Your buttons appear in emails & forms! They also appear on-site if you keep "write a review" enabled. Use the branding section to make sure they match the look & feel of your brand.
Just head to Branding, then scroll down. The third section is where you'll find Buttons. Here, you can choose from a set of options on button color, button text color & button shape. If you want to change the primary or secondary color, just head one section up to 'Colors'.
Now you have on-brand buttons! ☀️
