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.

Thanks Word ,

Thanks for a useful email app

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.

Well Best best best, I would have given it a 10 star rating if allowed.

Well, This is the best and most convenient app(not just mail) I have EVER used on iphone. The notifications are real time and quick which is the biggest issue with native mail app in ios and the inbox and work done on every little detail makes it a charm to use the Spark mail app. The readdle apps documents and spark have made my phone life so much easier. Thankyou and keep both these apps like this only, they are already the best they could be.
