Quickstart: Sending an email message Windows Phone Store app using C++, C#, or Visual Basic

[This article is for Windows 8.x and Windows Phone 8.x developers writing Windows Runtime apps. If you’re developing for Windows 10, see the latest documentation]

This topic shows you how to launch the compose email dialog to allow the user to send an email message. You can pre-populate the fields of the email with data before showing the dialog. The message will not be sent until the user taps the send button.


  • We recommend that you be familiar with Microsoft Visual Studio and its associated templates.
  • We recommend that you be familiar with C# development.

Launch the compose email dialog

Create a new EmailMessage object and set the data that you want to be pre-populated in the compose email dialog. Call ShowComposeNewEmailAsync to show the dialog.

private async void ComposeEmail(Windows.ApplicationModel.Contacts.Contact recipient, 
    string messageBody, 
    StorageFile attachmentFile)
    var emailMessage = new Windows.ApplicationModel.Email.EmailMessage();
    emailMessage.Body = messageBody;

    if (attachmentFile != null)
        var stream = Windows.Storage.Streams.RandomAccessStreamReference.CreateFromFile(attachmentFile);

        var attachment = new Windows.ApplicationModel.Email.EmailAttachment(


    var email = recipient.Emails.FirstOrDefault<Windows.ApplicationModel.Contacts.ContactEmail>();
    if (email != null)
        var emailRecipient = new Windows.ApplicationModel.Email.EmailRecipient(email.Address);

    await Windows.ApplicationModel.Email.EmailManager.ShowComposeNewEmailAsync(emailMessage);
