Howdy - this is just an announcement, but I'm pretty excited,
Last year, I took the plunge in using Foundation for Sites in an app I've worked on since 1999 called, Dada Mail. Dada Mail is a self-hosted mailing list manager (announce and discussion lists). Lots of installs of the app, for sure.
Foundation for Sites is working really well for us! It was a large job to convert to hundreds of HTML template views we were using to speak Foundation, but it was worth the effort.
Now with Foundation for Emails becoming a little more mature, I've decided to also leverage it for all of Dada Mail's email templates, since well - a lot of what Dada Mail does is send out email, both for mailing list messages, and transnational things like subscription confirmations, notifications, etc.
This can all be found in v10 of Dada Mail, which just got its first alpha release (so things are still a little rough around the edges). Announcement of this can be found here,
The email templates creates is itself is on github,
If you're an expert on Foundation for Emails, working with Dada Mail to customize the app for your clients should be an awesome experience, as you can just start out with the default theme available, which is all written in Inky and are compiled using the workflow described in Foundation's docs, and go from there. Dada Mail will also support inlining of CSS and minifying HTML/CSS in its own workflow, so you won't need to do that before handing off an email template to it (but it won't hurt).
I've started writing the docs for that, as well (this link will get outdated, soon!)
Dada Mail is self-hosted, and it usually gets its updates picked up by app installer services, so once it's available, Foundation for Email-based email templates will be utilized by potentially... a whole lot of people.
I can update this thread as things develop - feel free to sign up to Dada Mail's own mailing list to also get updates,
Thanks for the great framework, Team Zurb!
