Button blocks

How to add and style call-to-action buttons in your email signature.

Buttons are clickable calls-to-action like “Book a demo”, “Visit our website”, or “Download our app.” They stand out visually and drive clicks to your most important links.

Button content

Setting	What it does
Text	The label displayed on the button
Link	The URL the button links to when clicked

Style

Setting	What it does
Type	Plain (solid background) or Stroke (outline only with transparent background)
Color	Button background color (for Plain) or border color (for Stroke)
Border radius	Corner rounding — 0 for sharp corners, higher values for rounded corners
Color presets	Quick-select from gradient and solid color presets for fast styling

Use Type → Plain with your brand color for primary calls-to-action like “Book a demo.” Use Type → Stroke for secondary actions that should be visible but less prominent.

Text styling

Font, size, color, opacity, line height, and formatting options for the button label text.

Size

Set the button’s Width and Height in pixels.

Layout

Padding controls the space around the button block.
