Frequently Asked Questions
What is the email format of Substack?
Substack uses the first format, so Jane Smith would be jane@substackinc.com.
Who co-founded Substack and what roles do its co-founders hold today?
Substack was co-founded in 2017 by Chris Best, who serves as CEO, Hamish McKenzie, who holds the title of Chief Writing Officer, and Jairaj Sethi, who serves as CTO. All three remain active at the company today.
What is the Substack Defender program and who can use it?
The Substack Defender program, launched in 2020, provides independent journalists and creators with free legal support for cases involving defamation, copyright claims, and free speech challenges. It is available to publishers with at least 50 paying subscribers across 14 countries, including the US, UK, and Canada.
Does Substack support formats beyond written newsletters?
Yes, Substack supports written posts, podcasts, and video. In March 2026, Substack launched its built-in Recording Studio, which lets creators record solo videos or conversations with up to two guests and publish them directly on the platform without going live.
How can I find and verify the contact details of a Substack team member for outreach?
Substack follows a first-name-only email format at substackinc.com, so a direct email typically looks like firstname@substackinc.com. Tools like Clay can help you verify a specific team member's email address before reaching out.
