How it works
Tell us about your newsletter — your niche, your subscriber count, and what makes your writing special. Takes 30 seconds.
Our algorithm pairs you with a writer in the same or adjacent niche with a similar audience size — ensuring fair, balanced swaps.
Exchange cross-promotion emails with your match. You recommend them, they recommend you. New subscribers flow in both directions.
Every niche welcome
Whether you write about sourdough starters or startup strategy, there's a perfect swap partner waiting for you.
Writer love
Finally, a way to grow that doesn't feel icky. I got matched with a writer I genuinely admire and we both gained 120+ subscribers.
Cross-promotion always felt awkward to ask for. LetterSwap removes the cold-outreach cringe. It just works.
I was stuck at 800 subscribers for months. Two swaps later, I'm at 1,200 — and these are real, engaged readers.
