Case Study: THG achieves scalable global email and SMS marketing growth with SendGrid by Twilio

How THG delivers global email and SMS marketing campaigns for ecommerce growth

THG, a global ecommerce technology group and brand owner, needed a flexible email and SMS marketing platform to support rapid international expansion, brand acquisitions, and growing communication needs across multiple territories. The company was using Twilio SendGrid for email as part of its broader messaging stack, and needed a solution that could handle localization, database migrations, and scalable marketing across brands and regions.

SendGrid, alongside Twilio APIs and Professional Services, helped THG build a proprietary end-to-end ecommerce communications platform for email and SMS. The result was масштабable global messaging at high volume—about 1 billion emails and 3 million SMS per month, with email delivery rates of 98.6% over 12 months and 99.2% on Black Friday 2022—while also enabling better analytics, faster brand integration, and improved campaign optimization.
