Reader Magnets: The Fastest Way to Build Your ARC List
A reader magnet turns browsers into email subscribers — and email subscribers into your most loyal Amazon reviewers.
What Is a Reader Magnet?
A reader magnet is a free piece of content — an ebook, short story, guide, or exclusive document — you give away in exchange for an email address. The key is that it must be something your ideal reader genuinely wants. Not a bribe. Not generic filler. A real piece of value that your target audience is actively looking for.
The reader magnet is the start of a relationship. It works best when positioned as: "Join my readers' group and get [X] free." That framing signals community and exclusivity, not a transactional email trade.
Once someone is on your list, they are no longer a stranger. They're a reader who chose you. That relationship — built through your welcome sequence and regular emails — is what turns a subscriber into an ARC reader, and an ARC reader into a consistent Amazon reviewer across every book you publish.
7 Reader Magnet Ideas That Actually Work
For fiction and non-fiction authors at any stage
Prequel Novella
Best for fictionThe most powerful fiction reader magnet. A short story set in your world, before your main book's events. Readers who love it are pre-sold on your series — they've already bought into your characters and world before they've spent a dollar.
Character Companion
Fantasy · Sci-fi · HistoricalA character sheet, map, or "behind the scenes" document for your fictional world. Makes subscribers feel like insiders with access to content that never made it into the published book. Great for world-building-heavy genres.
Deleted Scenes
Any genreContent that didn't make it into the final book. This positions your subscriber list as a VIP group — people who get more than regular readers. Easy to create if you have material in your drafts.
Short Story in Your Genre
FictionA standalone short story (5,000–20,000 words) that matches the tone and genre of your published books. Introduces new readers to your voice and style before they commit to a full novel.
Checklist or Cheat Sheet
Best for non-fictionA condensed practical tool — like "The 30-Day Writing Habit Tracker" or "7-Step Morning Routine for Creative Writers" — converts extremely well. Readers download it because it solves a specific problem they have right now.
First Chapter(s) Free
Non-fictionOffer the first 2–3 chapters of your book as a free download. Readers who download it have self-selected as interested — they're warm leads for your ARC list and far more likely to purchase the full book.
Bonus Epilogue or Extended Ending
Series authorsA bonus chapter from the perspective of a beloved secondary character. Existing readers and fans will sign up specifically to get it. This is the highest-converting reader magnet for authors with an established readership.
How to Deliver Your Reader Magnet
Create the File
Use Canva to design a cover, then format the content in Reedsy or Atticus. Export as a PDF or EPUB. Keep it clean and professional — first impressions matter.
Host It
BookFunnel is the industry standard for indie authors. It handles delivery, tracks downloads, and connects to your email service. StoryOrigin is a free alternative. Avoid emailing files directly — delivery rates drop and it creates support issues.
Set Up Your Welcome Sequence
MailerLite and Kit (formerly ConvertKit) are the most popular email tools with authors. Your welcome email should deliver the reader magnet, introduce yourself warmly, and include a soft invitation to join your ARC team.

Without a Reader Magnet
- ✗ No email list — every launch starts from zero
- ✗ Relying entirely on iWrity or social for reviews
- ✗ No warm audience for the next book
- ✗ Review count resets with each new title
With Reader Magnet + iWrity
- ✓ Email list grows between every launch
- ✓ iWrity fills the gap while your list is small
- ✓ Each launch bigger than the last
- ✓ Compounding review base across your backlist
What If You're Starting from Zero?
Reader magnets take time. Building a list of 500–1,000 engaged readers can take 6–18 months. If your next launch is in 4 weeks, you need reviews now — not a list that's barely started.
That's where iWrity fits. While your reader magnet builds your long-term list, iWrity connects your book with genre-matched readers immediately — so you can launch with reviews even before your email list is large enough to support it. Most authors use both: iWrity for immediate launch reviews, their own list for compounding reviews across every book.

How long should a reader magnet be?+
For fiction, a reader magnet should be 5,000–20,000 words — long enough to give readers a genuine taste of your voice and world. A prequel novella or standalone short story in that range works best. For non-fiction, a well-structured checklist or condensed guide can be as short as 1,000–3,000 words and still convert very well. Quality and relevance matter far more than length.
Can I use a reader magnet if I only have one book published?+
Absolutely. A reader magnet does not require a backlist. If you have one book, offer deleted scenes, a character companion, or a prequel short story set before your book's events. For non-fiction authors with a single title, a condensed version of your core framework or a related checklist works well. Your reader magnet simply needs to be something your ideal reader genuinely wants.
What's the best platform to host and deliver a reader magnet?+
BookFunnel is the most popular choice among indie authors — it handles delivery, tracks downloads, and integrates with virtually every email service provider. It costs $20/year at the basic tier. StoryOrigin is a free alternative. Avoid sending files directly via email — delivery rates are lower and it creates unnecessary support overhead.
How do I convert reader magnet subscribers into Amazon reviewers?+
The conversion happens through your welcome sequence. In your first 2–3 emails, introduce yourself and your books, establish trust, and invite engaged subscribers to join your ARC team. Frame it as VIP early access. When you launch your next book, send ARCs 3–4 weeks in advance and make a single warm review request. Subscribers who downloaded your reader magnet and stayed on your list are already self-selected as interested readers — they convert to reviewers at a much higher rate than cold audiences.
Do reader magnets work for non-fiction authors?+
Yes — and they often convert better for non-fiction than for fiction, because non-fiction readers have a specific problem they want solved and are actively seeking tools. A practical checklist, cheat sheet, template, or condensed guide that delivers immediate value will outperform a generic chapter excerpt. The key for non-fiction: your reader magnet must solve a real, specific problem your ideal reader has right now.
