Install the code once in a reusable email template. The featured question updates when a new quiz goes live.
If you see HTML code, move it into a Custom HTML or Code block. If the question is old, confirm that the next quiz is live. Some email apps cache images and may still show the previous question. If your editor cannot accept custom HTML, choose URL link in Atrivial and add it as a normal email link or button. Substack requires this link format.
