1. ConvertKit (Kit) — Best Overall for Authors
Our Pick — Best for Professional Authors
ConvertKit (recently rebranded to Kit) is the platform most professional authors use, and for good reason. It’s built for creators, not corporations.
Free tier: Up to 10,000 subscribers (limited features) Paid plans: From $29/month for full features
ConvertKit dominates the author space because it prioritizes what writers need: clean text emails that land in inboxes, powerful automation for launch sequences and reader magnets, and tagging systems that let you segment your audience by genre, book interest, or engagement level.
What authors love:
- Visual automation builder for welcome sequences and launch funnels
- Tagging and segmentation that lets you send different content to fiction vs. nonfiction readers
- Landing page builder for reader magnets (no website needed)
- High deliverability rates — your emails actually reach inboxes
- Creator-focused community and support
What could be better:
- Email template design is intentionally simple (text-focused)
- The free tier limits automation features
- Gets expensive above 10,000 subscribers
Best for: Authors who want professional email marketing with automation, segmentation, and reliable deliverability. Ideal if you’re running book launches, have multiple series, or sell directly to readers.
2. MailerLite — Best Value for Money
Free tier: Up to 1,000 subscribers Paid plans: From $10/month
MailerLite offers the best feature-to-price ratio for authors on a budget. The paid plan includes automation, landing pages, a website builder, and even a simple digital product selling feature — all for roughly a third of ConvertKit’s price.
What authors love:
- Drag-and-drop email editor with attractive templates
- Automation workflows that rival more expensive platforms
- Built-in pop-up forms and landing pages
- Excellent deliverability at a fraction of the cost
- Survey and quiz features for audience engagement
What could be better:
- Free tier is limited to 1,000 subscribers (ConvertKit offers 10,000)
- Fewer third-party integrations than ConvertKit or Mailchimp
- Less robust tagging than ConvertKit
Best for: Authors who want professional email marketing without spending $30+/month. Perfect for authors building their first list or those who don’t need advanced automation.
3. Substack — Best for Writer-Publishers
Free tier: Unlimited free subscribers Paid plans: 10% of paid subscription revenue (no monthly fee)
Substack blurs the line between newsletter and publishing platform. You write, readers subscribe, and Substack handles delivery. It’s the simplest option — no templates to design, no automation to set up, just writing.
What authors love:
- Zero upfront cost — you only pay when readers pay you
- Built-in discovery (Substack’s network helps readers find you)
- Clean reading experience that feels like a blog/magazine
- Paid subscription option lets you monetize directly
- Community features (comments, discussions, Notes)
What could be better:
- Very limited automation (no welcome sequences, no drip campaigns)
- You can’t segment subscribers effectively
- Substack owns the reader relationship (not ideal for launch marketing)
- 10% revenue cut on paid subscriptions is significant at scale
- Limited integration with other tools
Best for: Authors who want to write a newsletter as content (like a column or serialized fiction) rather than using email as a marketing tool. Great for building a public writing practice. Not ideal for book launch marketing.
4. Mailchimp — Best for Template Design
Free tier: Up to 500 contacts (limited) Paid plans: From $13/month
Mailchimp is the biggest name in email marketing and offers the most polished visual email builder. If you want your newsletters to look like magazine layouts with images, columns, and designed headers, Mailchimp’s editor is the best.
What authors love:
- The most sophisticated drag-and-drop email builder
- Extensive template library
- Advanced analytics and reporting
- Massive integration ecosystem (connects to everything)
- Brand familiarity — readers trust Mailchimp-powered emails
What could be better:
- Pricing has increased significantly — expensive above 1,000 contacts
- The free tier is severely limited (500 contacts, limited features)
- Not built for creators/authors (business-focused interface)
- Over-designed emails often perform worse than simple text (lower deliverability)
Best for: Authors who prioritize visual email design and need extensive integrations. Better for nonfiction authors with brand-heavy content than fiction authors who just need to connect with readers.
5. Buttondown — Best for Minimalists
Free tier: Up to 100 subscribers Paid plans: From $9/month
Buttondown is a stripped-down newsletter tool for writers who just want to write and send. No bloated features, no complex interface — just a Markdown editor, a subscriber list, and a send button.
What authors love:
- Beautifully simple interface — no learning curve
- Markdown support for writers who prefer plain text
- RSS-to-email for automatic blog-to-newsletter posting
- Ethical company with transparent pricing
- Great for developers and tech-savvy writers
What could be better:
- Very small free tier (100 subscribers)
- Minimal automation capabilities
- No visual email builder — text-only or Markdown
- Small community compared to major platforms
Best for: Writers who value simplicity over features and prefer a clean, no-distraction email tool. Ideal for personal newsletters with a small, engaged audience.
6. Beehiiv — Best for Newsletter-First Authors
Free tier: Up to 2,500 subscribers Paid plans: From $39/month
Beehiiv is the newest major player, built specifically for newsletter creators who see the newsletter itself as the product (not just a marketing channel for books).
What authors love:
- Built-in recommendation network for subscriber growth
- Monetization tools (ads, paid subscriptions, boosts)
- Clean, modern reading experience
- Analytics focused on growth and engagement
- Web-accessible archives that function as a blog
What could be better:
- Paid plans are expensive ($39/month to start)
- Fewer automation features than ConvertKit
- Relatively new — less established track record
- Overkill if you just need basic email marketing
Best for: Authors building a newsletter as a primary content product — think literary criticism, industry analysis, or serialized fiction with a paid tier.
What Features Matter Most for Authors?
Deliverability (Non-Negotiable)
If your emails don’t reach inboxes, nothing else matters. ConvertKit, MailerLite, and Buttondown consistently rank highest for deliverability. Mailchimp and Substack are good. Test with your own list — deliverability varies by audience.
Automation
For book launches, you need:
- Welcome sequences for new subscribers
- Launch email sequences (pre-order → launch day → follow-up)
- Tagging based on subscriber interests
- Reader magnet delivery automation
Best automation: ConvertKit > Mailchimp > MailerLite > Beehiiv > Substack/Buttondown
Subscriber Ownership
You should always be able to export your full subscriber list (emails, names, tags). This is critical — if a platform shuts down or you want to switch, your list is your most valuable asset.
All platforms listed here allow CSV export. But Substack makes switching harder because your content and audience are more tightly integrated into their platform.
Landing Pages and Forms
Authors need signup forms and landing pages for reader magnets. ConvertKit, MailerLite, and Beehiiv offer the best built-in options. Mailchimp’s are functional but business-focused.

FAQ
What is the best newsletter platform for authors?
The best newsletter platform for most authors is ConvertKit (Kit) because it offers powerful automation, excellent deliverability, creator-focused features, and a generous free tier of 10,000 subscribers. MailerLite is the best budget alternative at $10/month. Substack is best for writers who want to publish a newsletter as content rather than use email for marketing.
Is Substack good for authors?
Substack is good for authors who want to publish a newsletter as a content product — serialized fiction, literary criticism, or regular essays. It’s less ideal for book launch marketing because it lacks automation, segmentation, and advanced email features. If your primary goal is selling books, ConvertKit or MailerLite are better choices.
How much does an author newsletter cost?
An author newsletter costs $0-$39/month depending on the platform and subscriber count. ConvertKit is free up to 10,000 subscribers, MailerLite free up to 1,000, and Substack is free for sending (10% cut on paid subscriptions only). Most authors pay $10-$30/month once they have a few thousand subscribers and need full features.
Can you switch newsletter platforms without losing subscribers?
Yes, you can switch platforms by exporting your subscriber list as a CSV file and importing it into the new platform. All major platforms support this. However, you’ll need to re-verify subscribers in some cases, and you’ll lose platform-specific data (open history, automation sequences). Plan the switch during a low-activity period, not during a book launch.
How many subscribers does an author need to sell books?
There’s no magic number, but most successful book launches happen with at least 500-1,000 engaged subscribers. A smaller, engaged list outperforms a larger passive one. Focus on open rates above 30% and click rates above 3% rather than raw subscriber count. Even 200 highly engaged readers can drive a meaningful launch.
