"We booked 6 newsletter slots in a single afternoon. The targeting filters are incredible โ we found audiences our paid social could never reach. ROAS was 4x what we expected."
"I listed my newsletter on a Friday. By Monday I had three sponsor inquiries and closed my first deal for $400. SponsorStack is the easiest money I've ever made from my newsletter."
"We replaced 30% of our influencer budget with newsletter sponsorships through SponsorStack. The engagement is higher, the CPM is lower, and the audiences actually convert. Game changer."
"I used to spend hours cold-emailing brands that never responded. Now sponsors come to me. I'm making $2,800/month from my 15K tech newsletter โ fully on autopilot."
"The analytics dashboard alone is worth the $49/month. I can see exactly which newsletters drove signups, optimize in real time, and build relationships with publishers who become repeat partners."
"The creative approval process is chef's kiss. I've never had an ad go out that felt off-brand. SponsorStack actually cares about the reader experience, not just closing deals."
