The Intuit Mailchimp report, *The Art of the Opt-In*, highlights key factors that influence consumer engagement at the sign-up stage for email and SMS marketing. It reveals a significant disconnect between marketers' strategies and consumer preferences. Many marketers overestimate how much data consumers are willing to share, especially sensitive information like phone numbers. For example, while 65% of brands request phone numbers in sign-up forms, only 28% of consumers are comfortable providing them. This suggests that brands often misjudge consumer trust, particularly among different age groups. Trust is notably higher among Gen Z, with 39% believing brands will adhere to privacy laws, compared to just 19% of Baby Boomers. The report also points out that only 8% of marketers achieve opt-in conversion rates above 20%, and less than one-third consider their email and SMS lists to be of high quality. A lack of automation is partly to blame; only 21% of brands have fully automated their campaigns. Successful brands focus on high-intent moments, such as when a consumer is browsing or checking out, rather than relying on generic pop-ups. The data shows that brands with effective automation and a strong omnichannel approach see better results. Those identified as "List Quality Leaders" are three times more likely to have full automation in place and utilize welcome series more effectively. Marketers struggle to turn data into actionable insights. Only 30% utilize preference data, and just 29% consider browsing behavior despite these being critical for engagement. The research emphasizes that relevance comes from clarity and not sheer volume. With fragmented data, even good intentions can fall flat. To build trust and foster long-term relationships, marketers need tools that integrate behavior signals, automations, and insights across channels.
