AT&T iPhone Upsell

This project was a personalized AT&T upsell email focused on driving device upgrades through dynamic, data driven content. I built the template to swap in customer specific details like first name and offer messaging, with guardrails and fallbacks to keep the experience polished even when data was incomplete. The layout was designed to keep the offer front and center on both desktop and mobile, while meeting accessibility standards with clear structure and meaningful alt text.

Under the hood, the build prioritized scale and inbox safety. Image assets were tuned for fast loads, the image to text balance was kept in check for deliverability, and mobile image swaps were used where it improved clarity. The template was tested across major clients and devices, resulting in a flexible, performance minded campaign that paired personalization with reliable rendering.
