Get email messages in Xamarin

GemBox.Email is a standalone .NET component with cross-platform support. You can use it on non-Windows platforms and frameworks like Xamarin and Mono, enabling you to use it on Android and iOS mobile devices.

By using GemBox.Email you can process your email messages (send, receive, load, save, convert, and edit EML and MSG files) from the native mobile apps.

The following example shows how you can get the first email message from the INBOX using the ImapClient in Xamarin.Forms application.
