If you need to add any custom code in between any elements in your ✉️ Email frame, such as platform specific template/conditional tags, you can insert a 🧑💻 Custom Code layer to do this. It will be added as a Figma text layer, which you can paste your custom code into, and have that rendered out as plain code when the email gets exported to HTML.
Using the "Quick Add" feature to add new Emailify layers
Emailify allows you to build out your designs using special layout blocks and content elements that are added as layers to your Figma designs, and allows them to be exported out to HTML from the plugin.
To add these layout blocks and content elements, ensure that you have created at least one Emailify frame, and then click on that frame to automatically reveal the Quick Add Element context menu at the bottom of the plugin, then click the desired element, and click the Add + button to add it to the selected layer.
