# r/Substack self-promotion norms and what members ask r/Substack is a forum about the platform itself: how to start a publication, why growth has stalled, what to do about a support problem, and whether another service would suit better. The description reproduced by two directories carries a short rule, no self-promotion, so posts that share a writer's own publication or a vendor's product cut against the stated purpose. For a brand with a newsletter tool or service, the opening is narrow. Answer platform and growth questions on their merits, give a fair comparison when someone asks about switching, and disclose any tie in the same reply. Many threads are frustration about slow growth or platform changes; a rival's pitch there tends to read as opportunism, so stay out of those. Community rules change. Read the sidebar and the pinned rules in r/Substack before you post.
