

Great email app with tremendous custommer support team


I’m a Mac user that needs to have an email app that works on all Apple platforms. I’ve used nearly all the major ones, including Airmail—which I stopped using after it stopped rendering email content from several sources, including the Washington Post and others. I repeatedly brought it to their attention and they couldn’t fix it. I have been using Spark for Mac/iPhone/iPad for several months now and fiund it to be a truly outstanding product. It is nearly perfect but could use a few more functions, like being able to copy an email to a folder rather than move it, or having a range of notification sounds rather than two. What impresses me the most is their awesome support team. I recently had a problem with snoozed emails coming back to the Inbox before their time. I emailed their support team and they worked on the issued diligently and came up with a fix, all the while keeping me informed. They are a class act, whioch is why I buy Readdle products. As long as they keep paying attention to customers I’ll stick with them.
