About this Outlook Templates email template

The Invoice Outlook email template is built specifically for Microsoft Outlook compatibility — Outlook 2016, 2019, 365 desktop, and Outlook on the Web. Outlook is the trickiest email client to design for: the desktop versions render HTML using Microsoft Word, which doesn't support modern CSS like flexbox, grid, or background images. SmartMailing's AI-generated Outlook email templates are hand-coded with table-based foundations, mso-conditional comments where needed, and tested specifically in the Word-based renderer that breaks 80% of "modern" templates.

When to use this Outlook template

Best practices for Outlook email templates

• Use table-based layouts. Outlook desktop uses Microsoft Word as its rendering engine; flexbox and grid don't work.
• Inline all critical CSS. `<style>` blocks are partially supported; inline styles are the only safe path for layout.
• Avoid background images on buttons — Outlook strips them. Use solid-color table cells with VML fallback if you need a colored button.
• Stick to web-safe fonts (Arial, Helvetica, Verdana, Georgia). Custom fonts fall back to Times New Roman, which often breaks the design.
• Use mso-conditional comments for Outlook-only fixes. They let you target Outlook with code that other clients ignore.
• Test specifically in Outlook 2016 — it's the version with the most rendering quirks and accounts for ~5% of the global Outlook install base.
