The spread is what matters on this template: 100 in Superhuman against 88 in Outlook Classic, a 12-point gap across the same file. 15 of the 21 clients render it without a single flagged property. Outlook Classic is the one to preview against after any edit, because it is where this template has the least margin, and the 83 warnings behind that score are concentrated there rather than spread evenly.

At 6.1KB compiled it has roughly 96KB of headroom before Gmail clips the message at 102KB and hides the rest behind a "View entire message" link. Inlined CSS and base64 images both count toward that, so watch it as you add sections.
