Pierre (The Venture Insider - 100k subscribers)
“Subletter Optins played a key role in growing The Venture Insider. Within just a few weeks, we gained over 20,000 new subscribers — but more importantly, we saw a noticeable boost in engagement across our entire newsletter. Open and click rates improved significantly, which had a direct impact on our sponsorship revenue. It's been a powerful growth and monetization tool for us.”
