What brands should know before jumping into Substack

Brands like Rare Beauty and Saie are experimenting with Substack newsletters to increase community-building and engagement, but Allison Smith at ModernRetail warns that the platform doesn’t typically drive sales. Eriker Veurink, a Substack writer, advises brands, “You need someone in-house who can not only execute on writing but also think through your chat strategy, how you’re engaging with other Substack newsletters and what success looks like.” Marketing consultant Grace Clark says, “Clients are asking me, ‘How fun can we be?’ And that’s the right question to be asking.” {ModernRetail}
