Austin Tech Digest

It opens: "Austin, TX - Austin Convention Center 123 Main Street, 78701 Croft's in Austin is opening December 20th Hi Jane, Lorem ipsum, dolor sit amet consectetur adipisicing elit. Quia a assumenda nulla in quisquam optio quibusdam fugiat perspiciatis nobis, ad tempora...". Preheader: "Pre-header Text". Links: "sit amet consectetur", "RSVP Today", "Book an Appointment". 10 images, 50 Outlook-only blocks, no dark-mode query, system fonts.

The spread is what matters on this template: 100 in Superhuman against 55 in Outlook Classic, a 45-point gap across the same file. 3 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 227 warnings behind that score are concentrated there rather than spread evenly.

At 41.9KB compiled it has roughly 60KB 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: Imagery, colour and section order. This is the one category where restructuring is expected, and the per-client table on this page is how you check the restructure survived.

Leave alone: The image widths declared as HTML attributes as well as CSS. Outlook reads the attribute and ignores the stylesheet, so an image sized only in CSS renders at its natural pixel width and blows the layout out sideways.
