Sign Customiser now gives you complete control over the content and layout of custom design submission emails. Using a powerful template editor with Mustache syntax and Markdown support, you can structure these emails exactly how you need them for your workflow—whether that’s optimising for forwarding to manufacturers, integrating with your CRM, or simply making the information easier to scan.
