Your email theme is the color that will be added to your email when it's ready to send through either your integrated email providers, OR if you're placing the HTML format in another email provider.
To set it:
1. Navigate to "My Profile" on the left side of the page. Click "Account Settings." You'll see the Email Settings theme color.
2. Click the color box, then adjust the color either by sliding the slider up and down, or by placing your mouse and clicking in the color selector. You can also use a specific HMTL color code if you know what it is, by typing it into the field just below the color box. In this example, #2f0cbe is the color code of the color that is selected. You can pick your own color by using a site like this: https://htmlcolorcodes.com/
3. When you're done, click back onto the page, out of the color selector, and then click the blue "Save" on the page to set your email theme color.
4. When you create an email newsletter, it will look like this- with your color behind the text- and your logo at the top.
