SparkLoop

Hey Product Hunters! Louis, cofounder of SparkLoop here 👋 Two years ago we launched Upscribe — the first newsletter recommendations network. And it has grown to become hands-down the easiest way to grow your newsletter for free. We've helped top newsletters like Morning Brew, James Clear, The Hustle and thousands more add over 10 MILLION (!) high quality, engaged new subscribers. But — if your newsletter's not quite as big and popular as Morning Brew or The Hustle (yet) — it can be super hard to find the right newsletters to partner up with. That's why we're launching Newsletter Radar today. In just a few clicks, you can: 1. See a list of all your audience's favorite newsletters (ranked by how many subscribers you have in common) 2. Discover thousands more newsletters that our algorithm thinks are relevant to your audience 3. And invite the ones you like best to partner up with you on free recommendations The result: In less than 15 minutes, ANY newsletter should be able to find at least 5-10 (but really more like 50+) perfect newsletter partners, and start growing 3-10x faster by recommending each other. One of my favorite things about Newsletter Radar (and Upscribe) is that it works with 25+ newsletter platforms (including beehiiv and ConvertKit). So you can discover 100% of the very best newsletters you should be partnering up with... not just the 0.5% who happen to use the same newsletter platform you do! Happy to answer any questions 🥳

Hey @louisnicholls_! Newsletter Radar sounds incredibly useful for those of us trying to grow our subscriber base. Can you share more specifics about how the algorithm identifies relevant newsletters for partnerships? Also, are there any particular metrics or data points that it prioritizes to ensure a good match?

Really excited to see how this feature generates synergies and help the newsletters to grow.
