In addition to Google+ closing down, another Google product loved by many has also been shuttered: Inbox by Gmail. I loved using it when it came out. It sorted e-mails intelligently, allowed me to manage my e-mails easily, and looked really nice. For a few years, Inbox and Gmail were competing apps despite being made by the same company. Inbox was praised by many, but just because a Google product is good, doesn't mean it will survive Google's infamous chopping block. Nope, despite Inbox's success, it joins the Google Cemetery (yes, that's a thing). Though this is rather upsetting for many, it doesn't really come as much of a surprise. I had the feeling like Inbox wouldn't last much longer when development stalled and many Inbox features started making its way to Gmail. I jumped back to Gmail even before Google announced Inbox's demise, but that doesn't mean I don't miss Inbox. Luckily though, Android users now have a new e-mail app to fill the void left by Inbox, and it's called Spark.
Spark is basically everything Inbox was, but slightly better for a number of reasons. For starters, it's still an active app. Secondly, the developer is extremely open to user feedback, something Google has never really been good at. Lastly, it's highly customisable, something third-party apps will always be better at than official (first-party) apps. I've used it for a few days now (I signed up to beta test it) and I'm pretty happy with it. It bundles my emails and allows me to easily archive (or delete) them all in one tap. I can set it up to only notify me of important e-mails rather than all my e-mails (great for filtering out automated but still important e-mails), and one of my favourite things about it (which I also loved from Inbox) is being able to pin e-mails to the top of my inbox so I will always see what's most important first.
There's plenty of other features as well like scheduled sending, reminders and follow-ups, it even has features focused around teams, making it easier for you and your colleagues to work together. You can read more about the app on the devs blog post.
If you want to give it a try you can download it from the Play Store (it's been on iOS for a while now). Or if you have any other suggestions for people who miss Inbox, leave a comment and lets see what some of the best e-mail apps are for mobile.
