I've designed and/or developed a wide variety of emails during my time at Vrbo/Expedia. While Vrbo already had an existing design system in place, it's been fun and challenging to create visually beautiful, engaging email templates that still followed html email best practices.
I also helped create and maintain Vrbo's email style guide and design system, including a Figma library of components and templates - so other designers can build email mocks like lego blocks!
