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 โ recommending each other's newsletters to aligned audiences โ 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 โ 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.

CrossLetter's answer
We're not a vibe-coded stack. We've hard-coded all tech around React and NextJS frameworks within Vercel, and use RadixUI and Tailwind CSS UX elements for optimal user experience. We're also integrated into Beehiiv for all automated communication and newsletters
CrossLetter's answer
Most newsletter discovery platforms either try to automate the relationship or take a cut of the transaction. CrossLetter doesn't do either. It's a discovery layer โ you find aligned newsletters, you reach out directly, you build the partnership on your terms. No algorithm matching you to whoever paid the most. No middleman fees. Just a clean directory of newsletters that are actively open to collaboration and sponsorship.
CrossLetter's answer
Because it's free, it's simple, and it doesn't try to own the relationship. Competitors tend to either gatekeep introductions behind a paywall, or automate the process so heavily that you lose the personal connection that makes cross-promotion actually work. CrossLetter gives you visibility and gets out of the way. That's it. That's the product.
CrossLetter's answer
Newsletter creators and independent publishers looking to grow through partnerships rather than paid ads. That includes solo creators running niche newsletters, media brands exploring sponsorship channels, and marketers who understand that reaching someone else's engaged audience is worth more than buying clicks from a cold one.
CrossLetter's answer
It came from lived frustration. The founder โ Des Brown โ both runs newsletters and keeps running into the same problem: finding cross-promotion partners was scattered, manual, and unnecessarily difficult. So they built the tool they wished existed. Nothing more complicated than that.
CrossLetter's answer
CrossLetter is free, so "customers" isn't quite the right framing โ but the platform hosts a growing directory of newsletters across niches like marketing, tech, business, creator economy, and personal development. The value isn't in big names โ it's in the quality of the matches people find. Users like AI Central, Presidential Summary and others with more than half a million+ subscribers already trust CrossLetter for their cross-promotion and sponsorship growth
