HTML email

Design an HTML email as ONE self-contained .html file that survives real email clients. Email rendering is not browser rendering — Gmail, Outlook, and Apple Mail each strip or mangle different things, and the rules below are what reliably survives all three. When a rule here conflicts with normal web-design instincts, the rule wins.

Layout and styling:

  • Structure with nested <table role="presentation" cellpadding="0" cellspacing="0" border="0"> — no flexbox, no grid, no floats, no position. One centered wrapper table, max-width 600px, single-column flow (stacked rows beat side-by-side columns).
  • Inline EVERY style on the element it styles. A <style> block in <head> may additionally carry only what can't inline (media queries, dark-mode tweaks) — several clients drop it entirely, so the email must read correctly from inline styles alone.
  • No JavaScript anywhere (universally stripped). No external stylesheets. No web fonts — use email-safe stacks (Arial, Helvetica, Georgia, Verdana, Tahoma, 'Courier New') with generic fallbacks.
  • Build the visual design out of colored table cells, borders, spacer cells, and type — not images. There is nowhere to host project images from here: a referenced project file will not exist for recipients. If imagery is essential, leave a clearly-marked placeholder cell with alt text and tell the user to swap in a hosted https URL before sending.
  • Buttons are "bulletproof": a padded <td> with bgcolor and inline border-radius, the <a> filling it with display:block and inline color — never an image, never a styled <button>.

Client quirks that matter:

  • Outlook (Word engine): give every table/cell explicit widths; set line-height with mso-line-height-rule:exactly; wrap Outlook-only fixes in <!--[if mso]> … <![endif]--> conditionals.
  • Gmail clips messages beyond ~100KB of HTML — stay well under.
  • Add <meta name="color-scheme" content="light dark"> and pick colors that survive dark-mode inversion (avoid pure #000/#fff backgrounds; test text on mid-tone fills).

Deliverability and accessibility:

  • First element in <body>: a hidden preheader span (~85 chars) that previews next to the subject line.
  • alt text on any image, lang on <html>, real <a href> links (no dead # anchors), and a footer with a plausible unsubscribe line and postal address for anything marketing-shaped.

Show the design at 600px; mention in your reply that the file is send-ready HTML the user can drop into their email tool.
