Book Promotion Sites: Free and Paid Ebook Deal Sites Compared (2026)

A promotion site sends your deal to readers who signed up for bargains in your genre, so a free or discounted ebook can be sent to thousands of readers in a day. The catch is that each site has its own rules, from minimum reviews to how far ahead you must book, and fees that change with genre and price. This guide lists the main sites by type, with the rules and fees each one published in October 2026, so you can pick the right ones for your book. If you’d rather have someone plan this for you, our book promotion services include deal sites in a launch plan.

How book promotion sites work

You choose a date and set your ebook to a deal price, usually free or $0.99 to $2.99, on the stores the site links to. You book a slot and pay the site, and its editors check that your book fits its rules. On the day, your book appears in an email, and often on the site and social media, sent to readers who chose your genre. Readers click through to the store and buy or download the book there.

The deal sites below charge a flat fee per listing, set by genre and deal price, with one exception: BookRaid charges per click. List builders such as BookFunnel and StoryOrigin charge a monthly or yearly plan. None of them can promise sales, and a site that does is a red flag.

What you need before you book

• A deal price, set on time. Sites take free books or deal prices, and several require at least 50% off. Set the price early: eReader News Today wants it live by 6am Eastern on the day, and Robin Reads recommends changing it 24 hours ahead.
• Reviews, for some sites. Several general sites have no minimum, but others ask for 5 or 10 reviews with a good average on Amazon US. If you have few, start with the sites that don’t require them; see how to get book reviews.
• A cover that fits the genre and a clean book page. Editors turn down books that don’t look ready.
• The right store setup. If your ebook is in KDP Select, it’s sold only on Amazon, and you have two ways to discount it: up to 5 free days per 90-day term, or, once the book has been enrolled for 30 days and is listed at $2.99 to $24.99, a Kindle Countdown Deal on Amazon.com and Amazon.co.uk, where you keep the 70% royalty even below $2.99 if your book is on the 70% option (see KDP Select free days). You can’t use both in the same term. If you’re wide, you can set the deal price on every store.
• A plan for the full price. On Amazon.com, the 70% royalty needs a list price of $2.99 to $12.99 (since July 2026); a $0.99 price outside a Countdown Deal earns 35%. A deal usually pays off best when the book is the first in a series or leads to your newsletter.

Book well ahead of your book launch checklist dates or your sale week, since some sites need two weeks’ notice.

Promotion sites by type

Every rule and fee below comes from each site’s own pages in October 2026. Sites change their prices and rules often, so check before you book. Fees are for a standard listing; premium slots, such as a Free Book of the Day, cost more. Subscriber numbers are the sites’ own claims.

Free-book promotion sites

These sites focus on free ebooks, which suit a first-in-series book, a KDP Select free run, or a permanently free book.

• Freebooksy: free ebooks in many genres, sent to up to 500,000 readers, it says. The book must be free in the US all day (free only in Kindle+, formerly Kindle Unlimited, doesn’t count), over 50 pages, and promoted no more than once a month. No minimum reviews. Fee: $25 to $120 by genre, shown when you book; mystery was $100 and horror $40.
• The Fussy Librarian: free and bargain ebooks; claims 570,000 subscribers for its free list. No minimum reviews, but it asks for a quality cover; preorders and box sets are accepted. Fee for a free book: $15 to $79 by genre.
• eReader News Today: free and discounted ebooks in 25 genres. Needs at least 125 pages (children’s, non-fiction and cookbooks are exempt), a deal on Amazon.com, no minimum reviews, and booking at least two weeks ahead; no erotica. Fee: $40 to $140 by genre and price; a free fantasy book was $40, a $2.99 romance $140.
• Robin Reads: free and $0.99 books, hand-picked, with no children’s list; claims over 194,000 members and says it accepts fewer than 10% of submissions. No minimum reviews, though reviews count; the same book can run once every 90 days. Fee: $40 to $85 a day.

Discounted-deal promotion sites

These sites take paid deals, usually $0.99 to $2.99, and some take free books too.

• Bargain Booksy: discounted ebooks only, no free books. Over 50 pages, once a month per book, no minimum reviews. Its pages give the price range as $0.99 to $5, and its booking page says below $4.99, so check the cap when you book. Fee: $20 to $90 by genre, shown when you book.
• The Fussy Librarian (bargain list): books at $5.99 or less. Fee: $10 to $22 by genre.
• BookRaid: free books or discounts of at least 50%. Needs 120 pages for fiction, 80 for non-fiction and 20 for children’s books, and the book must be on Amazon; no minimum reviews and no AI-written books. You pay per click: $0.15 for a free book up to $0.60 at $2.99, capped at $60.
• Booksends: deals under $3 and at least 50% off, or free, on Amazon US. Needs at least 5 reviews with a high average; book 3 to 30 days ahead. Fee: $10 to $120 by genre and price; a $0.99 romance was $60. Its Free Book of the Day slot was $125.
• eReaderIQ Daily Deals: Kindle deals, free or at least 50% off and rarely above $1.99; claims over 47,000 readers. Needs at least 5 reviews with a high average, and the same book can run once every 90 days. Fee: $5 to $40 by genre and price.

Genre specialists

Smaller lists, but every reader chose your genre. Three of the four ask for reviews.

• Romance, Red Feather Romance: free and paid romance, no discount required; claims over 120,000 readers. Fee: $85 to $135, shown when you book. (Its promo page talks about steamy romance, while its booking page also lists sweet romance.)
• Romance, Red Roses Romance: romance only, standalone or first in a series, free or at least 50% off. Should have at least 10 reviews averaging 3.5 stars on Amazon US. Fee: $25 to $40.
• Science fiction and fantasy, Book Barbarian: free or at least 50% off, standalone or first in a series preferred; claims over 60,000 subscribers. Should have at least 10 Amazon US reviews averaging 3.5 stars (a new release can qualify if an earlier book has more than 50). Fee: $40 to $60.
• Mystery and thriller, Book Adrenaline: claims over 36,000 subscribers. Should have at least 10 reviews averaging 3.5 stars on Amazon.com, with the same new-release exception. Fee: $20 to $30.

Series and box sets

If you have a series, promote the first book; readers who like it may go on to buy the rest. Freebooksy also sells a series promotion ($65 to $245 by genre; book 1 must be free, with more than ten reviews of 4 stars or better, and the series needs at least 3 books), Red Feather Romance a series slot ($185), and The Fussy Librarian accepts box sets.

Reader list builders

These don’t need a deal. You join a group promotion with other authors in your genre, usually offering a free book or sample in return for newsletter signups, and everyone shares the promotion with their readers.

• BookFunnel: delivers your free book and runs group promotions set up by other authors, each with its own rules. Plans cost $30 a year (First-Time Author), $200 a year or $20 a month (Mid-List) and $300 a year or $30 a month (Bestseller); collecting emails on your landing page needs Mid-List or above.
• StoryOrigin: group promotions and newsletter swaps. The free plan doesn’t include them; the Standard plan does, at $10 a month or $100 a year.

BookBub

BookBub claims over 15 million readers for its deals email, but its editors choose which books to feature, and Featured Deal fees ran from $122 to over $4,000 in October 2026, by genre, price and region. It’s covered in its own guide: see what BookBub requires.

How to stack promotions

Stacking means booking several sites over a few days of the same deal, rather than one big day.

1. Pick a deal window of 3 to 5 days, and set the price the day before it starts.
2. Book one site per day, so each day gets fresh readers. If one list is much bigger than the others, consider putting it later in the window, when earlier days may already have lifted the book’s rank.
3. Check each site’s rules against your dates: lead times, how long since your last promotion with them, and whether they want a free or paid deal.
4. Keep the price steady for the whole window (for a Countdown Deal, use a single price step), and leave the list price unchanged for 30 days before and 14 days after a Countdown Deal.
5. Tell your newsletter and readers on the first day.

Start small with a site or two, see what happens, and add more next time.

How to measure results

Write down each site, its fee and its day. Then compare, day by day:

• Sales and free downloads in your KDP reports and other stores’ dashboards.
• Pages read in Kindle+ (formerly Kindle Unlimited), if the book is in KDP Select.
• Sales of your other books in the weeks after, especially later books in a series.
• New newsletter signups, if your book links to a signup page.

A site that sends few downloads on its day may still be worth it for a free first-in-series book. Add the results to your book marketing plan and repeat what pays for itself.

Red flags

• Promised sales, downloads or rankings. No site controls what readers do.
• Reviews as part of the deal. Amazon doesn’t allow reviews given in exchange for any compensation, including payment or a free copy given on condition of a review, so avoid any promotion that bundles reviews in.
• No audience details. A real site says what it sends, to whom and in which genres.
• No rules page. If a site doesn’t publish its requirements, you can’t tell whether your book fits.

When to get help

If you’d rather focus on writing, our 8-week launch plan ($749) dates every task back from your launch day and includes early copies listed with a reader platform, pre-orders, newsletter swaps, a BookBub Featured Deal application and 4 strategy calls. Promotion and deal fees are paid by you, directly to each site. Ads optional, in your name: we set up ad accounts for $299 per platform and manage them for $499 a month per platform, with a 3-month minimum, and ad spend is paid by you directly. We never promise sales, reviews or rankings.

Book promotion site questions

Are free book promotion sites worth it?

They can be, when the free book leads somewhere: the first book in a series, or a book that sends readers to your newsletter. A free day earns nothing on the day, so the value comes from later sales, reviews and signups. For a standalone book with nothing else to buy, a discounted deal can make more sense.

Do you need reviews before booking a promotion?

Not for every site. Freebooksy, Bargain Booksy, The Fussy Librarian, eReader News Today, Robin Reads and BookRaid set no minimum in October 2026, though some weigh reviews when they choose. Booksends and eReaderIQ ask for 5, and three of the four genre sites for 10 averaging 3.5 stars.

Can you promote a KDP Select book for free?

Yes. KDP Select gives you up to 5 free days per 90-day term, which you can run together or split up, and many free-book sites accept them. You earn no royalties on free downloads. You can’t also run a Countdown Deal in the same term.

How far ahead should you book?

Two to four weeks ahead fits every site in this guide that publishes a lead time. eReader News Today asks for at least two weeks, Booksends for 3 to 30 days, and Robin Reads opens its calendar up to two months ahead. Popular dates fill first, so book early for a launch.

Do promotion sites work for paperbacks?

No. These sites promote ebook deals. To promote a paperback, use ads, events or your newsletter, or discount the ebook so new readers find the series.
