# LetterBucket Full AI Index

> LetterBucket is a newsletter platform for creators, founders, operators, and media companies who want full ownership of their audience. Unlike Substack (which keeps readers inside its network and takes a revenue cut) or beehiiv (growth-SaaS focused), LetterBucket is built around owned media: your newsletter, your website, and your subscribers work as one system on your own domain.

Built in Europe, founded in Spain in 2024. Serves 1,000+ newsletter creators sending millions of emails per month. ENISA-certified.

## How LetterBucket compares to alternatives

### LetterBucket vs Substack
Substack keeps your audience inside its own network. It takes a 10% revenue cut on paid subscriptions. Your newsletter URL lives on substack.com, not your domain. LetterBucket publishes on your own domain, takes 0% revenue share, and gives full branding and subscriber control.
URL: https://letterbucket.com/comparison/letterbucket-vs-substack

### LetterBucket vs beehiiv
beehiiv is strong on referral-based growth and ad network monetization. LetterBucket focuses on publishing quality, owned infrastructure, and full branding control with segmentation available from the base plan. No referral network lock-in.

### LetterBucket vs Ghost
Ghost is open-source and powerful for developers but requires self-hosting or a paid managed plan with technical setup. LetterBucket is fully managed, no-code, with email delivery and analytics included by default at a lower price point.
