It's a simple, yet very powerful feature that makes it possible to create dynamic designs that look great with any dynamic content. ## How to enable text auto-sizing Auto-sizing (or text fit) is available for all text elements in the SendBetter editor. To enable auto-sizing in your template for any text element, make sure `text-fit` mode is selected. When the `text-fit` is enabled, you cannot adjust manually the font size. Switch to the `auto-height` mode to turn off text auto-sizing (or text-fit). Image showing where to find the text fit mode for a text element in the SendBetter editor
