In the episode "How to launch a media-level newsletter, not just another marketing email" of the Content Logistics podcast, Ashley Guttuso shares her insights on the importance of email newsletters and how to make them effective. She emphasizes that the key to a successful newsletter is to make it about the recipient, not the company. She also suggests giving readers the option to choose what kind of emails they want to receive, rather than forcing a broad opt-in to all company communications. For SaaS companies, Guttuso sees newsletters as a crucial tool in customer success and marketing, and advises that they should be a collaboration between marketers, the success team, and sales.
