Mastodon adds email newsletters to boost creator reach

Mastodon, the decentralized social networking platform, is launching email newsletters to help creators build audiences outside of Big Tech ecosystems. The feature is designed to address the open social web’s growth challenges by allowing writers to send their posts directly to subscribers’ inboxes. By leveraging email, Mastodon may appeal to those who want to support creators outside of Big Tech platforms like X and Threads, without requiring subscribers to sign up for a new social network account.

Arriving as part of the Mastodon 4.6 software update—which also introduces refreshed user profiles and support for “Collections,” the platform’s version of suggested follow lists known elsewhere as “Starter Packs”—the newsletter feature is not enabled by default. The company explained that it chose not to make newsletters a default feature because sending emails can “significantly rack up the costs of operating a Mastodon server.” Consequently, creators who want to use the feature must have an assigned role with the correct permissions on their server, which requires setting up their own server, using one hosted by Mastodon, or coordinating with an existing server operator. For now, the company notes that the feature is intended more for its institutional users, aligning with its recent efforts to offer hosting and moderation services to organizations running their own servers.

The integration of email could allow Mastodon to evolve beyond being just another alternative to X. Currently, Mastodon has 735,000 monthly active users, which is down from a peak of over 2 million. Meanwhile, the fediverse—the wider open social web—has over a million active accounts. By allowing users to subscribe using only an email address, Mastodon hopes to expand its footprint. The platform’s default post character limit is 500 characters, though individual server administrators can modify this limit, which means some servers could be set up specifically for the distribution of longer posts. This setup could appeal to independent journalists, bloggers, and media organizations looking to reach audiences without tracking them for privacy reasons, while allowing creators to maintain portable audiences that they can migrate to other servers.

Why it matters

This move represents a strategic shift for Mastodon to reduce creator reliance on Big Tech ecosystems by leveraging email, a universal communication tool, to drive audience growth.
