Set label, link URL, and styling for email, inbox, and other channels. Button blocks add clickable call-to-action (CTA) buttons to your notifications. Configure the button label, link URL, and optional styling. ## Adding a button block 1. In Design Studio, select a channel. 2. Add a **Button** block from the block sidebar or toolbar. 3. Set the button label and link URL. 4. Configure button styles (padding, color, border radius).

## Button settings Select a button block to open the settings panel on the right. Here you can configure: * **Label** – Text shown on the button. You can use [variables](/platform/content/variables/inserting-variables) (e.g. "View `{{product_name}}`"). * **Link URL** – Destination when the button is clicked. Use variables for dynamic URLs. * **Alignment** – Left, center, or right. * **Background color** – Button fill color. * **Border radius** – Corner rounding. * **Border size** – Outline thickness. * **Padding** – Space around the button.
