Common questions
See all questions on the FAQ page- Do authors need an email newsletter?
- Most authors benefit from one. In a mid-2026 Written Word Media survey of 582 self-selected authors, cited by The WriteLight Group, newsletter use rose from 39% among authors earning up to $500 per month to 73% among those earning $2,500 to $10,000. A newsletter is an audience you control.
- When should I start marketing my book?
- Start marketing at least 10 to 12 weeks before your book is published, according to Reedsy. That window gives you time to build an email list, line up reviewers, and plan launch content. If you are past that point, start now: the same steps still work, they just take longer to build momentum.
- When should I contact book reviewers?
- Begin researching reviewers 3 to 4 months before publication, according to ManuscriptReport. Reviewers often schedule ahead, so an early list improves your chances of reviews landing near launch. Track each contact in a simple spreadsheet with their name, focus, request date, and response, then follow up politely once.
- Where can I promote my new book?
- Promote your new book where your readers already spend time: your email list, the social platform your audience uses most, podcasts and media in your topic, local bookstores and libraries, and author communities. Since 80% of ebook sales run through Amazon according to Ulatus, make sure your book page there is complete.
- What makes a good lead magnet for authors?
- A good lead magnet solves one specific problem fast. Authors Unite lists formats such as a checklist or template that solves a specific problem in 15 minutes, or a free mini-course delivered over 5 to 7 days. Build it from a chapter of your book so it naturally leads readers back to your work.
