Once an author has a working sign-up route and a handful of subscribers, the next hesitation is usually about content: what is actually worth sending? A common, understandable fear is that the only alternative to silence is a repeated pitch to buy the book, which quickly feels awkward to write and unwelcome to receive. That is not the only option, and it is rarely the effective one.
This guide sets out a working range of content options across fiction, memoir, non-fiction and business writing, and makes the case for variety over repetition. It builds on [how do I turn book readers into email subscribers](/resources/book-sales-growth/how-do-i-turn-book-readers-into-email-subscribers), which covers how readers reach the list in the first place.
What a newsletter does not need to be
A subscriber who signed up because they enjoyed a book is not signing up to be sold to repeatedly. An email list that only ever says "buy my book" quickly earns unsubscribes, because it gives readers no reason to keep opening it. The purpose of most newsletter content is to maintain a relationship between books, not to close a sale every time.
What can go in a newsletter
- Progress on a work in progress, written honestly rather than as a countdown to a purchase
- Behind-the-scenes detail about how the published book was written or researched
- Recommendations of other books or work the author genuinely admires
- Character or world notes, for fiction with a following invested in its detail
- Short essays or reflections connected to the book’s themes
- Genuine personal insight, shared at the author’s own comfort level
- Notice of events, appearances or launches
- Bonus material created specifically for subscribers
- Useful, practical guidance connected to the book’s subject, for non-fiction
- Clear announcements, when there is genuinely something to announce
A content matrix by type
| Content type | Why a reader may care | Frequency idea | Suits |
|---|---|---|---|
| Writing progress | Feels like an insider look at the next book | Occasional, when there is real news | Fiction, memoir |
| Behind-the-scenes / research | Adds depth to a book already enjoyed | Every few emails | All types |
| Recommendations | Useful even between the author’s own books | Occasional | Fiction, non-fiction |
| Character/world notes | Rewards invested series readers | For series with a following | Fiction |
| Essays/reflections | Builds voice and connection over time | Monthly or less often | Memoir, non-fiction |
| Useful topic guidance | Delivers standalone value regardless of book sales | Regular, if sustainable | Non-fiction, business |
| Event or launch news | Genuinely time-sensitive and relevant | As it happens | All types |
| Direct announcement | Clear, honest, occasional news readers actually want | Rare, and clearly flagged | All types |
For fiction
Fiction readers on a mailing list are often there because they liked the voice or the world of the book, so content that extends that experience tends to land well: writing updates, cover reveals, research snippets that informed the plot, occasional deleted scenes where appropriate, world notes for series readers, and recommendations of comparable books.
For memoir
Memoir readers should never be given the impression that a newsletter obliges the author to keep disclosing private or difficult material. Reasonable content includes reflections on writing and publishing the book, the themes it explores, event updates, related reading, and carefully chosen personal commentary, shared entirely at the author’s discretion.
For non-fiction
Non-fiction newsletters can lean into ongoing value: useful ideas connected to the book’s subject, frameworks the author uses, case examples where the author has permission to share them, answers to reader questions, and relevant new developments in the field. This kind of content can be useful even to a reader who has not yet bought the book.
For business authors
Business authors can connect a newsletter to book themes, professional expertise, speaking opportunities, articles, and future work, since readers of a business book are often interested in the author’s wider professional world. This should stay a genuine newsletter rather than becoming a stream of sales-prospecting messages disguised as reader content.
On frequency
Planning a few emails ahead
Rather than deciding content issue by issue under pressure, it can help to sketch a short list of realistic ideas in advance.

Common mistakes
- Treating every email as a sales opportunity. This trains subscribers to expect a pitch and tune out, or unsubscribe, quickly.
- Committing to a frequency that cannot be sustained. A weekly promise abandoned after a month damages trust more than an honest occasional schedule.
- Assuming memoir subscribers want ongoing personal disclosure. A memoirist can share as much or as little as they choose beyond the book itself.
- Sending nothing between launches. Long silences make readers forget why they subscribed in the first place.
- Turning a business newsletter into cold outreach. This confuses a reader relationship with a sales funnel and tends to backfire.
Frequently asked questions
How often should I email my list?
Whatever is sustainable and consistent for the individual author. A realistic quarterly schedule kept up for years is more useful than an ambitious weekly one abandoned after a month.
Is it ever okay to just announce a new book?
Yes. A clear, honest announcement is a legitimate and expected use of an author newsletter; the issue is making every email an announcement rather than an occasional one.
What if I do not have much to say between books?
Behind-the-scenes detail, recommendations, and reflections connected to existing work can fill genuine gaps without inventing artificial news.
Should memoir authors keep sharing personal stories after the book is out?
Only as much as they are comfortable with. There is no expectation of continued disclosure, and reflections on themes or writing can substitute for further personal revelation.
