Makes My Life Easier

I usually dread checking my emails because every time I do, it will be in the hundreds. Ever since I got this app, I managed to clear the mess and unsubscribe from newsletters pretty quickly. The synching is a bit slow but why complain when it does emails better than the official mail apps. This is an essential app for people who want to quickly check mail without spending too much time doing it. Highly recommend. -6
Best email app I ever used but most recent update has lots of bugs
Sahara108
I would want to thank you the developers for making a really great app. But the recent update with new Smart inbox broke everything. It suddenly pin all the emails ( I have to manually unpin 3k+ trashed emails, what a terrible experience). Also recent mark as read email keep popping up (randomly?). I want to subscribe to support the devs but those annoying bugs keep me away from the app for sometimes. Please address it asap

I am using this app for literally 10 minutes and I am in love with it! I’ve been trying to find this thing for my entire life!!! Due to my job complications, i have to use Outlook, Gmail and alias Gmail from my team. I’ve been wasting many days trying to sync these things together but it’s a disaster:- Most of the time Gmail doesn’t update changes from my Outlook. - I can make changes for my Gmail calendar from Outlook but not vice versa. So the whole process become very lengthy and time consuming.- I cannot sync my Gmail Calendar with my alias Gmail Calendar from my organization. So eveytime i need to add/edit my event i have to open the other calendar.Spark solve everything under 10mins!!Hey Spark Team you are doing great job!!!
