Really slick email
There's a reason this is a 5 star app there's more to this app than initially meets the eye. Once I went under the hood, that's when I started taking advantage of what this email app offers in comparison to other email apps. It's smooth, easy to use right after download and gives me so many different options like being able to snooze and set reminders, easily move emails around and because I might hand my phone to someone so they can look at photos, medical ID or other info, I'm able to lock this email and open it using face ID. I can go through spam, tap on spam emails I need but don't really want in my contacts and mark them as "not spam" so they go to a different folder. This makes emptying spam much easier and more efficient. Tapping on the red trashcan icon deletes spam quickly. There are ways of retrieving accidentally deleted emails. This really is the best email app I've used and it's ideal for work. When I finally convince a co-worker to give Spark a try, inevitably, they love it. In the past, I'd download an email app and inevitably go back to the iOS/Mac native apps because it's familiar m and there's no learning curve but I found this app to be easy to navigate from day one. When I started taking advantage of all this app offers, I found out that it really is "smart" email that learns my preferences over time. There's plenty of information and instructions within the app to use it to its full potential. My only regret is that I didn't start using it long ago.

One of the best free apps ! Room for improvement
I’ve used this app for over a year and I don’t have words to express how grateful I am to have found Spark. I’d talk about every nice feature and how this app has made my e-mail experience a lot easier, but I will only mention that it’s just very simple to use and has a great design. The ability to sync every account (gmail, college mail) you may have is not new but it works perfect. I really recommend giving it a try if you haven’t already. If the creators of the app are reading this, there are a couple of things I’d like: 1. We should be able to manipulate how certain emails are categorised (notifications, newsletter). 2. It’d amazing if we could have “rules”, so every time we recieve an email from an specific person or company, it’s automatically sent to archive or spam. 3. I’d love to have different design options. The ability to not only change the basic color but also the layout or different fonts and more (personally, I like minimal desings and I think Spark has the potential to reach that). I know that as a free app it may be difficult and I don’t know if you’ve thought about it but it’d be an interesting idea if there was a paid account to have those additional features that I mentioned and other REALLY important ones. If it was the case, I’d be willing to pay as long as you don’t create constant pop ups about it. Apart from that, I keep recommending this app to my friends and I still think this is one of the best apps despite being free ! 🙌🏼

Want to love it but….
I really, and I mean REALLY want to love this app. On the surface it’s everything you could want in an email client. Lately however, problems have crept in making it annoying to use, particularly between devices, where if I delete or arrange messages into relevant folders, it’s all cleaned up on one device, but when i switch to say… my phone… all the messages are still there in the inbox. It isn’t until I kill the app and do a pulldown refresh that the state of the inbox is actually refreshed. On top of that, on any given device at any given time, I’ll check my mail, clean out my inbox and flick the app away, only to discover the red dot with my message count hasn’t updated and it looks like I still have unread messages. To be fair this could just be an issue in ios, but I don’t have this issue with other apps so I dunno. Today, and what prompted me to finally leave a cautionary review - I actually had to delete and reinstall spark on my ipad to get it to realize i had already read and filed my messages on my phone. Minor annoyances to be sure, but as Readdle continues on their corporate path of “we can always make it better” - you’re breaking too much. Change is bad, ok. we spend years building email habits and expectations, and believe me, rocking a comfortable boat with more going on under the hood than you can keep working reliably is not the way. NOT THE WAY.
