How to use this block

Treat the component as one production section inside a larger message system. Keep the shared classes and wrapper rules intact, then adapt the copy, imagery, and links to the send.

Use this block when...

  • Use as the primary action after a hero, proof block, or information section.
  • Keep to one button per section so the send has a clear next step.
  • Match the CTA label and destination URL to the campaign intent before exporting.

Keep in mind

  • Button copy should be action-specific and not rely on surrounding text alone.
  • Check contrast between button fill and text after applying brand colours.
