Commission$20 CPA for paying users, $0.20 CPA for FREE users.
Grammarly is one of the most recognizable writing tools on the market, and its affiliate program benefits enormously from that brand awareness. The $20 CPA for premium conversions is decent, and the product essentially sells itself given Grammarlys massive user base and strong word-of-mouth reputation. The free tier acts as a powerful conversion funnel where users sign up at no cost, earning you $0.20, and many eventually upgrade, though you only earn the premium commission if they convert during the cookie window. Conversion rates tend to be strong because the free-to-paid upgrade path is well-optimized. The main drawback is the $0.20 free signup commission, which is negligible, and the $20 premium CPA is moderate compared to higher-ticket SaaS programs. There is no recurring commission, which means you miss out on ongoing revenue from long-term subscribers. The program is excellent for content creators, bloggers, and educators whose audiences regularly write, particularly students, professionals, and non-native English speakers.
