An author email platform has to do three jobs well: collect readers, deliver dependable launch emails, and stay affordable while the list grows. MailerLite and Kit both cover those basics, but their free plans make very different tradeoffs.
The short answer
Choose MailerLite if you have a small list and want simple automations, more visual design options, and a lower-priced path to paid features. Choose Kit if you want room to grow a large free list, prefer a creator-focused tagging model, and can live without automated email sequences until you upgrade.
For many new authors, MailerLite is the more practical launch system because its free plan includes three automations. Kit’s free plan is unusually generous on subscriber capacity and broadcasts, but its most useful nurture tools—visual automations and email sequences—sit on the Creator plan.

The biggest difference: free capacity versus free automation
Kit lets a new creator keep up to 10,000 subscribers on its free plan and send unlimited broadcasts. That is an enormous runway if your strategy is a straightforward newsletter: collect readers, tag them, and send regular updates or launch announcements.
The catch matters for authors. A reader magnet normally works best with an automated welcome sequence: deliver the bonus, introduce your books, set expectations, and invite the reader to take one next step. Kit reserves unlimited email sequences and visual automations for its paid Creator plan.
MailerLite caps the free list at 250 subscribers and monthly sending at 2,500 emails, but includes three automations. That smaller allowance can still support a polished welcome funnel while an author proves that the lead magnet and emails work. When the list passes 250 active subscribers, sending is locked until the author upgrades or reduces the active count.
Pricing for a growing author list
MailerLite
- Free: up to 250 subscribers and 2,500 monthly emails.
- Comfort: starts at $12 per month and includes more templates, up to 50 automations, 10 websites or landing pages, and removal of MailerLite branding.
- Power: starts at $25 per month and adds unlimited monthly emails, automations, forms, landing pages, and user seats, subject to fair-use terms.
MailerLite says paid pricing is based on subscriber count and sending volume. That makes it important to compare the exact tier for your real list—not only the attractive starting price.
Kit
- Free: up to 10,000 subscribers, unlimited broadcasts, unlimited landing pages and forms, tagging, segmentation, and selling tools.
- Creator: $39 per month for up to 1,000 subscribers, or $390 billed annually. It adds unlimited visual automations and sequences, integrations, A/B subject testing, removal of Kit branding, RSS campaigns, and support.
- Pro: $79 per month for up to 1,000 subscribers, or $790 billed annually. It adds deeper analytics, engagement scoring, collaborative editing, more testing, and a referral system.
Kit becomes much more expensive when an author needs automated sequences, but the free plan delays the subscriber-count upgrade far longer. The best economic choice depends on whether list size or automation is your first constraint.
Which editor is better for author newsletters?
MailerLite offers drag-and-drop, rich text, and custom HTML approaches, plus templates and a stock image library. It is a better match for authors who want visually designed newsletters with book covers, event panels, boxed calls to action, and storefront-style sections.
Kit is oriented toward creator emails that feel direct and personal. It still supports custom templates on paid plans, but its strongest appeal is not decorative design. It is the creator workflow around forms, tags, broadcasts, recommendations, digital products, and automated sequences.
Neither visual style is universally better. A simple letter from the author can outperform a heavily designed email when the voice and offer are strong. Choose the editor you will actually use every month.
Automation: the author use cases that matter
- Reader-magnet delivery: send the promised story, checklist, or bonus chapter immediately.
- Welcome sequence: introduce the author, books, genre promise, and reading order over several days.
- Launch sequence: segment advance readers, buyers, and general subscribers so each group gets relevant messages.
- Backlist nurture: guide a reader from one book or series to the next.
- Re-engagement: identify readers who no longer open or click before paying to retain them.
MailerLite gives a beginner enough free automation to build the first two workflows. Kit’s free plan can deliver broadcasts and collect subscribers, but an author who wants a multi-email welcome path should budget for Creator or use a temporary manual process.
Choose MailerLite if…
- You have fewer than 250 subscribers and want an automated reader-magnet sequence now.
- You prefer a visual newsletter builder and more designed layouts.
- Your budget makes Kit’s paid entry price uncomfortable.
- You want websites, landing pages, forms, and a small digital product in one inexpensive starter account.
- You send often enough to value Power’s unlimited sending later.
Choose Kit if…
- You expect the list to grow beyond 250 quickly but only need broadcasts at first.
- You organize readers with tags and segments across genres, series, or products.
- You plan to sell digital products, paid newsletters, or subscriptions from the same platform.
- You want creator-network recommendations and a creator-centered ecosystem.
- You are ready to pay for robust visual automations and sequences.
A simple decision for most authors
Starting from zero with a reader magnet? MailerLite is the better first test. Build one landing page, one form, and a short welcome automation. The 250-subscriber cap is enough to learn whether readers want the offer before taking on a paid bill.
Already bringing in hundreds of subscribers from a launch, podcast, or social audience? Kit’s 10,000-subscriber free allowance can prevent an immediate upgrade. Just decide whether broadcast-only email is acceptable or whether the Creator plan belongs in the budget from day one.
Running a mature author business with several series and products? Compare the paid automation builders, reporting, integration list, and support using your actual workflow. At that stage, migration time and missing integrations can cost more than the monthly price difference.
Before you move your list
- Remove bounced and chronically inactive addresses.
- Export subscribers, tags, segments, forms, and automation logic from the old platform.
- Authenticate your sending domain before a launch week.
- Rebuild one welcome path and test every link on desktop and mobile.
- Send to the most engaged segment first, then watch bounces and complaints.
Final verdict
MailerLite wins for a small, budget-conscious author list that needs automation and flexible design immediately. Its free ceiling is low, but the included starter automations solve a real author problem.
Kit wins for free list capacity and a long-term creator business. Its free plan is excellent for forms and broadcasts, while the paid Creator tier becomes compelling when tagging, sequences, integrations, and product sales all support the same audience.
Do not choose based on the subscriber limit alone. Write down the first automation you need, the list size you expect in twelve months, and the monthly revenue or book sales email must support. The right platform is the least expensive one that removes your actual bottleneck.
If you would rather combine an author website, mailing-list tools, blog, events, and optional direct book sales in one hosted system, read our Tertulia for Authors review. Its Basic plan collects subscribers; full email campaigns are part of Pro.
