e-Flyer - HTML text and graphics

Looking for any tutorials on how to create an e-Flyer using X10.
mailChimp is not on option, just looking on how to design in Xara, and reassemble the text and graphics as an e-mail ad.
The code xara generates, does not hold the WYSIWYG in the email.
What 3rd party programs (besides the listed) can be used to reassemble what is created using Xara?

Xara 10
Photoshop CSx
Flash CSx
FireFox
