I wanted to Pay you guys, so bought PDFExpert Premium

What do I say! Not everyday you come across products where you want to pay for them by yourself. Like literally desperately. And all this because I dont want Readdle to close down ever, for lack of cash.

Anyway, this is hands down the best eMail client on iOS. I have tried all the other ones and they have one or more limitations, for example the next best one is Outlook - great design, features etc., but it wouldnt allow to pick up attachments from iOS ‘files’ app. Its small things like these. You guys have paid so much attention to every single thing.

I had long been a big fan of Inbox by Gmail.. and I cant think of why they decided to shut it down. Who takes such funny decisions in Google?

I am hardpressed to think of any feature request for Spark, however if someone puts a gun to my head and asks me for one, it will be one of the features from Inbox - of categorizing mails by their content - Travel, Finance, Shopping etc.

Thanks a ton and please ensure that you guys keep on thriving and surviving.

Overcomes the limitations of gmail and the Mail app by Apple

I had installed their application on my MacBook. Even though I don't use emails much, I always noticed that I got a notification from spark even when it's running in the background before I got one on my default mail app.
I installed this today on my dad's iPhone X because he was frustrated at lack of instantaneous emails on the mail app in iOS 11. Which apparently only pushes emails when on power and connected to wifi.
This app overcomes that fault in the iOS mail app.
It also incorporates the categorisation feature of gmail which doesn't allow us to login with other email accounts.
So all in all this is a great app with good categories, features and basically superior UI than what current options provide.
Would definitely recommend to anyone who's facing any problems with email.

Best email app for iPhone

I've been using SPARK for last few years and tried out many email apps but this one stands out to be the best app for emails. My second choice is Microsoft Outlook. Day by day Spark app development team keeps improving it a lot. I've hardly faced any issues till now except Gboard issues recently. Otherwise I'm really satisfied and highly recommend it more than any other email apps available on the app store.

Cheers to the developers!
