Email & SMS marketing
In-box
Gavin Hewitson is the founder of In-box, an email and SMS marketing agency for ecommerce brands. In-box is a Klaviyo Master Gold Partner and a certified Omnisend Partner. Over the past five years, Gavin and his team have built Klaviyo email flows, campaigns, sign-up forms and SMS programs for more than 500 Shopify and DTC brands. That work has helped them turn one-time buyers into repeat customers and grow revenue they own instead of renting it through paid ads.
He specialises in retention marketing: abandoned cart and browse abandonment flows, post-purchase automation, segmentation and email deliverability. For brands selling on Amazon and Shopify, he focuses on using email to move customers onto the brand's own store. Gavin also runs a YouTube channel with more than 700 email marketing tutorials. You can read his practical guides at in-box.com/insights and see client results in In-box's ecommerce email marketing case studies.
