Advertise to grow the email list? Shanfelt says yes.

Sure, Eric Shanfelt, CEO of Nearview Media consulting told the audience at the 2025 Niche Publishing Conference, “The number one job of your website is to capture an email.”
However, the website is not the only way to grow the email list. He advised clients to advertise on social media such as META and LinkedIn to achieve their audience target goals.
The upside is significant on a variety of levels. The cost of an email opt-in may be $3 to $5, however, publishers can command much higher prices for first-party data-influenced advertising. CPMs increase by 50-200% for data -targeted audiences and some publishers report getting $35 to $100 CPMs for newsletter ads.
Finally, publishers can resell leads for 5x or more to partnering advertisers, depending on the category.
