A BookBub Featured Deal is the single most powerful promotional tool available to authors. One email from BookBub can generate thousands of downloads or sales in 24 hours, catapult your book up the Amazon bestseller rankings, and create a read-through wave across your entire backlist.
The challenge is getting accepted. BookBub’s acceptance rate is estimated at 10 to 20 percent. This guide covers exactly how the process works, what increases your chances, and what to do if you do not get accepted.
What BookBub is and why it matters
BookBub is an email recommendation service with over 15 million subscribers who have opted in to receive daily book deals in their preferred genres. When BookBub features your book, they email it to the segment of their list that reads your genre.
The scale is what makes BookBub different from every other promotion service. A romance Featured Deal might reach 2 to 5 million subscribers. A mystery deal might reach 1 to 3 million. No other promotion platform comes close to this reach.
What a Featured Deal can deliver
Results vary by genre, pricing, and book quality, but typical outcomes for a Featured Deal include:
- Free book promotion: 10,000 to 50,000+ downloads in 24-48 hours
- $0.99 book promotion: 500 to 5,000+ sales in 24-48 hours
- Amazon ranking: Frequently pushes books into the top 100 overall on Amazon
- Read-through: If you have a series, the spike in book one readers drives sales of subsequent books for days or weeks after the promotion
According to data shared by Written Word Media, authors with series consistently report that the read-through revenue from a BookBub deal exceeds the direct revenue from the promoted book by a factor of 2x to 5x.
How Featured Deals work
The application process
You submit your book through BookBub’s partner dashboard. There is no cost to apply. You fill out:
- Book title and retailer links
- Regular price and deal price
- Preferred date range for the promotion
- Genre category
BookBub’s editorial team reviews submissions against their quality standards and reader preferences. They notify you 7 to 10 days before your deal date if accepted.
What you pay
BookBub charges a fee to run a Featured Deal. The fee depends on your genre and deal price. Typical costs:
| Genre | Free Book | $0.99 Book | $1.99-$2.99 Book |
|---|---|---|---|
| Romance | $240-$408 | $408-$600 | $600-$840 |
| Mystery/Thriller | $180-$312 | $312-$456 | $456-$600 |
| Fantasy/Sci-Fi | $156-$264 | $264-$384 | $384-$504 |
| Nonfiction | $96-$168 | $168-$240 | $240-$336 |
These fees are an investment, not a cost. For authors with series, a single BookBub deal frequently generates 3x to 10x return on investment when read-through is factored in.
Your responsibilities
When accepted, you must:
- Drop your book to the agreed-upon price on the deal date (on all retailers)
- Keep it at that price for the duration of the promotion (typically 1-3 days)
- Ensure the book is available and purchasable on the featured retailers
How to increase your acceptance chances
Have a professional cover
BookBub’s editorial team evaluates covers as part of their review. Your cover needs to look like it belongs on a traditionally published bestseller in your genre. If your cover is amateurish, your submission will be rejected regardless of everything else.
Study the covers of books that have been featured in your genre. Match that quality level.
Accumulate reviews
BookBub does not publish a minimum review requirement, but data from accepted authors suggests you need at least 15 to 25 reviews on Amazon, with an average rating of 4.0 or higher. More reviews improve your chances.
Build your review count through a book launch team, organic readers, and Amazon review strategies. Do not rush the BookBub submission until your social proof is strong enough.
Choose the right price point
Free and $0.99 deals have higher acceptance rates than higher-priced deals because they perform better for BookBub’s subscribers. If this is your first submission, apply with a free or $0.99 deal.
For series authors, making book one free is a proven strategy: the free downloads generate massive read-through to full-priced later books.
Submit for the right genre
BookBub allows you to select your genre category when submitting. Choose the most accurate genre, not the broadest one. A “cozy mystery” submission competes against fewer applicants than a generic “mystery/thriller” submission.
Give a wide date range
When specifying your preferred dates, offer the widest range possible (at least 30 days). BookBub’s editorial calendar fills at different rates for different genres. Flexibility increases your chances of being slotted in.
Wait between resubmissions
If rejected, wait at least 30 days before resubmitting the same book. Use that time to gain more reviews, improve your cover, or try a different price point. BookBub does not penalize resubmissions, and many authors report being accepted on their second or third attempt.
Apply with a strong retailer presence
BookBub prefers books available on multiple retailers (Amazon, Apple, Kobo, B&N, Google Play). If your book is in KDP Select, you can still apply (Amazon-only deals exist), but wider availability improves your submission profile.
Maximizing your BookBub deal results
Stack promotions
Do not rely on BookBub alone for your deal day. Coordinate with:
- Your email list. Email your subscribers about the deal on the same day. Newsletters amplify the BookBub effect.
- Amazon Ads. Increase your ad budget on the deal day. The surge in sales velocity improves your organic ranking, and ads capitalize on that momentum.
- Other promotional services. Submit to Freebooksy, Bargain Booksy, Robin Reads, and Written Word Media for the same date. Stacking multiple promotions on the same day creates a compounding visibility effect.
- Social media. Post about the deal across all platforms. Share the BookBub link, which lends additional credibility.
Have your series ready
The biggest financial return from a BookBub deal comes from read-through. If you promote book one but book two is not published yet, you lose the most valuable part of the promotion.
Ideally, promote book one when at least three or more books are available in the series. Every additional book multiplies the revenue from each new reader who enters through the deal.
Track your results
Monitor your sales dashboard throughout the deal day and for two weeks afterward. Track:
- Direct sales of the promoted book
- Sales of subsequent books in the series (read-through)
- KU page reads (if applicable)
- Email list signups (if your reader magnet is in the back matter)
- Amazon ranking changes
What to do if you are not accepted
Try again
BookBub rejection is normal. Many successful authors were rejected multiple times before being accepted. Each resubmission is fresh consideration.
Between submissions:
- Gain more reviews
- Improve your cover if it is below genre standard
- Try a different price point (free instead of $0.99)
- Try a different genre category if your book fits multiple
- Expand to wider distribution if you are Amazon-exclusive
Use alternative promotion services
While no single alternative matches BookBub’s reach, combining several services can produce meaningful results.
Written Word Media. Their Freebooksy and Bargain Booksy lists reach hundreds of thousands of genre readers. Strong results for romance, mystery, and fantasy. Pricing starts at $40 to $130 depending on genre and deal type.
Robin Reads. Growing email list with competitive pricing. Good results for a wide range of genres. Typical cost: $25 to $60.
eBookSoda. UK-based promotion service with a dedicated reader audience. Affordable pricing starting around $20.
BookGorilla. Amazon-focused promotion service. Their subscriber base actively watches for Kindle deals. Cost varies by genre.
Stacking strategy: Run Freebooksy + Robin Reads + BookGorilla on the same day for a combined reach that approaches a mid-tier BookBub deal at a fraction of the cost.
Use BookBub’s other features
Even without a Featured Deal, BookBub offers:
- BookBub Ads. A self-serve advertising platform where you bid on impressions shown to BookBub’s subscriber base. You can target readers by genre, author interest, and more. Available to all authors regardless of Featured Deal acceptance.
- New Release alerts. Claim your BookBub author profile and readers who follow you get notified when you publish a new book.
- Pre-order alerts. Similar to new release alerts, for pre-order availability.
Common mistakes to avoid
- Submitting with fewer than 15 reviews. Your acceptance chances are significantly lower without enough social proof. Build reviews first.
- Using an amateurish cover. BookBub’s team evaluates visual quality. A poor cover is an immediate rejection signal.
- Submitting for the wrong genre. If your book is a cozy mystery, do not submit it as a general thriller hoping for a bigger audience. Genre accuracy matters.
- Not dropping your price on time. If accepted, your book must be at the deal price before BookBub sends the email. Missing this window is catastrophic and may disqualify you from future deals.
- Wasting a deal on a standalone book. A BookBub deal on a standalone generates a spike and then nothing. A deal on book one of a series generates a spike plus weeks of read-through revenue. Prioritize series starters.
FAQ
How long does it take to hear back from BookBub?
You will receive an acceptance or rejection email 7 to 10 days before your earliest requested date. If your entire date range passes without acceptance, your submission was rejected. BookBub does not always send explicit rejection emails for all submissions.
Can I apply to BookBub with a book in KDP Select?
Yes. BookBub runs Amazon-only Featured Deals. Your acceptance rate may be slightly lower compared to books available on multiple platforms, but KDP Select books are regularly featured.
Is a BookBub Featured Deal worth it for a new author?
If you have at least one well-reviewed book with a professional cover, yes. Even for a standalone, the sales surge and ranking boost can establish your book’s visibility for weeks. For a series author, the ROI is even clearer. The promotional fee pays for itself through read-through in most cases.
