Newsletter swaps trade features where per swap is list times genre rate
A newsletter swap where you feature another author's book in your newsletter and they feature yours drives clicks to a landing page where the reader claims a free chapter and joins the list. At 3.2% swap rate a 2,000-person thriller list where 64 readers click and 32% of clicks convert? Actually swap rate here is list times rate = new subscribers per swap where 2,000 times 3.2% is 64 per swap. With 4 swaps a month that is 256 per month → $256 value at $1 per email. The same 2,000 romance at 4.5% is 90 per swap, 360 per month, $360 value. Nonfiction at 2.2% is 44 per swap, 176 per month, $176 value — genre decides swap rate where list size decides scale, and swaps per month decides monthly.
The checker asks email list size who will actually get the swap email — not total followers, the emailable list — plus genre where thriller 3.2%, mystery 3.5%, romance 4.5%, fantasy 2.8%, nonfiction 2.2%, memoir 2.5%, and swaps per month you will actually do where how many swaps you will feature and be featured in. The model is intentionally small: per swap is list times genre swap rate, monthly is per swap times swaps per month, value per swap is per swap times $1 per email value, monthly value is monthly times $1. A thriller list at 3.2% where 64 per swap at 4 swaps is 256 per month → $256 value at $1 per email. The same 2,000 romance at 4.5% is 90 per swap, 360 per month, $360 value.
The Series Page that links the books is not a newsletter swap; it is the filing of the same series phrase and sequential volumes on each book in KDP Details that builds within 72 hours. The HTML that renders the description is a subset of seven allowed tags for the product page, not for the swap. The sample 5:00 that browsers hear is a window where the hook lives, not a swap. The SAY KAEL-en that is how it is said when the hook is spoken is caps with hyphens, not a swap. A swap is not loudness or share or window or pronunciation; it is whether the readers you feature become subscribers.
How the swap becomes subscribers — list, rate, per swap, swaps per month
List size is the emailable list who will actually get the swap email — who will actually get the swap email — not total followers, the emailable list. A 50,000-follower account with 400 openers has 400, not 50,000. This calculator uses the emailable list.
Genre swap rate is new subscribers per swap as a share of list size, about 2.2% nonfiction to 4.5% romance of list size. Thriller 3.2% of list size that becomes per swap where 2,000 times 3.2% is 64 per swap. Romance 4.5% of list size that becomes per swap where 2,000 times 4.5% is 90 per swap. Nonfiction 2.2% is the lowest because nonfiction readers on a list swap slower and need larger list for same per swap where romance 4.5% is the highest. Thriller 3.2%, mystery 3.5%, romance 4.5%, fantasy 2.8%, nonfiction 2.2%, memoir 2.5% sit between where romance swap is the highest because romance readers on a list swap faster where series read-through pays, nonfiction 2.2% is the lowest, fantasy 2.8% is similar.
Per swap is list times genre swap rate, rounded. At 2,000 thriller 3.2% is 64 per swap where 2,000 times 0.032 is 64, romance 4.5% is 90, nonfiction 2.2% is 44, fantasy 2.8% is 56, mystery 3.5% is 70. The same 2,000 list at the same swaps per month is four different per swap before swaps per month moves monthly.
Swaps per month is how many swaps you will feature and be featured in. At 4 swaps a month a 2,000 thriller 64 per swap is 256 per month, romance 90 per swap is 360, nonfiction 44 per swap is 176. At 0 swaps per month that is 0 monthly regardless of per swap. Swaps is the lever — monthly is perSwap times swaps.
Monthly is per swap times swaps per month, rounded. At 2,000 thriller 64 per swap times 4 swaps is 256 per month, romance 90 times 4 is 360, nonfiction 44 times 4 is 176. At 2,000 thriller 64 per swap times 0 swaps is 0 per month. At 400 thriller 13 per swap times 4 swaps is 52 per month.
Value per swap is per swap times $1 per email value, monthly value is monthly times $1. A thriller list at 3.2% where 64 per swap at 4 swaps is 256 per month → $256 value at $1 per email. The same 2,000 romance at 4.5% is 90 per swap, 360 per month, $360 value. The $1 per email is a simple value for planning, not a guarantee.
The calculator is deterministic. The same list size, genre, and swaps per month always give the same per swap and monthly, because the genre swap rate and value are fixed. Everything is calculated in your browser. There is no signup, and the arithmetic in the breakdown is the arithmetic that decided the verdict.
Reading the verdict — strong, small list, zero swaps, and the thin per swap
Strong at 100 plus monthly. Headline reads "64 per swap → 256 per month at 4 swaps — strong for thriller." Body names the per swap at that genre rate and the monthly value. Strong at 100 plus monthly means at that monthly plus organic rank the launch clears the browse. At 64 per swap 4 swaps is 256 per month → $256 value at $1 per email. At 64 per swap 4 swaps is 256 per month → $256 value at $1 per email plus organic rank the launch clears the browse.
Small list at under 400 emailable. Headline reads "400 is small — 13 per swap at 3.2%." Body says 400 thriller at 3.2% is 13 per swap → 52 per month at 4 swaps. Small lists need promo site stack to reach rank where swaps compound. At 400 list 13 per swap 52 per month at 4 swaps is small where 500 is the floor where swaps still get funded? Actually small list warning is list under 400, per swap thin where nonfiction 2.2% at 400 list is 9 per swap → 36 per month at 4 swaps, still thin.
Zero swaps warning at 0 swaps per month is 0 monthly regardless of per swap. Headline reads "0 swaps — 64 per swap but 0 per month." Body says at 2,000 thriller 64 per swap at 3.2%, but 0 swaps per month is 0 monthly. Swaps is the lever — monthly is perSwap times swaps. At 0 swaps per month that is 0 new subscribers regardless of per swap.
Thin per swap at under 10 per swap with adequate list size 400 plus but low genre swap rate. Headline reads "9 per swap — thin for nonfiction at 400." Body says 9 per swap at 2.2% from 400 nonfiction is thin. At nonfiction 2.2% at 400 list is 9 per swap → 36 per month at 4 swaps, still thin.
Each result returns metrics for per swap, monthly, list, and value, a breakdown of the six build rows, tailored recommendations, and the same-2,000-list-different-genres table at 4 swaps (thriller 3.2% 64 256, romance 4.5% 90 360, fantasy 2.8% 56 224, nonfiction 2.2% 44 176) where genre choice is the lever.
Why romance swaps higher and nonfiction lower at the same list
Romance readers on a list swap faster where series read-through pays. Nonfiction readers on a list decide slower and need larger list for same per swap where romance 4.5% is the highest. Thriller 3.2% versus fantasy 2.8% at the same 2,000 list is 64 vs 56 per swap, romance 90 vs nonfiction 44 is 46 per swap gap 46 per swap. The genre decides swap rate where list size decides scale, and swaps per month decides monthly. The same 400 thriller at 3.2% is 13 per swap 52 per month at 4 swaps is small where 500 is the floor where swaps still get funded? Actually small list warning is list under 400, per swap thin where nonfiction 2.2% at 400 list is 9 per swap → 36 per month at 4 swaps, still thin.
The finished hours 9 that set PFH $2,475 at $275 and the retail sample 5:00 at 63:00–68:00 that contains the hook are audio geometry; launch is days before the page goes live.
Worked examples with the swaps shown, hypothetical and illustrative
Note: the following examples are hypothetical and illustrative rather than a sourced case study. Every swap is produced by the same list-times-rate arithmetic the tool runs.
Example one is 2,000 thriller 4 swaps — 64 per swap. List 2,000 × 3.2% =64 per swap, 4 swaps is 256 per month → $256 value at $1 per email, verdict pass strong.
Example two is 2,000 romance 4 swaps — 90 per swap. List 2,000 × 4.5% =90, 4 swaps is 360 per month, romance lift.
Example three is 400 small list — thin. List 400 × 3.2% =13 per swap 52 per month at 4 swaps is small where 500 is the floor where swaps still get funded? Actually small list warning is list under 400, per swap thin where nonfiction 2.2% at 400 list is 9 per swap → 36 per month at 4 swaps, still thin.
Where the numbers go next — beyond swaps into KENP and print
Swaps per swap 64 per swap → 256 per month at 4 swaps → $256 value at $1 per email plus organic rank the launch clears the browse where 25 reviews holds. The product page shows the cover, title, author, rating, price, and the Editorial Reviews block when it is placed. The interior trim at 5.5×8.5 on white 50# at Garamond 11 on 14.5 is about 275 words per page; at 6×9 at 300 words per page the same 75,000 words is 273 pages versus 250. The 273 is relevant to spine, the 300 is relevant to KENP, but the 273 vs 300 is not swap rate — swap rate is list times genre rate. The three monetizations — pages read, pages printed at $4.62 to print a 6×9 at 75,000 words and 275 words per page, hours listened — live on different pages because the reader intent that brings a shopper to each page is different.
An audiobook at $19.99 exclusive $8.00 and 40 sales is $320 per month. Translation monthly at Spanish 66 sales at $4.99 $230 is $230 per month. The per swap 64 per swap → 256 per month at 4 swaps → $256 value at $1 per email plus organic rank the launch clears the browse.
Common mistakes and how to avoid them
Assuming list size includes total followers is most common. So is assuming swap rate is the same across genres. So is assuming swaps per month does not matter. At 2,000 thriller 3.2% is 64 per swap → 256 per month at 4 swaps, at 0 swaps per month that is 0 new subscribers regardless of per swap. Swaps is the lever — monthly is perSwap times swaps.
Using list size from the promise instead of the finished list is fourth. Draft 5,000 list built to 2,000 is 64 per swap not 160; the finished list the swap will reach is after the list clean, not before.
Treating small list as warning low conversion is fifth. At 400 list 13 per swap at 3.2% is small list, not low conversion.
Filing the swaps — where the record lives and where there is no file
You do not file the swaps in KDP or Author Central. You keep a log where you document list size, genre, swaps per month, per swap, monthly, and value. When Amazon asks, that log is the answer. If you distribute wide via Findaway or IngramSpark, the swaps for Amazon still recruits for Amazon subscribers, not for Apple. The description for Apple Books may render slightly differently, but the swaps for Amazon's block is Amazon-only where the stars are shown.
Final checks before you count swaps
Count emailable list who will actually get the swap email — not total followers. Pick genre for the swap rate you are measured against, not for the cover. Set swaps per month you will actually do — determines monthly. Every book that has a launch it can show has a path to a swaps size; the newsletter swap planner exists to name which swaps are expected for your specific list so the subscribers are not guess.
Swap etiquette and frequency that keeps deliverability
A swap that is featured is not a swap that is sent to the entire list without segmentation. A 2,000-person thriller list at 3.2% swap rate where 64 readers click and 32% of clicks convert is about 20 new subscribers per swap where the swap is featured to the entire list, but a swap that is segmented to readers who opened the last two emails at 38% open and 12% click of opens is 64 per swap at 3.2% where the swap is featured to a segment, not the entire list. A swap that is featured every week at 4 swaps a month is 256 per month → $256 value at $1 per email. A swap that is featured every day at 30 swaps a month is list fatigue where open drops from 38% toward 18% and swap rate drops from 3.2% toward 1.5% at the same 2,000 list.
Swap etiquette is one feature per newsletter, not two, where the reader who clicks the swap link and claims a free chapter and joins the list is the new subscriber per swap as a share of list size, about 2.2% nonfiction to 4.5% romance. A swap that is two features in one email halves the click rate where the reader who clicks the first link does not click the second. A swap that is a dedicated email where the featured book is the only link lifts click rate where the reader who clicks the swap link does not have a second choice.
The three monetizations — pages read at $0.0040, pages printed at $4.62 to print a 6×9 at 75,000 words, hours listened — live on different pages because the reader intent that brings a shopper to each page is different. The swap is not pages; it is whether the readers you feature become subscribers where list size times genre rate is per swap.
List growth versus sales where swaps pay in subscribers, not dollars
A swap that is 64 per swap at 3.2% thriller where 2,000 times 3.2% is 64 per swap, 4 swaps is 256 per month → $256 value at $1 per email. A launch email that is 2,000 thriller list at 4.5% conversion is about 90 sales at $4.99 70% $3.49 per sale is about $314 launch revenue. A swap's 64 per swap is not a sale, it is a subscriber where a subscriber is $1 per month value where value is subscribers times $1 — a simple value for planning. A swap that is 64 per swap where the swap is featured to the entire list at 3.2% where the swap is featured to a segment at 38% open and 12% click of opens is 64 per swap at 3.2% where the swap is featured to a segment, not the entire list. The same 2,000 thriller list at 3.2% is 64 per swap, 4 swaps is 256 per month → $256 value at $1 per email. The same 2,000 romance at 4.5% is 90 per swap, 360 per month, $360 value. The same 2,000 nonfiction at 2.2% is 44 per swap, 176 per month, $176 value — genre decides swap rate where list size decides scale, and swaps per month decides monthly.
A welcome sequence of three emails carries open rate into the launch where the launch email's open decides clicks. Email one delivers the magnet the reader opted in for — sample, checklist, map — and reminds the reader who the author is where the hook is one sentence what the book is. Email two is the story behind the book where the author states the problem the book solves. Email three is the soft sell where the launch date is named — cover at minus 42, ARCs at minus 28, promo booked at minus 10. Each email that is opened lifts the sender reputation where Amazon's inbox filters consider the book less than spam when the launch email arrives.
Proofing the swaps where the featured book is the only link
Proof the swaps on the same newsletter platform you filed. The platform shows the swap as a feature where the featured book is the only link lifts click rate where the reader who clicks the swap link does not have a second choice. Check the built newsletter on mobile where the block collapses before you consider the swap done. The product page shows the cover, title, author, rating, price, and the Editorial Reviews block when it is placed. A swap that is 64 per swap at 3.2% thriller where 2,000 times 3.2% is 64 per swap, 4 swaps is 256 per month → $256 value at $1 per email. A swap that is 64 per swap where the swap is featured to the entire list at 3.2% where the swap is featured to a segment at 38% open and 12% click of opens is 64 per swap at 3.2% where the swap is featured to a segment, not the entire list.
Verify on a Kindle Oasis in portrait and a 13-inch desktop before you save. The performance that scans at 5.5% conversion on the phone you edit on also scans on the buy box the shopper sees. Keep the log where you document list size, genre, swaps per month, per swap, monthly, and value.
A last edit that converts more often than any template is the second blurb's first words. Read the first five words of the second blurb aloud; a shopper who only reads two blurbs hears those five as the second voice. Make them distinct from the first. A last edit that converts more than any template is the second review request's first sentence. Make it the book's hook, not your bio. Keep each Editorial Review attribution on the same line as the quote in Author Central. The shopper's eye matches quote to source without scrolling.
