Identify the element you want to embed. This could be a video from YouTube, a form from Google Forms, or a survey from SurveyMonkey. Go to the platform where your element is hosted and look for the "Share" or "Embed" option. This is usually found in the settings or options menu. Copy the HTML embed code provided. Paste this code into the HTML section of your email template.
For example, to embed a YouTube video, click on the "Share" button under the video, select "Embed," and copy the code that appears.
