Sidebar placement

This ad location appears in a sidebar or column, often to the right, next to the main content of your email newsletter. This placement is less visible than a header or body placement because it is on the side and does not directly interrupt the flow. However, it can still be an effective way to promote products or services. When using this placement, it's important to make sure the ad is still visible but not too flashing or disruptive to the reading experience. Also, depending on the reading screen’s size, there might not be enough space to display the sidebar.
