Classic email button fill and rounded corners

For school administrators using GiveCampus Outreach. Controls can differ between the classic email editor and the newer Composer editor.

In the classic Outreach editor, select the actual button block. Use Background color for the fill, rather than text color; use Border and its Radius value to round the corners, and border width/color for the outline. The email plugin applies these block controls to the email-button element. These controls support styled rectangular/rounded buttons, not arbitrary vector shapes. Send a test email because recipient email clients can render styling differently. The newer Composer has different controls, so identify the editor before using this click path.
