Action Builder to send 2 emails at once

I would like  to know if it is possible to send two different email with one click?

I have one button that email's a summary of what was approved. .Then I have another button that submits a XML file to SharePoint for processing by nintex. I would like to eliminate one step if possible by combining two actions into one button is this possible. And if I do not use the action builder what can I do.
