The beehiiv Ad Network enables brands to tap into these trusted audiences at scale, without needing to manage individual publisher relationships. This allows brands to efficiently test, optimize, and expand campaigns across hundreds of newsletters. “beehiiv has been a great addition to our media mix, allowing us to advertise in newsletters in a way that’s quick, effective, and easily scalable. Not only do we see strong performance across multiple products, aligning with our target CPA and ROAS, but the beehiiv platform and team also make the process much more efficient than traditional newsletter advertising.” — Aviad Eilam, VP of Growth & Strategy, Particle for Men ## Results Following strong performance, Particle for Men expanded from a single Face Cream campaign to running three simultaneous campaigns across multiple product lines.
