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.

🧑‍💻 Custom Code layers can only be added directly to an ✉️ Email frame as a way to inject custom code blocks between 🚣 Content Row, 🦸 Hero and 🎁 Row Wrapper layers in your email design.
