Production guidance for display:grid

display:grid is a CSS property. Across the email client matrix, 17 of 21 tracked clients support it fully, 2 only partially, and 2 not at all. The clients most likely to require a workaround for this feature are Outlook (New), Outlook Classic, Gmail Android. Each of them needs a tailored fallback. See the per-client examples above for the specific code fix Emailens recommends.

When in doubt, ship a baseline that renders without display:grid and treat it as progressive enhancement on clients where support is verified. Emailens automatically detects cross-client divergence on this feature when you preview an email, so you can see exactly which template paths break before a campaign goes out.
