Feature Announcement · Barebone

It opens: "Barebones What's new from Barebones Release Notes Learn what's shipping this month, plus other Barebones updates below. Hello feature. Goodbye old feature. Ship updates in smaller, safer steps: clearer defaults, fewer clicks, and less context switching for your team. Try...". Preheader: "Release notes, Barebones". Links: "Read more". 11 images, 8 Outlook-only blocks, no dark-mode query, web font.

The spread is what matters on this template: 100 in HEY Mail against 64 in Outlook Classic, a 36-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 166 warnings behind that score are concentrated there rather than spread evenly.

At 23.7KB compiled it has roughly 78KB 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: The screenshots and the walkthrough copy. This is the longest thing most products send, which makes total size the constraint to watch rather than layout.

Leave alone: The heading hierarchy. It carries the outline screen readers announce, and flattening headings into styled text is the most common accessibility regression in announcement mail.
