The A.I.D.A. formula was popularized in the late 19th century by E. St. Elmo Lewis. He introduced the concept as a way to explain the stages a consumer goes through in the buying process. E. St. Elmo Lewis initially developed the formula to explain the stages of the customer's journey from the moment a brand or product attracts their attention to the point of taking action (like making a purchase).

It's worth noting that while E. St. Elmo Lewis is widely credited with popularizing the concept of A.I.D.A., the idea of guiding a potential customer through various stages in the decision-making process has been a fundamental aspect of sales and advertising for a long time.

Over the years, A.I.D.A. has been adapted and expanded upon to fit various marketing contexts and strategies, but the core idea remains influential in modern marketing and advertising.

Here's a breakdown of the A.I.D.A. formula and how it can be applied to a sales email:
