Substack released a new feature called “Reply Rules” on June 3, 2026, allowing creators to set custom guidelines for audience responses [1].
This update matters because it shifts the power dynamic between writers and their readers. By providing tools to shape interactions, the platform aims to reduce off-topic or unwanted replies that can often derail professional discourse.
The tool is currently available to all English-language publications worldwide [1, 2]. Creators can now establish specific rules for how users comment on posts, reply to Notes, or interact within the Chat function [1, 3]. These settings are designed to give writers greater control over the environment of their digital communities [1, 4].
Substack said the goal of the feature is to help creators shape interaction and minimize unwanted responses [1, 3]. This move reflects a broader trend in the creator economy where platforms are moving away from open-access forums toward more curated, moderated spaces.
Previously, creators had limited options for managing the flow of conversation. The new system allows for a more nuanced approach to community management, one that does not rely solely on deleting comments after they have been posted [1, 3].
By implementing these rules, writers can explicitly state the expectations for their community. This is intended to foster a more productive environment for both the author and the audience [1, 4].

The introduction of Reply Rules signals Substack's transition from a simple newsletter service to a comprehensive community management platform. By giving creators granular control over interaction, Substack is addressing the scalability problem of moderation, allowing writers to maintain a specific brand voice and community standard without requiring constant manual oversight.
