Thanks @barberleo for the question. Yes you can have an e-mail address as a data element. You can use the URL feature and then have the HTML mailto call.
Here's a screenshot where the above code goes.
Once you have the URL for the mailto in place you can view it on the dashboard when you click on the field you want. In this case I placed the URL for the name. You could have the email in the table too if you want.
When you click on name it will show the URL to invoke the mail client and mail the person. Hope this helps, any questions, please let us know.
