Stack Influence Achieves 1006% ROAS With Newsletter Ads

Situation:

Stack Influence is a platform that helps brands collaborate with over 11 million micro-influencers by paying them in products instead of cash. Led by CMO William Gasner, the team needed a reliable way to reach high-intent B2B and B2C leads and drive awareness for its innovative offering.

Challenge:

Despite a strong overall marketing mix, Stack Influence faced difficulties scaling newsletter advertising. The main issues were identifying high-performing newsletters for specific ICPs, inconsistent open rates, trust in quality, and the manual nature of sponsorship placements.

Solution:

Stack Influence adopted beehiiv’s Ad Network to scale newsletter ads with precision and ease. The platform offered a centralized marketplace, allowed precise targeting by ICP, ensured high content quality, and replaced outdated “Pay Per Send” models with a “Pay Per Click” approach—making ad performance transparent and ROI-driven.

Results:

• 13x increase in newsletter campaigns (from 4/month to 50+)
• 1006% return on ad spend (ROAS)
• 21% increase in traffic and leads
• 24% drop in customer acquisition cost (CAC)

As CMO William Gasner put it: “beehiiv has taken the guesswork out of newsletter advertising and turned it into a science.”
