LetterBucket

LetterBucket is a newsletter platform built for creators, founders, operators, and media companies that want to own their audience. Its premise is that newsletters, websites, and subscribers should live in one system under your own domain and brand, instead of renting attention from a large platform. The editor is deliberately simple and focused on readability, so writing stays fast. After publishing, you send to subscribers and track results in real time. The site and blog functions publish articles automatically and support custom domains, while growth tools cover subscriber segmentation, welcome series, and recommendations.

- Create and send newsletters under your own brand

- Segment subscribers and run welcome series

- Track open and click performance

- Migrate content and lists from Substack, beehiiv, or ConvertKit

- Writers and creators who want audience ownership

- Founders using content as a real distribution channel

- Media companies that need to run publications efficiently

The free permanent plan is the headline, but free plan terms and limits can change, so do not assume they are permanent in practice and keep an export of your subscriber list current. Deliverability still depends on your sending behavior, since no platform can fix a neglected list or spammy content, and inbox placement is never guaranteed. As a smaller platform, the integration ecosystem is thinner than market leaders, so check that the tools you rely on connect. Paid use is described as a fixed infrastructure fee rather than revenue sharing, which is favorable, but confirm the current fee structure and limits before migrating a large list, since moving subscribers is disruptive if you later decide to switch again.
