Best for: Writers and thought leaders who want the simplest path to a paid newsletter
Substack is the largest newsletter platform by publication count and offers the simplest zero-cost setup for creators starting out. Its built-in recommendation network surfaces new newsletters to readers of similar publications for free, which beehiiv's Boosts feature charges per subscriber to replicate. Publishing is free regardless of subscriber count, and paid subscriptions can be activated immediately. Substack's audience and community features have expanded, and the platform is moving toward ad-supported content alongside subscriptions.
Tradeoff: Substack takes 10% of subscription revenue, which compounds into a significant cost as paid subscriber counts grow. beehiiv's 0% take rate is a real financial advantage at scale. Substack also has more limited design customization, lacks an ad network, and does not support advanced segmentation or automation.
