What it is and why it matters

Marketing Skills, built by Corey Haynes, packages the practices he uses to grow a business into skills: SEO, ads, cold email, onboarding flows and social marketing. In the video it is presented as a way for a single person to do a decent job in areas they do not master, with little effort and almost no money. The approach aims to make marketing work more systematically.

Key points

Covers SEO, ads, cold email and onboarding flows
Includes social marketing: instead of posting more, it suggests which posts to comment on
Aimed at the solo founder without a marketing team

Where we saw it

The Next New Thing 2026-06-19 The hosts single this repo out as a hidden gem and say they tested it with its own author: the skills work simply and turn marketing into an almost engineering-like exercise. They cite the social skill, which instead of saying post more asks which ten posts you should comment on today, and mention asking it to build SEO sites or onboarding flows.
