I've been using the Data Assist pages for other purposes; select, insert, update, pages etc. But haven't used for any email development.
So if I set up a database connection then I can access email message features with DataAssist Pages?
I'll create a database for this site and see what happens. It's not what I planned just wanting to send a simple email form like I have done so many times with Universal Email. But I'll see what happens...
Hope it works.
