The fix: file extensions
Webflow's AVIF conversion is triggered by the responsive-image pipeline. Reference the raw file with .png or .jpg in the URL and it serves the original format, which every email client renders.
Plan: self-host employer logos as named PNG/JPG files (/employer-logos/naturipe.png, etc.). Upload once per employer when they are onboarded. The template pulls logos by company slug, with no manual swapping per send.
This logo pipeline can live alongside our existing Webflow asset setup. It is a parallel pipeline, not a replacement.
