People are becoming more and more suspicious of Mobisystems. Although I don't see the advertising myself anymore, I wonder what will come next. That's how many people feel, the name AquaMail is no longer what it used to be.
Maybe there will be more advertising? Maybe you have to pay more for more features?
That's why I do it like many others:
You test, observe and discuss other good email apps. And when the time comes when AquaMail does even more such things, you can switch to another e-mail app relatively quickly. Then the inhibition threshold is no longer high.
