Good idea but...
In theory this is a fantastic idea. The problem is it doesnt seamlessly integrate with Apples native e-mail application.
Another issue is that it automatically includes an advert for the apps manufacturer on the bottom of every e-mail sent, however this may not be the case with the pro version.
The bottom line? This will produce fantastic looking e-mails, but it will take you four times as long to produce them.
