Every guide on building an author email list, including our own, tells you to add a link in your book’s front or back matter. Almost none of them quote Amazon’s actual policy on what that link is allowed to do. We went and read it. There’s one detail in it that changes how you should build your bonus page.

The Short Answer

Yes, reader magnets are allowed on Amazon KDP — but the link itself has a specific restriction that most reader-funnel advice skips over: a link that leads directly to a form asking for an email address, before the reader gets anything, is not a permitted external link under Amazon’s own Hyperlink Guidelines. The fix is straightforward once you know about it, and we cover it below.

What Amazon’s Hyperlink Guidelines Actually Say

Amazon publishes its rules for links inside Kindle books in its Hyperlink Guidelines. Two lines matter most for reader magnets:

External links should be present only if they directly enhance the reader experience and the content of the title.

And, more specifically:

Links to web forms that request customer information (e.g., email address, physical address, or similar) are prohibited.

Read literally, that second line is the one that catches most reader-magnet setups off guard. A link that takes a reader straight to a page whose first (and often only) element is an email opt-in form is, technically, a link to a web form requesting customer information — the exact thing the guideline names as prohibited.

Allowed vs. Prohibited, at a Glance

What’s Explicitly Allowed

The same guidelines list categories of links Amazon does permit, including:

• Links to previous or subsequent books in a series
• Links to multimedia content directly related to the book
• Links to “additional ancillary material” — Amazon’s own example wording includes checklists, assessment forms, craft patterns, and similar printable materials
• Links to relevant topical websites and author social media

Notice what these have in common: the reader gets something on arrival. None of them describe a page whose primary function is collecting an email address before delivering anything.

The Practical Fix: Value-First, Not Form-First

This doesn’t mean you can’t build a reader-magnet funnel. It means the order of operations on your bonus page matters:

• Not ideal: Reader clicks the link → lands on a page that immediately asks for an email address → gets the bonus only after submitting.
• Better aligned with the guidelines: Reader clicks the link → lands on a page that gives immediate, direct access to the bonus (a download link, an embedded reader, a “click here to get it” button) → is invited, separately and optionally, to join your email list for more.

The second structure treats the email signup as a bonus-on-top rather than a toll-gate, which is a meaningfully different page from a compliance standpoint — and, as a side benefit, tends to convert better anyway, since gating content behind a form is exactly the kind of friction that makes readers bounce.

Does This Mean Every Reader-Magnet Guide (Including Ours) Is Wrong?

Not wrong, but incomplete. Most guides, including ours until now, describe the mechanics of the funnel — pick a bonus, build a page, place a link — without walking through this specific structural detail. It’s an easy thing to miss, because a simple “name and email” opt-in page is the default template in most landing-page tools and most page-building tools, including general-purpose ones and author-specific ones alike. Whether you’re building a page by hand or using a tool like AI Reader Rocket, the responsibility for how the page is structured — form-first versus value-first — sits with you as the page’s actual configuration, not with any single tool’s default template. Check the page you end up with, not just the tool you used to build it.

How Enforcement Actually Works

Amazon’s own guidelines don’t spell out an enforcement process in detail, and we can’t verify from official sources exactly how consistently this specific rule is checked in practice. What independent author-community writeups on this topic consistently describe is a range of outcomes from no action at all up to a book being quietly delisted until the link is fixed, with repeated or more serious violations carrying account-level risk. Treat that as a reasonable risk range to plan around, not a guaranteed outcome either way — and treat this whole article as a starting point for understanding the policy, not a legal or compliance guarantee. Read the official guidelines yourself before publishing, since Amazon updates its policies periodically.

A Compliant Bonus-Page Structure, Step by Step

1. Lead with the thing you promised. A visible download link, an embedded file, or a “read online” button — accessible without submitting anything.
2. Add the email signup below or beside it, framed as optional. “Want more like this? Join the list” reads very differently from a form blocking the download.
3. Keep the page otherwise simple. One clear action to get the bonus, one clear (separate) action to subscribe.
4. Test it as a reader would. Load the page fresh, without cookies or a prior visit, and confirm you can get the bonus without typing an email address anywhere.

This is the same underlying structure whether you build the page by hand or generate it with a tool — see our complete guide to building an email list from your KDP books for the full funnel, and our reader magnet idea list if you haven’t picked a bonus yet.

What About the Link Placement Itself?

The structural rule above is about the destination page. Where you place the link inside your manuscript is a separate question with its own best practices — front matter versus back matter, how to word the call-to-action, and formatting for print versus ebook editions. We cover that in full in our KDP back matter link strategy guide.

Does This Apply to QR Codes and Print Editions Too?

The guidelines are about the destination, not the format of the link itself, so yes — a QR code in a paperback that leads to a form-first opt-in page carries the same consideration as a clickable link in an ebook. If you sell in both formats, it’s worth checking the landing page once, since the same URL (or QR code pointing to it) typically serves both. For the mechanics of setting up a short, print-friendly link in the first place, see the link-formatting section of our back matter link strategy guide.

Frequently Asked Questions

Does this apply to both fiction and nonfiction books? Yes. The Hyperlink Guidelines apply to external links generally and aren’t genre-specific.

Can I still ask for an email address on the bonus page at all? Yes — the guideline is about sequencing, not about whether an email field can exist on the page at all. Deliver the bonus first, then offer the signup.

What if my existing bonus page already gates the download behind a signup form? Consider restructuring it so the reward is accessible first. It’s a relatively small change to an existing page and removes a compliance question you don’t need to be carrying.

Is this guideline new? We can’t confirm a specific date it was introduced from the public guidelines page alone; treat the current wording as what’s in effect now, and re-check the official page periodically since platform policies change.

Where can I read the actual policy myself? Directly on Amazon’s site: KDP Hyperlink Guidelines.

Bottom Line

Reader magnets are allowed, and building an email list from your KDP readers is still one of the highest-leverage things an author can do. The one adjustment worth making, based on Amazon’s own published guidelines, is structural: give readers the thing you promised before you ask them for anything, not after. It’s a small change to a bonus page and it takes the compliance question off the table.
