The article highlights the importance of messaging in onboarding new customers to a product, as it can help demonstrate value and ensure continuous engagement. It emphasizes that most onboarding efforts focus solely on the initial interface interactions, neglecting the crucial 30 days following sign-up. Successful onboarding is about providing ongoing value through messaging, which can be used to show users why they're there, what they can accomplish, and what to do next. The article suggests a series of five messages that can guarantee new signups get the most out of the product: a welcome message, follow-up message, activation message, education message, and nudge message. Each message aims to sell the value, make action easy, use active language, set expectations, and educate users based on their behavior. By using these messages collectively, businesses can convert new signups into engaged users and provide long-term value for both themselves and their customers.
