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.
Freezes too often, irritatingly so

I used to love Spark for the longest time. But something happened in the process of them upgrading their app for adding more collaboration features - it has started to freeze almost at all times. Extremely irritating for an e-mail app and this puts users off big time. Fix this guys or you all will soo be history. I want my e-mail app to just work the minute I launch it - shouldn’t have to wait around looking at the screen to even access emails. It freezes on launch and if you have it open, everytime you access it. Really irritating.

Thanks for a useful email app
Thanks Word
I was having problem in attaching documents to my mail in outlook installed in my iPad. Lot of complaint to MS yielded no result. After lot of search for a suitable email app, I found this email app. After using this app for few days, I found this app as extremely helpful, attaching documents were not a problem at all, moreover it provided the facility to change colour of some of the sentences/words in my email. My only request to the developers is is to add the facility of adding an image within the Mail body. Thanks to the developers for creating this useful app.
