Outlook for Microsoft 365 · not mapped to an engine client yet Real screenshot
Outlook 2019 for Mac (legacy app) · not counted as Outlook for Mac Real screenshot
This is the legacy Outlook for Mac app. The new Outlook for Mac, which the table describes, drops gradients, grid sizing functions, var() and more.
Gmail (web) · not counted as Gmail Real screenshot
This Gmail install does not apply Gmail's sanitiser, so it shows more than real Gmail does.
Windows Mail · not mapped to an engine client yet Real screenshot

Caveats (2)

1. Gmail Android, Gmail iOS, Yahoo Mail, Yahoo Mail Android, Yahoo Mail iOS, AOL Mail: Partial. Logical property values inline-start and inline-end are not supported.
2. Outlook Classic: Not supported. table and img elements can use an align attribute to get a similar effect.
