Let Creators Choose Their Format
- Let writers choose the format that fits them: longform, podcast, video, or none of the above.
- Do not force creators into social features; Substack provides optional tools like the feed and chat.
RealReal's 'Real Girl' Fashion Column
- The RealReal launched a Substack with an anonymous fashion writer called The Real Girl to cover shows and brand usage.
- Christina Loff describes it as a gossip-girl style approach that connected readers to the brand voice.
Make Brand Substacks Editorial-Led
- Brands should be founder-led or hire trained writers to run their Substack for authentic storytelling.
- Avoid launching a Substack with only promotional product posts; have a clear editorial reason to be there.
