Reviewer scorecard
“Combined transactional and marketing email with a clean API. Event-driven automations are perfect for SaaS.”
“No API to speak of. It's a publishing platform, not a developer tool. Built-in audience is the value proposition.”
“The email editor is modern and intuitive. Templates look professional without wrestling with HTML tables.”
“The simplest way to start writing and getting paid. The network effect brings readers you wouldn't find elsewhere.”
“Combining transactional and marketing email eliminates a tool. The SaaS-specific features are well thought out.”
“10% revenue share is expensive at scale, but the built-in discovery and reader network provide real value.”
