Hi Rachel,
Imagine you never had to deal with these kinds of issues again?
Well, I'd like to introduce you to Knak. Knak is a Marketo responsive email and landing page builder, built for Marketers. You simply select the template you'd like, customize it for your brand (colors, logos and social links) and then bring that into Marketo. From there it just works. We've added all the Marketo editable regions, so you're off to the races.
We test using Litmus, so it will work for all devices, including Android. I think you'll be pleasantly surprised.
Simply go to
www.knak.io. You can build your first template for free to try it out!
