Pros
Pro Multiple ways of sorting emails
There are multiple ways to sort emails with Airmail. You can sort by unread, starred, attachments, conversations, dates, and many more criteria. You can even combine different criteria together.
Using these filters makes it extremely easy to quickly find any email you are looking for.
Pro Extremely customizable
Instead of forcing the user to work with their email the way Airmail developers would want, it allows the user to customize and make the email client work the way they want because of the sheer flexibility of the application.
There's a lot of settings available in Airmail with which you can customize almost every aspect and functionality of the app. In fact, it's very easy to get lost in them and spend a lot of time tweaking and customizing everything to your liking.
