Notes on this template
It opens: "New dreams, new hopes, new experiences and new joys, we wish you all the best for this New Year to come in 2018! Simply created on Mailjet Passport [[DELIVERY_INFO]]...". 4 images, 19 Outlook-only blocks, no dark-mode query, system fonts.
The spread is what matters on this template: 100 in Superhuman against 73 in Outlook Classic, a 27-point gap across the same file. 4 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 135 warnings behind that score are concentrated there rather than spread evenly.
At 13.8KB compiled it has roughly 88KB 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.
