The single biggest lever on whether a reader gives you their email address is not your landing page design — it’s whether the bonus you’re offering feels specific and worth having. “Join my newsletter” describes a benefit to you. A genre-relevant bonus describes a benefit to them. Here are fifteen ideas that actually convert, organized by category.

What Makes a Reader Magnet Work

Before the list, three quick principles that apply across every category below:

1. Relevance beats production value. A rough one-page checklist tied directly to your book will outperform a polished but generic 20-page guide about something adjacent.
2. Low effort to consume beats high effort. A reader who just finished your book wants something they can use in the next five minutes, not another long read.
3. It should point back to more of your work. A deleted scene from the book they just read is more effective than an unrelated short story from a different series, because it deepens the exact relationship they already have.

Fiction Reader Magnets

1. Deleted or alternate scene. A scene cut during editing, or the same pivotal scene rewritten from a different character’s point of view. Low effort to produce if you kept your drafts.

2. Prequel short story. A short piece set before the events of the book, especially effective for series — it works as both a bonus and a soft pitch for book two.

3. Character backstory. A short piece focused on a side character readers were curious about. Works well for ensemble casts.

4. Bonus epilogue. An extra scene showing where the characters end up, useful for standalone novels and series finales alike.

5. World-building guide or map. Especially effective for fantasy and sci-fi — a character glossary, timeline, or map readers can reference.

6. Early access to the next book’s first chapter. Directly converts current readers into pre-launch anticipation for your next release.

7. Discount code for book two. Simple, direct, and effective for series where the reader’s next step is obvious.

Nonfiction Reader Magnets

8. Companion checklist or worksheet. Tied directly to a framework or process described in the book — this is consistently one of the highest-converting nonfiction magnets because it’s immediately actionable.

9. Templates referenced in the book. If your book describes a process (a budget, a content calendar, a meal plan), the fillable template itself is a natural bonus.

10. Resource pack. A curated list of tools, links, or further reading related to your topic, saving the reader research time.

11. Extended or bonus chapter. Content that didn’t make the final cut of the book, offered as a standalone bonus.

12. Video or audio walkthrough. A short recording expanding on one concept from the book — useful if you’re comfortable on camera or with audio.

13. Case study or example pack. Concrete examples applying the book’s method, especially valuable in business and self-help categories.

Cross-Genre Magnets

14. A short story or piece from a different series. Works as a “if you liked this, try this” bridge into the rest of your catalog — best used once a reader has already opted in for a book-specific bonus, not as the first offer.

15. A signed digital certificate or personal note for younger or children’s book audiences. Pairs well with printable activity pages as a bonus for the parent, who is the one actually signing up.

How to Pick One for Your Book

If you only have time to build one, default to whichever idea took the least additional writing or design work relative to your existing manuscript — a deleted scene you already have in an old draft, or a checklist that summarizes a framework you already wrote out in full. The goal on your first attempt is to get something live and tested, not to build the most elaborate bonus possible. You can always add a second or third bonus once the basic funnel is working.

Turning the Idea Into a Live Page

Once you’ve picked a bonus, the next steps are building a landing page, generating a print-friendly link, and placing the call-to-action correctly inside your manuscript — we cover that full process in our guide to building an email list from your KDP books, including exactly where the CTA should sit for the best conversion, covered in more depth in our back matter link strategy guide.

Tools like AI Reader Rocket include a reward-idea library covering many of the categories above, which can help if you’re staring at a blank page trying to decide — see our full review for how that feature works in practice.

The Takeaway

A reader magnet doesn’t need to be elaborate. It needs to be specific to the book the reader just finished, quick to consume, and easy to deliver. Pick one from the list above that you can realistically produce this week, and you’ll be ahead of the majority of KDP authors who never get past the “what should I even offer” stage.
