I started using SFMC's "Basic" templates as well as some "Themed" templates for one of our customers. But as we started sending emails, even though we had tested the emails on a few platforms, it seems like we probably shouldn't have relied on these built-in templates.
The buttons did not look good on mobile devices and were trimmed and cut short on Outlook Windows. The double column modules were disappointedly not mobile-ready. We counted so much on drag-n-drop. Now I feel like I should build everything from scratch.
I am wondering if there is a template (be it basic or themed, etc.) which is both responsive and mobile-ready and works fine on most known platforms? You can also lead me to a best-practices page (the dos and don't) where we could have our MVP (Minimum Viable Product) concerning email. I appreciate your help in advance.
