CrossLetter — The easiest way to grow your newsletter through real partnerships. Growing a newsletter is hard. Paying for ads gets expensive fast, and organic social is a grind that feeds someone else's algorithm. Cross-promotion — recommending each other's newsletters to aligned audiences — is one of the most effective (and free) growth levers available. The problem? Finding the right partners is tedious, scattered, and usually involves a lot of awkward cold outreach. CrossLetter fixes that. It's a free platform where newsletter creators list their publications, signal they're open to cross-promotion or sponsorship, and discover other newsletters worth partnering with. No middleman taking a cut. No algorithm deciding who sees what. You find a good fit, you reach out, you build a real relationship. CrossLetter gets out of the way and lets that happen. What you can do with CrossLetter: List your newsletter with your audience details, niche, and partnership preferences Browse and discover newsletters open to cross-promotion Find and connect with potential sponsors Create curated collections of newsletters you recommend Who it's for: Newsletter creators, independent publishers, and brands looking to reach engaged, niche audiences — without burning budget on paid acquisition. Whether you're at 500 subscribers or 50,000, cross-promotion works when the audiences align. CrossLetter makes finding that alignment simple. Free to use. No gated features. No catch. Built by newsletter operators who got tired of doing this the hard way.
