I am always lookout for a good email client (iOS and OS X). I used Sparrow years after it was acquired by Google and had no support. It was a great email client. Surprisingly, the iOS client that works for me now is Outlook.

I just checkout out SlideMail from app store (1.0, I guess?) Looks simple and well designed, but confusing UX. Why 'All Mail' is called 'Done'? Compose makes it easy to pick the recipients, but there is no way to see their email address. It just shows their name and picture. I can't tell if I am sending an email to their work email or personal.

Would be cool to try out v2.

>If you’re on iOS and have a Gmail account

Should have called it a better gmail client.

Spark Mail already does what SlideMail aims to do really well.

Important emails are consistently shown at the top. It does that so well that I don't even see all the incoming noise that would otherwise bury the important stuff, though its all there when I'm ready to look. When I check the same mailboxes via other clients, it's just chaos.

Swipes and snoozes like Mailbox, but you don't give them server-side access to your data like Mailbox does. Nor do they have Condi Rice on their board.

Amazing degree of configurability. Saved searches, customized swipe actions, integrations with Dropbox, Google Drive, Box, OneDrive, Evernote, OneNote, Readability, Pocket, Instapaper.

I've tried so many clients. This is the one.

What's 'open' about it?
