For those who want a powerful and comprehensive email app.
Airmail is a powerful and comprehensive email app that originated on the Mac and has made its way to iOS. The iOS version contains all of the powerful features of the Mac app in a much more portable package. Users can have multiple email accounts from a variety of email services, a unified inbox with color-coded mailboxes for each account, complete support for folders and labels, thread viewing, PDF creation, HTML signatures, aliases, email tracking and much more. On top of that, if you use Airmail on your Mac, then you can go for the iCloud syncing that will sync all of your accounts and preferences without any effort from you. With iOS 11 on your iPad, Airmail fully supports Drag and Drop, so you can easily get new attachments into your emails.
Why we love it
Airmail has a nice interface that is easy to use and it has a ton of powerful features that make it easy to manage your email inboxes. Plus the iCloud sync means you can have all of your accounts and preferences synced from the Mac version without any extra effort. When you receive an email attachment, Airmail quickly shows you a preview so you don't have to open it up in another app right away. When you're ready to open the attachment for editing or commenting, just tap the Share button in the top right corner. The app also supports email tracking, so you'll know right away when your recipient opens your message. The only drawback is I can't find a way to have Airmail track emails by default.
