If you're focused on creating and scaling a newsletter, especially in a media or content-focused business, beehiiv is your best choice. Its built-in referral tools and monetization options make it ideal for newsletter operators looking to grow their audience and revenue streams. However, if your needs include product lifecycle emails or simple automation, then beehiiv might not suit you.
On the other hand, if your primary goal is visual web design with detailed customization, Webflow is the better option. It provides pixel-perfect control and is ideal for designers and agencies that need a robust CMS for marketing sites. Keep in mind that it has a steeper learning curve and can become costly with increased CMS usage and traffic. If you're looking for something simpler or aiming to build complex web applications, Webflow may not be what you need.
