HTML Newsletter for Seasonal Promotions

I need a single-page HTML newsletter that spotlights our upcoming seasonal campaigns. The goal is purely promotional, so every section—from hero banner to closing call-to-action—must inspire readers to explore the new season’s range and click through to our site. Technical notes • Code must be responsive and render flawlessly in the latest versions of Outlook, Gmail, Apple Mail, and major mobile clients. • Keep CSS inline and minimise external assets to ensure deliverability. • Optimise images for fast load times; supply fall-back colours for background images. • All links, alt text, and tracking placeholders should be clearly marked so my marketing team can swap in final URLs and UTM parameters. Content structure Hero banner → brief intro copy → featured products (three slots) → limited-time seasonal offer section → footer with social icons and unsubscribe link. Deliverables 1. Commented HTML file ready to import 2. A zipped folder containing all referenced images (or placeholders). 3. A quick preview screenshot showing desktop and mobile breakpoints. Acceptance criteria • Passes Litmus or Email on Acid tests with no critical issues. • Mobile viewport scales without horizontal scrolling. • All text remains selectable; no text locked inside images. If any clarifications are needed, let me know so we can hit the ground running.
