Mastodon Adds Newsletters to Boost Open Social Web
Mastodon has added email newsletter functionality in its Mastodon 4.6 release, enabling writers to send posts directly to subscribers’ inboxes even when recipients do not have Mastodon accounts. The feature is intended to help creators and institutions grow portable audiences on the decentralized fediverse, and is positioned toward organizational users alongside Mastodon’s hosting and moderation services. Mastodon 4.6 also includes refreshed user profiles and a "Collections" feature. The company noted email sending can materially increase server operating costs, so newsletters are not a default capability and require appropriate server permissions or hosted options. Mastodon hopes the email integration will attract publishers, independent journalists and anonymous subscribers and expand reach beyond its reported ~735,000 monthly active users.
Adds a new direct-to-inbox distribution channel on a decentralized social platform, which could help creators build portable audiences and reduce reliance on major walled gardens—relevant to publishers and MarTech but not industry-shifting.

Mastodon Revamps for Creators with Exciting New Features
Mastodon announced product updates aimed at making the decentralized, open-source social platform more approachable for newcomers and more attractive to creators. The organization — part of the fediverse using the ActivityPub protocol — said its expanded development team and a newly hired designer have driven a roadmap that includes improved onboarding, promotion of smaller servers, new admin tools (external blocklists, content scanning, remote media serving), and creator-facing features such as a redesigned profile, enhanced compose experience, email notifications for followers without accounts, Quote Posts and a Collections recommendation feature. The update follows leadership changes: founder Eugen Rochko stepped down as CEO and Felix Hlatky became executive director, with Dr. Marius Rothermund providing legal expertise during a nonprofit restructuring covering the U.S., Germany and Belgium.
Mastodon Revamps Profiles to Improve Usability
Mastodon is rolling out a redesign of user profiles to make its decentralized social network easier to use for mainstream audiences and organizations. The changes replace dual post views with a single “Activity” tab and a dropdown to toggle replies and boosts, surface hashtags at the top of profiles, simplify pinned-posts behavior, and add explanatory UI for dual @handles. Profiles gain more customizable visibility (hide Media/Featured tabs), side-by-side custom fields editable on iOS and Android, and easier access to link verification and image cropping/alt text. The update is available initially on mastodon.social and nightly builds, with a wider release planned in the Mastodon 4.6 software update in the coming weeks. Mastodon’s monthly active users are about 800,000, down from roughly 1 million at peak.
SPUR launches AI content tracking standard, invites OpenAI, Google to board
A coalition of media organizations including the Guardian, Financial Times, BBC, Sky, and the AP has released a new standard for tracking how AI tools use publishers' content. The Standards for Publisher Usage Rights (SPUR) initiative published its content telemetry standard on October 2, 2026. The standard creates a process to track and report when content is retrieved, grounded, cited, presented, and engaged with by AI tools, and report usage back to publishers. SPUR has invited OpenAI, Anthropic, Google, Meta, and Microsoft to join its new AI Licensing Advisory Board to help shape implementation. The board aims to ensure tracking rules work for both publishers and AI companies. SPUR is also developing agent tooling for AI companies to adopt the standard, supporting transparent reporting and licensing. Pilot programs with tech and AI companies are planned.
