When you open the Email app for the first time, a setup wizard will automatically create three branded email templates for you. The app pulls this information from your Brand Profile. If you haven't filled out your Brand Profile yet, you'll be prompted to do so first.
Overview: Your business name and location (the first one listed).
Platform Profiles: Your website URL.
Once the templates are created, they will appear on the Templates page. These templates will use your brand's assets as default settings for future email campaigns. For example, any text block you add will automatically use your brand's font, and any button you create will be pre-loaded with your brand's colors and fonts.
