Haha, glad to hear it, John! It's actually a new version of a resource I had out for a long time. Explore the rest of that site, too ;-) It has some educational products I'm working on, the first of which will be out on November 1st.
Hey, Lisa - All of these resources are still good options in 2017. If anything, they're more relevant than before since Google updated how Gmail supports some code in 2016, which makes the techniques described in the resources even more well-supported.
I also have a resources site I maintain that has a bunch more to check out at The Better Email. You should definitely check those out. Cheers!
Hey, Brandon - Just an update that these templates have been updated. You should be able to get the new code by going to https://litmus.com/community/templates/topic/32-launch-templates, picking the desired template, and opening it in Builder. Cheers!
