Experience Day gift vouchers were first popularised by the pioneering UK business Red Letter Days. The business, which was established in 1989 by serial entrepreneur Rachel Elnaugh, is headquartered in Borehamwood in the offices of its parent organisation, Buyagift. One of the first companies to see the possibility of giving intangible experiences as gifts was Red Letter Days, and the idea has since become quite well-liked. The Smartbox group, a French company that provides gift experiences across numerous European nations, presently owns the business.

Red Letter Days have provided a variety of events over the years, including bungee jumping, paintball, hot air ballooning, skydiving, racing, and spa days. Entrepreneurs Theo Paphitis and Peter Jones bought the business in 2005, and they successfully turned it around, raising its annual turnover to almost £20 million. Later, Buyagift purchased the business, beginning a new phase in its development. Red Letter Days still thrive today, providing its clients with distinctive and unforgettable experiences.
