You can do it using the tool Email from the Reporting Tab
You are going to need de SMTP server and the credentials that let you send the email.
After you have that info, just put the data of the email, and in the attachments section attach the file you just write.
From the image you attach, you can put the file in the first output and the email tool in the second output, in order that update first the file.
I hope it helps!
