Our verdict on Letterbase

Letterbase brings newsletter creation, email delivery, and a public issue archive together for independent writers and publishers. Its block editor supports headings, images, quotes, buttons, and embeds; AI draft generation uses Claude. Readers can access free issues on the web, while paid issues can be placed behind a paywall. Subscriber tools include tags, segments, tiers, CSV import and export, and bulk actions, making the product relevant to creators who want publishing and audience management in one service.

Audience growth is a notable part of the product rather than an add-on limited to email delivery. Letterbase offers referral links, rewards, a leaderboard, an email widget, and a newsletter cross-promotion network. That combination may suit publishers who want readers to help drive discovery. Paid subscriptions are processed through Stripe, and the vendor says it charges no platform fee on those subscriptions; payment processing fees apply. The listed Creator plan includes unlimited issues and archives, an AI draft assistant, paid subscriptions, and custom sender details. Publisher adds referrals, Boost network access, CSV import and segment tags, and open-rate and click analytics. Pro adds multiple publications, team seats, priority deliverability review, and dedicated Slack support.

The plans are flat monthly subscriptions, with subscriber limits varying by tier. A starting price of 29 is listed, but the amounts for individual plans are not specified here, so buyers should compare current plan pricing before choosing a tier. Letterbase is cloud-based and available on the web, with email delivery through Resend and support via email. Its focus on email and web publishing, paid archives, and referrals is a fit for creators building paid issues and subscriber growth loops. Publishers who need analytics on the Creator tier, or whose workflow depends on channels beyond web and email, may prefer another platform.
