Meet The Founder: Gavin Hewitson from In-Box

I sat down with Gavin Hewitson, founder of 7 Figure Agency In-Box, an email and SMS marketing agency for ecommerce brands, run from Mexico City. Gavin went from touring as a stand-up comedian (and not making any money) to freelancing at an email agency by day, to building his own: 15 full-time staff, 23 with part-timers, and over 700 videos on YouTube. What we cover: Turning every YouTube video into blog articles: about five a day, linking back and forth for SEO One month of output: 20 YouTube videos, 10 newsletters, #4 in the world for Klaviyo email marketing on Upwork Directing traffic instead of doing the work, and the 8-12 / 12-4 / 5-8 day DIY vs hiring an agency: the opportunity cost founders don't measure Why the burden of proof is on the agency, and agreeing on a number before you hire YouTube as the biggest form of social proof for an agency Where AI helps, where it doesn't, and why open rates and click rates don't actually matter Training Claude on every video transcript to build an internal strategist and run account audits against your own SOPs Chapters 0:00 Intro 0:23 Turning YouTube videos into 5 blog posts a day 2:18 Gavin Hewitson, In-Box: email + SMS from Mexico City 3:35 From stand-up comedy to email marketing 5:38 What drives him now (and the dating scene) 7:24 One month: 20 videos, #4 for Klaviyo on Upwork 9:45 Directing traffic, not doing the work 11:25 The 3-block day 12:13 DIY founders vs hiring an agency 13:39 Opportunity cost: the $25 email 14:46 The burden of proof is on the agency 16:55 Agree on a number before you hire 18:12 700+ YouTube videos as social proof 20:16 Where AI helps, and where it doesn't 21:46 "Open rates don't actually matter" 22:31 A Claude knowledge base built from every video 23:34 Clone your favourite YouTuber's playbook 25:00 Running account audits against your own SOPs Want this for your brand? https://pique.pro Gavin / In-Box: https://in-box.com/ Music: Chill Soul Rap Instrumental by Nkato   / nkato   Creative Commons — Attribution 3.0 Unported— CC BY 3.0 Free Download / Stream: https://bit.ly/chill-soul-rap-instrum...
