To add a new button layer to your email design, you can click on any Column or Hero layer, then select the Button option from the Quick Add dropdown menu, then click the Add + button to insert the new button layer into your layout.
After styling the button to your liking, you can specify the clickable URL by clicking your Button layer in Figma, then clicking the Settings button, and pasting your URL into the Clickable Link URL input field; this will ensure that your button opens up that URL in the browser when it's clicked
For links added through Emailify's link fields or Figma text hyperlinks, the HTML export omits executable javascript: and vbscript: destinations. Dynamic template links and image source URLs keep their existing behavior.
You can apply settings in bulk by opening Settings, then selecting multiple Emailify layers of the same type in Figma. Any setting you change will be applied to all selected layers.
