The (web based) software I am working on needs a way for users to be able to customize an email template.
I'm familiar with TinyMCE et al. web based wysiwyg editors. However they strive to produce valid (x)html markup, with heavy use of style sheets. All of which won't render nicely in email clients (yes, I'm looking at you.. outlook 2007).
Is anyone aware of one that can be configured for generating email friendly html?
You can take a look at livepipe http://livepipe.net/control
The TextArea tab in that page has a nice simple wysiwyg editor that might suit your needs. It is javascript based and uses the Prototype framework.
