How can I either add a border around the entire inner background so the email is contained in one box not each individual text or image block? Or how can i change the color of said border in a pre-designed template provided by Constant Contact.
Thanks for reaching out to the Community! Outside borders are built into the templates, so your first step is to select a tempalte with the border style you like. The adjustment of the border colors depends on the editor the tempalte is using.
To make sure you have all the available options I copied a couple of our 3GE templates into your account.
