This is a useful article from Campaign Monitor exploring high-performing subject lines used in retail email campaigns. It breaks down real-world examples and highlights what makes certain subject lines more effective at capturing attention and encouraging opens.
What’s particularly interesting is the insight into why people actually subscribe to email lists in the first place. Research shows that 28% of subscribers sign up to a company’s email list to stay informed about updates and new products, while 27% do so specifically to receive discounts and save money.
This balance of intent is important for marketers to understand, as it reinforces the need to create subject lines that both inform and offer clear value to the reader.
