Half the indie authors at any given virtual conference have never done one. Some of the people selling $500 email marketing courses haven’t either. Newsletter swaps – two authors, one email each, recommending each other’s books on the same day – remain one of the most ignored tactics in self-publishing.
Worth sitting with for a second.
What Is a Newsletter Swap, Exactly?
Two authors. One email each. Same day.
You write a short recommendation for their book and send it to your list. They do the same for you. No platform takes a cut. No algorithm decides who sees it. The reader gets a book recommendation from an author they already trust enough to let into their inbox – which is a different class of attention than paid advertising buys.
That’s the engine. One author’s credibility, loaned for a moment, on behalf of another.
You Need a List First. Even a Small One.
You can’t swap nothing. A newsletter with 80 subscribers and a 45% open rate is more attractive to a swap partner than 2,000 addresses scraped from a giveaway that nobody opens. Engagement is the asset. Headcount is the vanity number.
If you’re starting at zero, the fastest path to your first 200 subscribers is group promotions on BookFunnel or StoryOrigin – coordinated events where a dozen or more authors each contribute a free book to a single landing page, then all promote it at once. You bring a small audience and leave with exposure to a dozen others’. Do a few of these, build a habit of actually emailing your list, and you’ll be ready to swap inside a month.
Before Your First Swap, You Need These Things
A reader magnet: a free short story, prequel novella, or bonus scene that new subscribers receive in exchange for their email. It needs a real cover. Readers judge a free book the same way they judge a paid one. “It’s free” is not a design brief.
A newsletter you’re actively sending. Swap partners will ask for an archive link – a public view of a past email you’ve sent. If you have nothing to show, you have nothing to offer.
A book that’s easy to try. Something free, in Kindle Unlimited, or priced at 99 cents. The lower the barrier, the more of those incoming clicks turn into readers who finish the thing.
How to Run Swaps on StoryOrigin
Start here if you’re choosing between the two platforms. StoryOrigin publishes every author’s stats: open rates, click rates, list size, and a full history of clicks they’ve actually sent in previous swaps. That last column is the one that separates the serious from the deadweight.
It shows you who sends the emails they agree to and who doesn’t.
Here’s how to run your first swap:
Create a free account at storyoriginapp.com and add your book.
Go to the Newsletter Swaps tab and browse requests in your genre.
Before accepting anything, check the author’s stats. An open rate above 25% is healthy. You want at least a handful of clicks in their historical record – proof they write the emails they agree to write.
Send a swap request. Name the book, your preferred send date, and what you’re offering in return.
Once confirmed, exchange a cover image, a 2–3 sentence hook, and the platform’s generated tracking link. Not a direct Amazon URL. The tracking link is what lets both parties confirm the other person actually sent the email.
Feature their book on the agreed date. Submit your archive link afterward as proof of delivery.
How to Run Swaps on BookFunnel
BookFunnel calls the feature Author Swaps, located under Promotions in your dashboard. You’ll need at minimum a Mid-List plan ($100/year) to access it and connect your email list.
The mechanics are identical – exchange assets, use tracking links, confirm with an archive link – but BookFunnel publishes no author stats. You’re working on reputation and community word-of-mouth. A lot of swaps on BookFunnel get arranged in the community’s Facebook group before anyone touches the platform.
BookFunnel’s edge is reader onboarding. When someone can’t get a file onto their Kindle, BookFunnel’s help desk handles the call. That doesn’t affect the swap mechanics, but it affects how many of those new subscribers actually read the book they downloaded.
Who to Swap With, and Who to Skip
Treating list size as the primary filter is the quickest way to waste a month. A 400-person paranormal romance list where readers open every email will send you more real subscribers than a 5,000-person general fiction list where 80% haven’t clicked anything in four months.
Genre specificity is the first filter. Dark fantasy readers and cozy fantasy readers are not the same people with the same tastes who happen to have picked different subgenres by accident. A grimdark author and a cozy mystery author swapping newsletters are two people quietly degrading each other’s open rates.
On StoryOrigin, pull up the swap history before accepting. Zero historical clicks across two years on the platform is a pattern, not an oversight. It means they take swaps and don’t send them – or send something so buried it might as well not exist.
On BookFunnel, ask for an archive link and read it. Notice how they feature recommendations: a buried line at the bottom with no cover image versus a dedicated callout with a hook and the book’s actual premise. One of those converts. The other exists so the sender can claim they fulfilled the agreement.
One thing that should end the conversation before it starts: anyone who messages you asking for a swap before they’ve said a word about your book.
What to Actually Write
A cover image. A one-line hook naming the premise – not “this incredible story,” not “a must-read.” Your readers can smell performance. One sentence in your own voice: something like “I read this last week and it’s scratching the same itch as [your series].” Then the link.
That’s a feature. It takes six minutes.
What it isn’t: a paragraph at the bottom of your newsletter, below the main content, in a smaller font, with no image, that reads “Also check out my friend’s book!” Nobody clicks that. Your swap partner knows nobody clicked that when they look at the stats afterward.
What to Expect
Four to 50 new subscribers per swap. The range depends on genre fit and how engaged both lists are. That ceiling sounds low until you run 6 swaps a month consistently and the subscribers start to compound.
These readers arrived through an endorsement, which means they’re already warmer than someone who clicked a Facebook ad. They cost nothing beyond the time to write a short recommendation. The ones who stay tend to buy.
The first swap is the one with the highest friction – no track record, no archive links to show, no sense of which subgenres actually overlap with your readership. After that first one, all three of those problems are solved.
Send a request this week. The answer might be no.

For post-apocalyptic genre, I wish I started with Bookfunnel instead of StoryOrigin. More PA authors there
