What are the best practices that you follow when it comes to designing templates for your emails and landing pages?
Hi Karina Guerra,
I would say it depends how you want to design it.
First time when i designed a landing page i used Bootstap software for that and there are perpendicular classes that you should call to make the region editable. Below link might help you a little bit or i would suggest you to download any template and go through the source code.
