About Substack

Substack is a publishing platform that allows writers, journalists, and content creators to publish newsletters and build subscription-based audiences. Founded in 2017, Substack has become a significant force in independent media, enabling creators to earn revenue directly from readers through paid subscriptions.

The platform handles payment processing, email delivery, subscriber management, and content hosting in a single integrated tool. Substack takes a percentage of subscription revenue as its business model, keeping the platform free to use at the basic level. Beyond newsletters, Substack has expanded to support podcasts, video content, and community features. Major journalists, authors, and niche experts have migrated to Substack, making it one of the most influential platforms in the creator economy.

Public Interest Registry does not guarantee its accuracy. Users accessing the Public Interest Registry RDAP service agree to use the data only for lawful purposes, and under no circumstances may this data be used to: a) allow, enable, or otherwise support the transmission by e-mail, telephone, or facsimile of mass unsolicited, commercial advertising or solicitations to entities other than the registrar's own existing customers and b) enable high volume, automated, electronic processes that send queries or data to the systems of Public Interest Registry or any ICANN-accredited registrar, except as reasonably necessary to register domain names or modify existing registrations. When using the Public Interest Registry RDAP service, please consider the following: the RDAP service is not a replacement for standard EPP commands to the SRS service. RDAP is not considered authoritative for registered domain objects. The RDAP service may be scheduled for downtime during production or OT&E maintenance periods. Queries to the RDAP services are throttled. If too many queries are received from a single IP address within a specified time, the service will begin to reject further queries for a period of time to prevent disruption of RDAP service access. Abuse of the RDAP system through data mining is mitigated by detecting and limiting bulk query access from single sources. Where applicable, the presence of a [Non-Public Data] tag indicates that such data is not made publicly available due to applicable data privacy laws or requirements. Should you wish to contact the registrant, please refer to the RDAP records available through the registrar URL listed above. Access to non-public data may be provided, upon request, where it can be reasonably confirmed that the requester holds a specific legitimate interest and a proper legal basis for accessing the withheld data.
