Since iframes are not viable for email marketing, marketers often use other techniques to deliver similar content and interactivity:
Images with links: You can create visually appealing images that link to your landing pages. This way, users can click on the image to view more information. GIFs: Animated GIFs can be used to showcase multiple products or features within a single image. They are widely supported in email clients and can make your emails more engaging. Call-to-action buttons: Use buttons with compelling text to drive users to your website or specific landing pages. These buttons are often styled with CSS and are supported across most email clients. Embedded video thumbnails: Instead of embedding the video directly, include a thumbnail image of the video with a play button overlay. When users click the thumbnail, they are directed to a landing page where the video is hosted.
