What is the best free newsletter tool?
beehiiv has the most generous free plan for newsletter writers: up to 2,500 subscribers with unlimited sends. Kit goes even higher for creators (free up to 10,000 subscribers), MailerLite is the friendliest for beginners, and Brevo wins if you have many contacts but mail rarely.
Which free plan is best depends on your situation. For a pure newsletter, beehiiv is hard to beat: 2,500 free subscribers, unlimited sends, plus a website and access to its recommendation network. It was built by the team behind a major newsletter operation, and you feel that in the growth features.
Kit is the outlier on raw numbers: free up to ten thousand subscribers, with paid newsletters supported from day one; automation is what sits behind the paid tier. MailerLite Free (500 subscribers, automation included) is the gentlest landing for someone who mostly wants a pleasant editor. And Brevo's unlimited contact storage with 300 sends a day suits anyone with a big existing customer base that gets occasional mail.
The free plan to skip nowadays is Mailchimp's: 250 contacts and 500 emails a month since the early-2026 cuts is simply too tight, and the paid tiers climb fast. All free plans show the tool's branding in your emails; that disappears with paid plans.
