Reletter is a first-of-its-kind newsletter search engine. We're on a mission to index every email newsletter on the web (starting with Substack, LinkedIn and Ghost newsletters).
If you're looking to sponsor a newsletter in your niche, get featured in newsletters or even cross-promote your own newsletter with other writers, Reletter was made for you.
We aggregate dozens of data points from all over the web for every newsletter including contact info, subscriber numbers (where available), chart rankings (Substack only) and social media accounts.
Our goal is to save you countless hours manually researching newsletters and help you to make better decisions.
