It opens: "the only way to travel Hey {{FirstName}} It's been a long time since you last traveled with us. Have a look at some of the top destinations people are booking right now! New York $399 London $399 Berlin $399 Best,...". 5 images, 20 Outlook-only blocks, no dark-mode query, web font.

The spread is what matters on this template: 100 in Apple Mail iOS against 73 in Outlook Classic, a 27-point gap across the same file. 2 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 157 warnings behind that score are concentrated there rather than spread evenly.

At 17.7KB compiled it has roughly 84KB 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.

Safe to customise: Copy, colour and imagery.

Leave alone: The table structure. It is what holds the layout together in Outlook, which resolves widths from cells rather than from CSS.
