Of course, many users are not convinced with the management carried out by the native Apple application, Mail, so they opt for other email clients to manage their accounts and in this case AirMail is within these options that often used by many of these users.
It is true that these mail clients are not perfect, but they add options that we cannot find directly in the native Apple application. In this case AirMail 4 receives the new version 4.0.3 with several improvements and almost all of them for the Pro version of the app, which is obviously paid.
New design, a new appearance for the inboxes, new search options, with new themes and more personalized actions are some of the novelties that are added in this application that allows email management somewhat different from what we can find in the market. The truth is that I personally stopped using this app for e-mail a long time ago, but I may decide to try this version, although it is true that the payment of the Pro version is what we need if we want to get the most out of it to the client.
In this case the possibilities it offers are many in its full version but the price of the application prevents more users from using it, the Pro version is around 11 euros, so if you are not a "hard" email user With multiple accounts and such, it may be too high an expense for you.
I bought the application paying at the time. I do not want to pay 11 euros annually, which is worth the pro version, but it seems unfair that every time I open the application, the announcement that I go to pro paying appears. It's a bit embarrassing, since I paid to install it and am really considering uninstalling it.
