Apple does not provide a way to do this - and for good reason. Sending emails from the phone automatically introduces a lot of security risks.

I am willing to bet that the apps that do this use an intermediary server to which they post the data. When the data is posted then the server handles the sending of the emails.

To do this:

1. Send an HTTPS POST request to your server application.
2. From your server application, send an email via SMTP (or APIs built on top of SMTP).

Google AppEngine provides a simple and cheap way to create such a web service, running on top of Google's cloud-computing infrastructure. The sending mail from AppEngine help document includes detailed examples of how to send mail from your server application (assuming you use the Python version of Google AppEngine).

Unfortunately, there is no official feature for this but you could download a third-party library. Refer here for a couple of suggestions.
