The best mail app
TauriuxxLTU
I have tried many email apps before since I have a few email accounts: work, university, personal. However, none of them worked as smooth and seamless as Spark. I've been using this app for almost a year and I'm not going back to any other email application. Besides that, the accounts sync functionality between devices and platforms is just like a cherry on top which makes this app even better.
Great app but not working as it should
Phant0m2707
At first I was very excited about this app and all features that it has. I think it is very well thought through and has high potential. But main problems currently are that emails are being loaded very slow. 50% of time sent emails get stuck in outbox. If you search for some older emails attachments are loading super long. Furthermore newly received emails are taking forever to load. I receive notifications from other apps long before it is shown in spark. This makes for me this app quite frankly unusable. I’m hoping very much that these issues will be solved and it will be possible to enjoy it to it’s fullest potential.

I have a dozen different emails for my businesses, tried several other email apps, all of them had some flaws. But when I found Spark a year ago, haven't had a problem: quick set up, easy to add any emai account, awesom UI! A must for anyone having didficulties handling multiple email accounts.
