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.

Possible disadvantages of PythonAnywhere

  • Limited Customization
    The pre-configured environment limits customization options, which may be a drawback for more advanced users who require specific configurations or installations.
  • Free Tier Limitations
    The free tier has significant limitations, including restricted CPU time and storage space, which can hinder more demanding applications.
  • Performance
    Shared plans might experience slower performance during peak times due to the shared nature of the infrastructure.
  • Lack of Root Access
    Users do not have root access to the underlying system, which can be a limitation for deploying certain types of applications or custom services.
  • Support Limitations
    While it offers community support and documentation, the level of professional support might not meet the needs of all users, especially those on lower-tier plans.
  • Limited Language Support
    Primarily focused on Python, which may not suit all projects, especially those requiring multi-language support.
  • Resource Constraints
    Lower-tier plans have stringent resource limits (CPU, RAM, storage), which can be restrictive for resource-intensive applications.

Analysis of CrossLetter

Overall verdict

  • I don't have verified, up-to-date information about CrossLetter (crossletter.com) to confidently assess its quality, features, pricing, or user satisfaction. Any specific claims about this service would be speculative rather than based on confirmed data.

Why this product is good

  • Unable to verify core features or functionality without direct, current information

  • Cannot validate pricing, reliability, or customer support quality
  • Recommend checking the website directly, reading recent user reviews on trusted platforms, and testing any free trial before committing

Questions & Answers

As answered by people managing PythonAnywhere and CrossLetter.

Which are the primary technologies used for building your product?

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

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your 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.

What's the story behind your product?

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.

Who are some of the biggest customers of your product?

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

  • [Offer] I need someone to set up a webhook in my WordPress site and a Python server with listener + bot
    The website is already built. Each comment will have a reddit post URL, and the bot should leave a comment on that URL. We can use pythonanywhere.com for this to make it easiest. Source: about 3 years ago
  • Flask and web hosting
    If you are learning, use pythonanywhere.com as they specialize in python, and make setup easy. Only $5 a month. Start with a barebones flask app, get it to run, then follow a tutorial. Actually better to build the app locally, easier to test with IDE like Pycharm. Then upload to the net. Source: about 3 years ago
  • Redirecting client to my server via a external server
    Hello, I have a Minecraft server running on a Rpi with Paper. It works great and I use it to play with some of my friends. However, the server's public IP address often changes, meaning that I have to give my friends the new IP address daily. Being a programmer, I feel this could be automated. I don't want to buy a domain, so I want to try and setup a system where the server sends Its IP to my PythonAnywhere... Source: over 3 years ago
  • Question Gallery WebApp Django or Flask?
    Hosting wise, I would reccomend pythonanywhere.com, combined with either https://imagekit.io or https://cloudinary.com. Source: over 3 years ago
  • Cheap Heroku alternative for PHP MySQL app
    So what is the best alternative? I have one Plotly Dash app on pythonanywhere.com where I spend 6 bucks a month so I don't want to spend anymore than 5 dollars per month on the PHP + MySQL. Source: over 3 years ago
