In a Windows Phone 7 app, sending an email requires an instance of EmailComposeTask. EmailComposeTask is really easy to use and self-explanatory:

EmailComposeTask emailComposeTask = new EmailComposeTask();

emailComposeTask.Subject = "message subject"; 
emailComposeTask.Body = "message body"; 
emailComposeTask.To = "recipient@example.com"; 

In Windows 8 Metro app, there’s no EmailComposeTask. Instead, you create a “mailto” –uri and launch it:

var mailto = new Uri("mailto:recipient@example.com"); 
await Windows.System.Launcher.LaunchUriAsync(mailto);

But when compared to an EmailComposeTask, this only fills the “To” –part, but what about the “Subject” and “Body”? Well, the mailto-syntax allows you to define these as query parameters. For example, here’s an example of defining the “subject”, “body” and “to” –fields from code. The uri is automatically escaped by the platform:

var mailto = new Uri("mailto:?to=recipient@example.com&subject=The subject of an email&body=Hello from a Windows 8 Metro app."); 
await Windows.System.Launcher.LaunchUriAsync(mailto);


With this knowledge, it would be rather easy to build a custom EmailComposeTask for Windows 8.

Hey, a question. the tab and end of line chars are being removed from the email body. how do I make the MailFormat = to text?

Comment by Mikael Koskinen

Good question. I'm not actually sure how this should be handled. It's been some time from your question so I wonder if you were already able to solve this?

My email app is Outlook and when executing the suggested code, the To field is not prefilled with the desired address...

Would like to see an example of a very custom e-mail, say one that includes debug info about the system as developers may like to implement in part of crash reporting. I am having trouble getting newlines to show up in the e-mail body either with rn or <br/>
Thanks in advance!
