What “tested” means here
Most free template galleries show you a screenshot. A screenshot is one client on one day. Every file on this page is run through the Emailens engine at build time, which resolves each CSS property and HTML element it uses against per-client support data and returns a score for all 21 clients separately. The number on each card is the worst of those 21, not an average, because the client that breaks your email is the one that matters.
The pattern that shows up across all 40 is worth knowing before you pick one: these are professionally built templates, and every single one of them still loses fifteen to thirty points in Outlook on Windows while scoring in the nineties everywhere else. That gap is the reason this gallery exists. Each template page shows you exactly where its own gap is.
