Starting a newsletter without a monthly bill is realistic in 2026. Several platforms offer a real free-forever tier. The catch is that "free" means different caps: subscribers, monthly sends, automations, and monetization. This guide compares the main free options so you can pick by list size and what you need to do on day one.

1. Kit Free: best for the largest free list

Kit's Free plan help page says the Free plan costs $0 per month for as long as you stay under 10,000 email subscribers. It includes unlimited forms and landing pages, unlimited email broadcasts, tagging and segmentation, digital products and subscriptions, A/B testing on broadcasts, Creator Network recommendations, and API access.

What needs a paid plan, per the same page: visual automations and the automation template library, email sequences, rules and RSS campaigns, and earning from Paid Recommendations.

Choose Kit Free if you care most about list size and sending broadcasts without a monthly fee.
Watch out: serious welcome sequences and automation funnels need Creator or higher.

2. beehiiv Free: best free media-style stack

beehiiv's pricing page lists Free at $0 with up to 2,500 subscribers, unlimited email sends, and no credit card. Free includes newsletters, website, podcast, campaign analytics, the recommendation network, templates, and API access (read). Paid subscriptions with a 0% take rate, the ad network, and email automations start on Lite.

Choose beehiiv Free if you want a publication with a site and podcast in one free account.
Watch out: the 2,500-subscriber cap is lower than Kit's; monetization features that need Lite will push you to pay earlier if you charge readers.

3. systeme.io Free: best free plan if you also sell

systeme.io's pricing page says the free plan never expires and needs no credit card. It includes 2,000 contacts, unlimited email sends, 3 sales funnels, 1 blog, 1 course, 1 affiliate program and 1 custom domain. Limits are tighter on automation (1 rule) and email campaigns/sequences (1).

Choose systeme.io Free if email is part of selling courses, coaching or digital products.
Watch out: it is built around funnels and selling, not a media-style ad network or recommendation graph.

4. MailerLite Free: best small-list free automations

MailerLite's free plan page lists up to 250 subscribers, 2,500 monthly emails, 2 user seats, 3 visual automations, 1 website and 1 landing page, 1 digital product or booking, and 3 sign-up forms, with no credit card required. A June 2026 free-plan update reduced the old 500-subscriber / 12,000-email caps to these figures (MailerLite free plan FAQ).

Choose MailerLite Free if your list is tiny and you want free automations immediately.
Watch out: 250 subscribers is a hard ceiling for growing newsletters; Kit or beehiiv free plans go much further on list size.
Our MailerLite affiliate application is still pending, so there is no affiliate link here yet.

5. Substack: free publishing at any size

Substack says publishing is free no matter how many subscribers you have. If you turn on paid subscriptions, Substack keeps 10% of subscription revenue, and Stripe charges its own fees (Substack Help). A custom domain is an optional one-time $50.

Choose Substack if you want $0 fixed cost and will only pay when paid subscriptions earn money.
Watch out: the 10% cut grows with revenue; alternatives with a 0% platform cut are covered in our Substack alternatives guide.
We don't currently have an affiliate relationship with Substack.
