Ratings and reviews

To start, I can't find my drafts. If I don't finish an email, I can never find it again (yes I look in the drafts folder, for all and a specific account) I'm not sure if I'm missing emails, the UI is limited to Priority and Other which isn't exactly helping me with my Inbox woes. After a month or two, I still cannot say I'm happy. It's nice that it's multiplatform, but I still have to manually setup 18 email accounts on every new platform...not so intelligent. The mobile interface is a bit strange and has bugs that I can't reproduce well enough to report. Try this app maybe you'll like it... I'm worried I'm missing important emails still.

I so want to love Spike. it is a great email client with a clean interface, great "conversational" type of presentation of email, which I like. Unfortunately, it lacks some really basic features. UPDATE: While they have yet to add the needed, basic features, the response from support has been impressive. They have been quick to respond and open to suggestions. Hopefully they will consider incorporating the needed features. I will continue to try at times to see if the features are there.

I've been waiting years for an app like this for Smartphones and computers; something substantially different, but yet retains the same functionality as traditional email clients. I've just only begun to use it, but so far I really like it. UPDATE: After updating to Android 11, the app lost functionality. I uninstalled and reinstalled the app, and it appears to be working now.
