Description
LetterBucket is a newsletter platform designed for creators, founders, and operators who want to own their audience. It lets you create and send a newsletter, publish a website and blog, and grow your audience from one workspace on your own domain, so your newsletter and website work as a single owned system rather than being split across tools.
You keep full ownership of your subscriber list on every plan, can export it at any time as a CSV, and retain ownership even if you cancel. Unlike networks such as Substack or Beehiiv, LetterBucket publishes everything on your domain and takes zero revenue share on paid newsletters, sponsorships, or any monetization.
The platform includes an email editor, custom domains, automations and welcome series, analytics, segments, a template library, polls, subscriber management, and an AI writing assistant. You can import an existing list via CSV or a one-click migration tool from Substack, Beehiiv, Mailchimp, Ghost, and others, and a free plan supports up to 1,000 subscribers with paid tiers adding more features.
